Electrochemical action on the flotation beneficiation of ordinary iron ore concentrate

The main challenge in processing fresh ferruginous quartzites is to obtain high-quality iron ore concentrates containing more than 70% total iron and less than 1.8% silica to produce DR pellets and hot Briquetted Iron (HBI). The journal "Mining Science and Technology" (Russia) presents research results aimed at improving the quality of the oversize of the fine screening of ordinary magnetite concentrate from Mikhailovsky GOK, named after A. V. Varichev, through the use of electrochemically treated solutions of cationic amine class collectors in the process of reverse cationic flotation. The research findings confirmed the feasibility of using preliminary diaphragmless electrochemical treatment of reagents Tomamine RA-14 and Lilaflot 811M (esters of monoamine of different composition) for the targeted modification of their properties and for increasing the efficiency of reverse flotation. Consequently, the silica content in the flotation cell product decreased from 1.66–1.7% to 1.51–1.56, with the grade of total iron exceeding 70%.

How to increase KCl recovery during beneficiation of natural potash ores?

The main source of potassium fertilizers is sylvinite ores consisting primarily of halite (NaCl), silicate and clay-carbonate slurries (clay-salt slurries). Processing of natural potash ores is mainly carried out by the flotation method, which separates KCl, NaCl, and clay-salt slurry. The research is aimed at revealing the effect of sonochemical pretreatment of the depressor reagents, CMC and starch, on dynamic viscosity, aggregate size, electrokinetic potential of these reagent solutions and sylvin flotation performance. Sonochemical pretreatment of sylvin flotation depressors contributes to an increase in KCl recovery and a decrease in the slurry content in the flotation concentrate.

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

“Invisible” gold is referred to submicroscopic gold particles that are 1–100 nm in size and are not detected using optical or electron microscopy. The presence of “invisible” gold and silver in ores complicates the selection of flow charts for their processing and owes the necessity for the development of new process solutions and improvement of existing ones. Experiments have shown the necessity of using magnetite to achieve coarsening fine silver particles. The optimal magnetite content is 10%, which leads to the formation of spherical aggregates of silver with a size of 20-40 microns. As a result of processing, it was possible to increase the particle size of precious metals up to 20-50 microns, which can then be extracted using traditional enrichment methods.

The next issue of the journal "Mining Science and Technology" (Russia)!

We present one of the problematic aspects of the articles in the new issue.

⁉️ How can the technological processes of drilling in hydrocarbon fields be improved?
New solutions to improve the quality of drilling in the Mesopotamian region of Iraq. Wells drilling and completion account for over 40% of all investments in the hydrocarbon energy industry. Reducing failures during the drilling process is one of the key prospects for increasing effective drilling time and addressing challenges faced during drilling and their consequences. The main types of complications in the wells drilling process include sticking of the drill string due to deviation, collapsing of unstable rocks, narrowing of the wellbore from crumbling rocks, absorption of drilling mud, gas-oil-water showings, and brine showings. Research conducted in the Mesopotamian basin of Iraq has revealed that there are technological solutions to improve the efficiency of drilling operations.

You can learn more from the review article, which will be published in the next issue before the end of this year.

This and much more is on the pages of our new issue!

How can the efficiency of flotation processing of complex ores be improved?

Flotation beneficiation plays a leading role in the processing most ores. The efficiency of this process is ensured by the correct selection of operating modes, which involves choosing the most selective reagents and determining their optimal consumption. The conducted research, presented in the journal Mining Science and Technology, allowed to find a new methodological approach to the study of ore flotation beneficiation using ionometry methods. The data obtained from ion-selective sensors significantly deepen our insight into the transformations occurring during the flotation process and allow for consideration of possible adverse factors that hinder effective process progression. A universal flowchart for flotation studies with ion-selective sensors has been developed, facilitating the application of this approach to various ores. The implementation of the results from this comparative analysis has led to a 7.8% increase in beneficiation efficiency while reducing reagent consumption. Additionally, the insights gained into the electrochemical processes occurring allowed for assumptions about the adverse factors affecting flotation outcomes. In conclusion, a model for the potential application of this approach at existing enterprises was proposed, including the implementation of an “intelligent assistant” for flotation operators based on the developed electrochemical models.

Dry technologies for processing and enrichment of mineral raw materials - pros and cons!

The use of dry methods of processing and beneficiation of mineral raw materials is one of the promising areas, as this approach to concentrate production is less energy-consuming, less labor-intensive, and economically beneficial. However, this method of enrichment is not always technologically effective. Experimental studies on the experimental studies on preliminary dry separation of Arkachan deposit ores to determine the quality of beneficiation of the separation products are presented in an article in the journal Mining Science and Technology. The results of the study showed, dry beneficiation as applied to the ores of Arkachan deposit is technologically inefficient. Additional laboratory studies of pneumatic separation processes at high degree of ore materials grinding are required. The authors of the study are confident that their methodological approach will be useful for colleagues in substantiating technologies for processing and beneficiation of mineral raw materials.

🔥 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!

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.

✔️ 27.35% in -0.2+0.1 mm class;
✔️ 11.75% in -0.1+0.071 mm class;
✔️ 23.46% in -0.071 mm class;
→ Total 62.56% in particles <0.2 mm

Method Efficiency:
✔️ pneumatic Separation: 35.25% recovery at 1.8 t/h;
✔️ GRG Test: 73.91% recovery with grinding to 80% passing 0.071 mm.

GRG Test Results by Stage:
✔️ Stage 1 (-1 mm): 40.20% recovery;
✔️ Stage 2 (-0.315 mm): +14.46%;
✔️ Stage 3 (-0.071 mm): +20.88%.

Conclusions:
1. Dry methods are ineffective for fine-grained gold (<100 µm).
2. Gravity separation requires fine grinding but achieves high recovery.
