We present the articles of the first issue of scientific journal "Mining Science and Technology” (Russia) for 2025:
Scientists have developed a new method for producing adsorbents to extract heavy metals from mining wastewater. Mining and metallurgical operations generate large volumes of liquid waste containing valuable components. Processing copper-zinc ores produces metal-laden effluents with a wide range of accompanying elements, complicating treatment due to low concentrations of individual components and pH fluctuations. Heavy metals such as Cu²⁺, Zn²⁺, and Fe²⁺ are highly toxic, non-biodegradable, and can accumulate in living organisms, posing risks to ecosystems and human health. Researchers proposed using zeolites based on kaolin and bentonite as an efficient alternative to chemical precipitation. These adsorbents exhibit high ion-exchange capacity, are easily regenerated, and release non-toxic Na⁺ cations into the environment. The novelty of the method lies in using waste Al₂O₃–NaAlO₂ suspension to adjust the composition of the alkaline alloy during zeolite synthesis, ensuring a specific crystalline structure. The technology involves alkaline fusion of bentonite or kaolin with sodium hydroxide, followed by dissolving the alloy in water, filtration, and hydrothermal crystallization. Optimized synthesis conditions achieved a metal recovery rate of 95% from model solutions with initial concentrations of 150 mg/L Cu²⁺, 180 mg/L Zn²⁺, and 125 mg/L Fe²⁺. The resulting zeolite adsorbents can be used to treat metal-contaminated water in closed-loop water systems, reducing environmental impact and conserving resources.

How to Improve Block Stone Quality with Blasting Technology?
The extraction of block stone is a critical process in the construction materials industry, where maintaining the integrity of the material for further use is paramount. The key challenge lies in minimizing induced fracturing and surface roughness of the blocks.
🔹 Key Aspects of the Technology:
✔️ Stress wave interaction – plays a decisive role in forming the main rupture between blastholes.
✔️ Optimal charge parameters – blasthole spacing, blast product pressure, and linear charge density influence the zone of induced fracturing.
✔️ Orientation of the rupture plane – aligning it with natural fractures in the rock mass increases the yield of high-quality blocks.
🔹 Research Findings:
✔️Numerical modeling confirmed that adjusting charge parameters localizes the fracture zone.
✔️Reducing blasthole spacing while increasing charge size within limits ensures directional splitting.
For more information, see the article:

🚫 Shotgun Submissions to Academic Journals: The Hidden Victims of Your 'Clever' Tactic
It might seem logical – submit your paper to ten journals, and your chances of publication increase. But behind each such action stand real people forced to work in vain.
Why this is more than just "bad manners"?
1️⃣ Editors waste their time:
✔️ checking compliance (dozens of formatting requirements);
✔️ manually searching for reviewers (sometimes for weeks!);
✔️ coordinating correspondence between authors and experts.
2️⃣ Reviewers work for free:
✔️ spending 5-10 hours analyzing your paper;
✔️ formulating detailed comments;
✔️ do you really think their time is worthless?
3️⃣ Technical staff do double work:
✔️ Preparing materials for publication;
✔️ Verifying metadata and references;
✔️ Formatting text to editorial standards.
...And all this – for NOTHING, if the paper is already accepted elsewhere.
💰 The financial impact:
✔️ journals pay staff for this work;
✔️ some order translations of abstracts/papers, even reviews;
✔️ plagiarism check systems require license fees.
Your "time-saving" tactic causes real financial losses for publishers.
⁉️ What about your colleagues?
The ugliest consequence – innocent co-authors get caught in the crossfire. Upon encountering dishonest authors, journals may:
✔️ reject all listed authors – even those unaware of multiple submissions;
✔️ blacklist the entire research group/institution;
✔️ scrutinize future submissions from the same university/lab.
You're risking not just your reputation, but the careers of those who trusted you as co-authors.
⁉️ Will your employer find out?
❗️YES! Many journals upon detecting shotgun submissions:
✔️ officially notify the author's institution;
✔️ include violation details in rejection letters;
✔️ publish retraction notices specifying the reason.
Consequences for the author:
⚠️ reputational damage among peers;
⚠️ PhD defense issues;
⚠️ grant application problems (funds check publication history);
⚠️ workplace disciplinary actions.
How to proceed ethically?
✅ One journal, one submission!
✅ If urgent – email the editor BEFORE submitting:
"Are you willing to consider this paper under accelerated review?"
✅ After rejection – revise and submit anew.
P.S. Some publishers now impose penalties for shotgun submissions – up to complete publication bans in the journal or entire publisher portfolio.
🔗 Helpful links:
COPE on multiple submissions
Did you know...
Some editorial boards now share information about such cases? Gambling with your reputation is a bad idea!

