We present the articles of the third issue of scientific journal "Mining Science and Technology” (Russia) for 2024:

A systematic approach to evaluating environmental safety in metro operations, based on modelling the development of defects in tunnel structures under the influence of hydrogeological factors, will help organize existing information on potential accidents and develop monitoring methods and measures to minimize risks that compromise the environmental sustainability of underground transport infrastructure.

🔥 Ash and slag dumps – worthless waste or hidden treasure?

Did you know that ash and slag dumps may contain hundreds of tons of valuable metals? Researchers have proven: ash processing is not just about ecology—it’s a profitable business!

What was found in the dump?
✔️ Titanium (785 t) – for aerospace industry
✔️ Strontium (183 t) – for electronics and medicine
✔️ Iron (4,867 t) – for metallurgy

Why does it matter?
🌱 Ecology: Processing just 10% of the dumps reduces environmental harm by 20%.
💰 Economics: The project pays for itself in 4 years.

How does it work?
• Gravity separation – sorting ash into fractions
• Magnetic separation – extracting metals
• Concentrate sales – ready-to-use industrial product

What’s next?
The technology is set to be implemented soon. Perhaps soon, power plant ash will be valued as highly as ore deposits!

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.

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.
