How to enhance the efficiency of reverse flotation of iron ore concentrates through electrochemical treatment of reagents?
The most effective methods to achieve high-quality iron ore concentrates is through reverse flotation using cationic amine collectors in an alkaline medium. However, due to the very fine impregnation of magnetite in quartz, the insufficiently complete release of magnetite even with fine grinding, and the proximity of the flotation (surface) behavior of the separated minerals, high-quality concentrates are not always achievable in the flotation process. 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%.

🔥 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:
