Abstract
Procedeul prevede clasarea granulometrica a materiei prime la proportia de 80% clasa - 3 mm, urmata de tratarea acida a acesteia cu solutii de 250...350 g/l H2SO4 la o temperatura de58...85 degree C. Solutia obtinuta cu 520..620 g/l Al2(SO4)3, 4...10 g/l Zn, 0,11...0,40 g/l Cu, dupa purificare cu solutii 10...30% Na2S sub depresiune, se supune cristalizarii izohidrice. Produsele rezultate din proces sunt: un produs zincos cu continut cu continut de 50% Zn, 30% S, 4...5% Fe si, respectiv, sulfatul de aluminiu hidratat cu 15,8...18,0% Al2O3, care se încadreaza calitativ în cerintele STAS 342-80. Randamentele globale de extractie metalica sunt. Al2O3=86%, Zn=90%.
