🔥 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 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.
For details, see the article in Mining Science and Technology:
