Within the last century in ore mining industry regions technogenic formations deposits were formed, to which we can refer mining enterprises dumps, dumps of concentrating plants, ash dumps of fuel and energy complexes, slags and slimes of metallurgical productions, slime and slag dumps of a chemical branch. By present time nearly 10 bln. tons of technogenic wastes is accumulated in Russia, inflicting colossal damage to environment.
«Uralmekhanobr» Institute traditionally pays special attention to the problem of technogenic wastes disposal. Lately, we developed concentration technologies for slags of copper smelting production, SDPP ashes, clinkers of zinc production, red muds of aluminum production, greasy scales, out of balance ores, wastes of nonferrous metals ores mining, pyrite cinders.
We perform:
- Development of flowsheets for copper flowing and aged convertor slags with a maximum copper recovery when using ultra-fine grinding;
- Development of schemes for getting reusable raw materials from clinkers of zinc production plants;
- Development of magnetic-gravity flowsheets of red muds – refinery complex wastes from aluminum smelters to get iron concentrate;
- Development of processing schemes for greasy scales;
- Development of magnetic-gravity processing schemes for iron bearing slimes- concentrating plants wastes;
- Development of hydrometallurgical and combined processing schemes of concentrating plants wastes in the field of non-ferrous metallurgy.
