Annotatsiya

The results of the extraction of iron, copper, and precious metals from solid waste (cakes) of soda leaching of calcined molybdenum intermediate product are presented. According to IR spectroscopy and RFA data, the cake contains Mo, Re, Cu, Fe, etc.; Fe(OH)3·nH2O, MoO2/MoO3, MoS2 phases, as well as molybdate compounds (CuMoO4, ZnMoO4, CaMoO4, PbMoO4, Fe2(MoO4)3) were identified. The cake is finely dispersed (up to 95% <0.074 mm), has a specific gravity of ~1.33 t/m3, and weak magnetic properties due to hydrated iron oxides. A scheme of wet magnetic separation with a gradual increase in magnetic induction with the addition of 0.5-0.8% of magnetite particles (for magnetization of weakly magnetized particles) and ~1 g/t of polyacrylamide was developed and tested. A magnetic concentrate with a Fe content of 26-27% was obtained, in which Cu was reduced to ~0.05% and Mo to ~0.2%; the non-magnetic fraction was enriched with Mo (~5.2%) and Cu (~2.4%) and sent for further hydrometallurgical processing (extraction of copper and rare metals). Material balance and tests have shown the technological feasibility and selectivity of the proposed approach to the integrated disposal of leaching cakes.
