Abstract

Procedeul de prelucrare a minereurilor complexe polimetalice, conform inventiei, prevede flotarea colectiva a minereurilor sulfuroase si a celor oxidate dupa o prealabila sulfurare, dupa care concentratele complexe rezultate sunt tratate, în prima faza, cu solutii de CaCl<sub>2</sub> a caror concentratie initiala este în jur de 200 g/l CaCl<sub>2</sub> si 10 ... 50 g/l HCl, temperatura de 85 ... 100 degree C. Raportul S:I = 1:4 ... 1:6, amestecarea fazelor si încalzirea se realizeaza cu gaze calde cu continut de SO<sub>2</sub>, care asigura, în acelasi timp, si regenerarea acidului clorhidric din solutia de iesire rezultând solutii de cloruri, din care elementele utile se separa prin precipitarea colectiva sau selectiva, obtinându-se subproduse utilizabile sau prelucrabile cu ajutorul instalatiilor metalurgice uzuale si reziduuri, din care, în cazul când au un continut ridicat de zinc, acesta se separa prin lesiere în autoclava sub presiune de oxigen, iar din solutii se separa sulfatul de zinc din care zincul se separa sub forma de sulfura prin calcinare si sulfurare.