We present the articles of the first issue of scientific journal "Mining Science and Technology” (Russia) for 2025:
Scientists studied finely ground tailings from the flotation processing of slags at the Sredneuralsky Copper Smelter ("SUMZ technical sands"), which contain zinc (3.3–3.9%) and copper (0.4–0.5%). These wastes can serve both as a source of valuable metals and as a potential environmental hazard. The study examined the material composition of the magnetic fractions of the "technical sands" and evaluated the efficiency of wet magnetic separation for extracting valuable components. Chemical and phase analyses revealed that zinc and copper were distributed relatively evenly across the fractions, with a slight increase in copper in the non-magnetic fraction and zinc in the weakly magnetic fraction. The application of wet magnetic separation under standard conditions proved insufficiently effective, indicating the need for further research to optimize the technology. The results are important for developing new methods of processing copper smelting waste and reducing its environmental impact.

🔍 Why are waters in granite quarries more dangerous than others?
A new study of the granitoids in the Ob-Zaisan fold zone (Novosibirsk Oblast) has revealed alarming findings:
💧 The radioactivity of water in granite quarries is 100–1000 times higher than in other rock types!
📊 Record-breaking concentrations:
❗️Uranium (²³⁸U) – up to 1.4 mg/dm³
❗️Thorium (²³²Th) – up to 2.16·10⁻³ mg/dm³
❗️Radon (²²²Rn) – up to 5000 Bq/dm³ (in areas with granitoid development)
❓What’s the Reason?
The high radioactivity is linked to mineral accumulators (monazite, xenotime, fluorite), which are particularly abundant in the Barlak granitoid complex.
🔬 Key Conclusion:
Granite massifs are natural sources of radiation, requiring:
✅ Regular water monitoring.
✅ Radiation risk assessments.
✅ Special protective measures for quarry workers.

We present the articles of the first issue of scientific journal "Mining Science and Technology” (Russia) for 2025:
Scientists studied the effect of hydraulic excavator pump wear on fuel overconsumption. During operation, increased clearances, reduced volumetric efficiency, and higher energy losses lead to excessive fuel consumption. The research aimed to determine the optimal pump service life considering growing fuel costs. The team developed a mathematical model of pump ownership costs, created simulation algorithms in Simulink-Matlab, and evaluated fuel consumption increases. Using the Komatsu PC2000-8 excavator as an example, the study demonstrated how main hydraulic pumps' technical condition affects fuel overconsumption. The results established correlations between fuel overconsumption and pump wear, plus derived an equation for optimal replacement timing to minimize total costs. The proposed fuel overconsumption indicator (calculated as the ratio between actual and nominal fuel consumption per 1 m³ of excavated material) enables data-driven determination of pumps' critical wear threshold. Implementation of this model can reduce combined pump ownership and fuel costs by up to 17%, accounting for pump condition deterioration rate, fuel prices, replacement costs, and mining-engineering conditions. All simulations were performed using Simulink-Matlab and Excel with specially developed calculation methodologies.

How to determine the deformation modulus and anisotropy in blocky rock masses?
🔹 In a study published in Mining Science and Technology (Russia), the authors investigated the anisotropic behavior of blocky rock masses. They employed the discrete element method to model and analyze the deformation modulus as a function of loading direction, joint properties, and intact rock characteristics.
🔹 Key Findings:
✔️ The deformation modulus depends on the Joint Roughness Coefficient (JRC) and the Uniaxial Compressive Strength (UCS) of the intact rock.
✔️ The influence of joint roughness on the deformation modulus is three times greater than that of intact rock strength.
✔️ The degree of anisotropy in the deformation modulus ranged from 1.6 ≤ Rₑ ≤ 2.5, with an average value of 1.88.
✔️ During joint sliding failure, the yield strain (0.2–0.4) is independent of the loading angle (θ) and the orientation of the third joint set (α).
🔹 Practical Applications:
The results enable the prediction of rock mass behavior without costly field tests, which is crucial for designing tunnels, boreholes, and other geotechnical structures.

We present the articles of the first issue of scientific journal "Mining Science and Technology" (Russia) for 2025:
Scientists have developed a mechatronic system for testing gearboxes in mining shovels. The mechanical transmissions of hoist and drag winches, as well as crowd mechanisms, operate under extreme variable and shock cyclic loads, requiring strict quality control. The new test bench performs running-in and acceptance testing of gearboxes under conditions closely simulating actual operation. It supports testing for various shovel models including EKG-8US, EKG-10, EKG-12K, and others. The system uses DC motors (350 kW and 560 kW) and standard transistor converters with PWM control. The software, based on the "Pulsar-7" diagnostic system, provides manual and automatic control, multiple loading modes (constant, variable, cyclic), automated test reporting, and excavation cycle simulation.

