The treatment of the Gacun complex Cu-Pb bulk concentrate with high Zn, Ag, etc., by oxygen pressure acid leaching was studied. The primary copper and lead minerals in the concentrate are tetrahedrite and galena. The treatment of tetrahedrite was rarely studied, and most of silver occurred in the mineral too. The optimum operating parameters of oxygen pressure acid leaching were established by ...
Abstract In this paper, the leachability of lead and cadmium from cementitious waste was investigated to determine the leaching mechanism of these heavy metals from a cement matrix so that a more a...

The present paper deals with the mineralogical and flotation characteristics of two lead-zinc ore samples (S1 and S2) from Ganesh-Himal region of Nepal. The two samples assayed 2.47% & 3.53% Pb and 13.6 & 13.45% Zn respectively. The ore was predominantly made up of spahlerite and pyrite in association with subordinate amounts of galena, minor amounts of pyrrhotite and chalcopyrite.
