Development of Technology for Processing Pyrite Cinder to Produce Non-Ferrous Metal Concentrate
نویسندگان
چکیده
The existing technologies for processing of pyrite cinder require improvement complex extraction non-ferrous, precious metals and iron. novelty the technology used in work cinders is preliminary chemical activation a solution sodium bicarbonate. optimal modes were determined according to temperature, duration, L:S ratio NaHCO3 concentration. It has been established that results changes phase composition reduction content impurity components P2O5, SO3 As2O3. leaching after pre-activation 15 % H2SO4 resulted an into solution, wt. %: CuO 76, 8; ZnO 75, 9 Fe2O3 26, 0. degree non-ferrous sulphuric acid without lower by - 20 %.