Scientists have developed a mechatronic system for testing gearboxes in mining shovels. The mechanical transmissions of hoist and drag winches, as well as crowd mechanisms, operate under extreme variable and shock cyclic loads, requiring strict quality control. The new test bench performs running-in and acceptance testing of gearboxes under conditions closely simulating actual operation. It supports testing for various shovel models including EKG-8US, EKG-10, EKG-12K, and others. The system uses DC motors (350 kW and 560 kW) and standard transistor converters with PWM control. The software, based on the "Pulsar-7" diagnostic system, provides manual and automatic control, multiple loading modes (constant, variable, cyclic), automated test reporting, and excavation cycle simulation. A mathematical model was developed in Simulink to simulate the running-in process. The test bench has been successfully implemented in industrial applications.

How to increase diamond recovery using froth separation?
A new study reveals innovative methods to improve the efficiency of froth separation for diamond-bearing kimberlites. Researchers have proposed solutions that could reduce diamond losses by up to 20%!
🔹 Key Findings:
1. Restoring diamond hydrophobicity by removing mineral coatings through combined treatment: thermal, ultrasonic, electrochemical, and reagent conditioning.
2. Optimal temperature regime:
- heating the feed to 85–90°C for preparation;
- conditioning at 30–40°C;
- separation at 20–24°C.
3. Collector optimization:
- adding low- and medium-molecular fractions increases collector efficiency by 16%;
- ketone additives enhance adhesion activity up to 87%.
4. Closed-loop water recycling with clarification reduces reagent consumption by 8% without compromising concentrate quality.

We present the articles of the first issue of scientific journal "Mining Science and Technology" (Russia) for 2025:
Scientists have analyzed energy efficiency of mining operations, focusing on ventilation fans and hoisting machines as the most energy-intensive equipment. The study examines main ventilation fans and hoisting systems at Molibden mine, proposing optimization measures to improve efficiency and reduce costs. Research methods included analytical approaches for ventilation system evaluation. Findings show inefficient fan operation with excessive energy use, suggesting motor replacement could save 4.9 million rubles annually. Analysis of hoisting equipment recommends modern multi-rope systems for better performance. Data reveals inverse correlation between productivity and energy use - 10–15% output increase reduces energy consumption by 2–5%. Implementing automated controls and optimizing equipment utilization can significantly enhance efficiency. These results are applicable to other deep mining operations.

How to enhance flotation efficiency of complex ores using electrochemistry?
A new study proposes an innovative approach to flotation beneficiation based on direct potentiometry methods. Researchers have demonstrated that monitoring the electrochemical parameters of pulp can increase process efficiency by 7.8% while reducing reagent consumption!
🔹 Key Findings:
1. Electrochemical monitoring using ion-selective sensors (pH, Ag₂S, Pt) enables real-time determination of optimal reagent dosages.
2. Maintaining the Ag₂S electrode potential at -450 mV increased copper recovery in the concentrate to 83.1% (compared to 75.8% with conventional methods).
3. Reduced research time through automated pulp analysis and elimination of labor-intensive experiments.
4. Potential for AI integration to develop a "digital assistant" for flotation operators, capable of adapting to changes in ore composition.

We present the articles of the second issue of scientific journal "Mining Science and Technology" (Russia) for 2025:
Scientists have proposed a new approach to calculating the optimal width of a dredge front bank, which reduces the cost of placer deposit mining. The study demonstrates that existing methods, focused solely on maximizing dredge productivity, fail to minimize costs when the depth of the placer and overburden thickness increase. The authors developed a methodology for determining the front bank width that accounts not only for dredge performance but also for stripping costs and the extraction of valuable components. The research analyzed the influence of placer parameters (peat thickness, productive layer thickness, front bank width) on economic efficiency, evaluated over 100 process flow sheets for equipment operation, and provided their economic assessment. The results include recommended correction factors for calculating the optimal front bank width, serving as a methodological foundation for designing dredge mining systems.

🔍 Hidden Layers in Permafrost: New Study Decodes GPR Interpretation Challenges
Ground-penetrating radar (GPR) is indispensable for subsurface exploration, but interpreting data in complex multilayered permafrost remains problematic. A new study offers a solution to accurately determine rock properties in permafrost environments.
🔥 Key Findings:
1. Layered Media Model
A mathematical model describes EM wave behavior through alternating frozen/thawed layers, focusing on hyperbolic signatures in radargrams — critical for data interpretation.
Important limitation:
❗️ The model excludes EM wave dispersion/absorption effects.
2. Measurement "Deception"
A mere 0.5 m thawed layer (within a 4.5 m rock mass) can reduce apparent wave velocity by ~10%, while remaining undetected in standard analysis.
3. Digital Validation:
Simulations in gprMax and GeoScan32 confirmed model accuracy with <0.5% error.
🛠 Applications:
✔️ improved ground stability assessment for construction;
✔️ detection of hazardous thawed layers;
✔️ enhanced automated GPR data processing.
⚙️ Technical Specs:
✔️ Ricker pulses at 400 MHz;
✔️ Up to 9 layers analyzed;
✔️ Dielectric permittivity: ε'=4–20.

