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.

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

The problem of biological reclamation was studied in the Kizel Coal Basin area. The effectiveness of reclamation was evaluated on several sulfide coal waste dumps. The reclamation methods, as well as the period of soil-vegetation cover formation, varied. Agrochemical properties of the dump soils were studied using unified methods. The NDVI (Normalized Difference Vegetation Index) was calculated based on Sentinel-2 and Landsat 7,8 images. To assess biological activity, phytotesting was used. The lithostrats ranged from slightly acidic to neutral (рН–Н2О = 6.1–6.8); the embryonic soil showed a slightly alkaline reaction (7.9). The embryonic soil, due to the presence of coal particles, had the highest organic matter content (12–7.7%). Depending on the "age" of the soil, the amount of organic matter in the lithostrats varied: for the 7-year-old lithostrat, it ranged from 2.4 to 8.9%, while for the 4-year-old lithostrat, it was less than 1%. The absorption capacity of the lithostrats was similar to that of the background soil. The dump soils were characterized by low levels of nutrients (NPK), with the 4-year-old lithostrat having the lowest N content. The dump soils demonstrated favorable conditions for plant growth, as evidenced by the height and biomass of cress and oats. The calculated NDVI for all dumps ranged from 0.4 to 0.6, indicating the presence of a stable vegetation cover. The implemented reclamation measures proved to be effective.

🔥 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!

For more information, see the article:

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.
