FIELD: hydroelectrometallurgy. SUBSTANCE: invention relates to hydrometallurgic processing of solid metal-containing mineral raw material - ores, concentrates, wastes from ore enrichment and other metal-containing wastes (coal production, ashes, drosses from heat power stations, etc.). Method includes stripping of mineral raw material, extraction of metal ions, separation of extract from stripping agent, and electrolytic isolation of metals from extract. Metals are possibly isolated directly from extract. When separated, stripping agent is returned into stripping stage. It is also possible that worked out extractant is returned into extraction stage. EFFECT: enhanced efficiency of process. |