We present the articles of the second issue of scientific journal "Mining Science and Technology" (Russia) for 2025:
Scientists have studied the geological structure of the West Siberian Oil-and-Gas Province (OGP) to establish relationships between local strike-slip dislocations of the Russko-Chaselsky Ridge and the regional Pai-Khoi–Altai shear zone. The research aimed to identify patterns of hydrocarbon accumulation associated with fault systems in this zone. Using 2D/3D seismic surveys and digital models of gravity/magnetic fields, the team analyzed crustal deformation features within the shear zone, mapping sedimentary cover and basement structures. Results show that Pai-Khoi–Altai shear zone dislocations exhibit right-lateral strike-slip morphology, forming a hierarchical system with en echelon faults and Riedel shears. In the Russko-Chaselsky Ridge, these structures interact with graben-rift systems, creating submeridional deformation zones in the platform cover and upper basement. Seismic interpretation revealed "flower structures" extending from Lower Cretaceous to Paleozoic strata, which may serve as hydrocarbon migration pathways in the West Siberian OGP. These findings improve predictions of oil/gas accumulation in fault-controlled traps.

Scientists have studied the geological structure of the West Siberian Oil-and-Gas Province (OGP) to establish relationships between local strike-slip dislocations of the Russko-Chaselsky Ridge and the regional Pai-Khoi–Altai shear zone. The research aimed to identify patterns of hydrocarbon accumulation associated with fault systems in this zone. Using 2D/3D seismic surveys and digital models of gravity/magnetic fields, the team analyzed crustal deformation features within the shear zone, mapping sedimentary cover and basement structures. Results show that Pai-Khoi–Altai shear zone dislocations exhibit right-lateral strike-slip morphology, forming a hierarchical system with en echelon faults and Riedel shears. In the Russko-Chaselsky Ridge, these structures interact with graben-rift systems, creating submeridional deformation zones in the platform cover and upper basement. Seismic interpretation revealed "flower structures" extending from Lower Cretaceous to Paleozoic strata, which may serve as hydrocarbon migration pathways in the West Siberian OGP. These findings improve predictions of oil/gas accumulation in fault-controlled traps.

How to Assess Rock Mass Stability at Deep Mine Levels?
Geomechanical rating classifications are key tools for designing underground mining operations. A new study presents a detailed assessment of rock mass conditions at deep levels of the Udachny mine using RMR and Q systems.
🔹 Key Findings from the Study:
• RMR: Range of 32–62 at Q = 1, median values:
o kimberlites of the Zapadny Ore Body (ZOB) — Class III stability;
o kimberlites of the Vostochny Ore Body (VOB) — Class IV;
o host rocks — Class II (average RMR = 54).
• Q-Index: Logarithmic range of 0.18–105.6, median values:
o VOB — Class D (poor condition);
o ZOB — Class C (fair condition);
o Host rocks — Class B (Q ~ 4–10).
• Rock Strength (UCS):
o kimberlites: 2.15–119.48 MPa (variability due to heterogeneous composition)
o host sediments: 28.14–71.73 MPa (average: 41.05 MPa)
• Jointing:
o host rocks — Class I (monolithic, >2 m spacing);
o ZOB — Class III (0.5–1 m spacing);
o VOB — Class IV (0.1–0.5 m spacing).
🔹 Practical Recommendations:
• for permanent workings: rockbolting (2 m length, 1–4 m spacing) with 5–6 cm shotcrete;
• for excavation junctions: reinforced support (2.5 m rockbolts, 9–12 cm shotcrete);
• moderate correlation between RMR and Q due to differing parameter sensitivities (e.g., RMR ignores rockbursts, Q omits strength).
The study highlights the need for integrated approaches: ratings require continuous updates as mining progresses.

We present the articles of the second issue of scientific journal "Mining Science and Technology" (Russia) for 2025:
Scientists have conducted an in-depth study of Russia's cobalt resource base, providing new insights into the distribution of 1,562.3 thousand tons of cobalt reserves across 25 ore provinces and 150 major deposits. The research reveals that 62.5% of reserves are associated with copper-nickel deposits in the Norilsk region, while silicate-cobalt-nickel formations account for 19.9% of resources. A special focus was given to emerging sources of cobalt, including deep-sea ferromanganese crusts in the Magellan Mountains (110 thousand tons Co) and Clarion-Clipperton nodules (985 thousand tons Co). The study offers comprehensive recommendations for improving resource estimation methods and implementing innovative mining technologies like in-situ and heap leaching to develop hard-to-process ores more efficiently.
