PURIFICATION OF SULPHATE CONTAINED TECHNOLOGICAL SOLUTIONS FROM ARSENIC BY HYDROLYTIC PRECIPITATION AND RECEIVING OF SELECTIVE Cu, Zn, Co, Mn CONCENTRATES

In the article information is given about tailings which were received from enriching of iron ore irrigated by heap leaching method purification of As by hydrolytic precipitation and receiving selective Cu, Zn, Co, Mn concentrates. As a research materials were used tailings from Dashkesan Ore Purification factory and solutions which were received after irrigation of processing of North Dashkesan Co deposit. In percolation columns content of solutions received after irrigation are as follows (I sample at pH=2): Al – 3.23, Fe –13.63, Mn – 1.89, Cu – 0.64, Co – 5.8, Zn – 89.16; (II sample, pH=4.8); Ca – 223, Mn – 13.83, Co – 478, Cu – 10.2, Zn – 4.34. Precipitation of valuable components by hydrolytic method from received solutions by increasing pH from 1 to 11 provided stage by stage and as a result were received 3 type concentrates
