Abstract
Procedeu de obtinere a concentratelor cu continut ridicat de molibden, din concentrate sarace de molibden cu continut de Cu, Pb, Zn, Fe si 20...40% minerale insolubile în acizi. procedeul, conform inventiei, realizeaza flotatia la pH=7,5...8,6 în prezenta de colector si spumant uzual, Cu, Pb, Zn, Fe si minerale insolubile fiind depresate, folosindu-se pentru depresarea Cu, Pb, Zn, Fe, adaosuri uzuale de silicat de sodiu, hipoclorit de sodiu, sulfura de sodiu si cianura de sodiu, iar pentru depresarea mineralelor insolubile în acizi un adaos de 3...10 kg/t concentrat solutie de bisulfat de amoniu 3...20% concentrat. Se obtine astfel un concentrat cu continut de 50...55% Mo, Fe total 0,5...3%, insolubile în acizi 4...7% si maximum respectiv 0,2% Cu, 0,2% Pb si 0,2% Zn.
