Based on the placement of lead and its consumption in industry branches, the paper deals with the composition of
lead in the massive of Kopaonik. Removal, tenuity and grinding of galenit. The paper in particular treats the flotation process.
Also treats physico-chemical bases of reagents in the process, as well as decanting, drying, filtering and storage of
concentrates. Verification of the chemical composition of Pb concentrates with Pb, Zn, Bi, As, Sb, In, Au, Ag, etc. It is special
that in Kopaonik massive the ratio of Pb: Zn composition is 1.4: 1.0 and during the flotation lead is inclined to go with
pirotines concentrate more than is allowed. We are strongly focused to maximally decrease the Pb amount that goes with
pirotine concentrates and wastes
