A Novel Technology for Separating Copper, Lead and Zinc

First, the copper-lead-zinc mixed concentrate obtained by bulk flotation was oxidizing roasted to remove S in the concentrate, i.e., after oxidizing roasting, most sulfide in the concentrate was transformed to oxide, which was beneficial to leaching. Through the leaching of sulfuric acid, the complex and difficult-to separate copper-lead-zinc

In this work, oxidizing roasting was combined with leaching to separate copper, lead, and zinc from a concentrate obtained by bulk flotation of a low-grade ore sourced from the Jiama mining area of Tibet. The flotation concentrate contained 7.79% Cu, 22.00% Pb, 4.81% Zn, 8.24% S, and 12.15% CaO; copper sulfide accounted for 76.97% of the copper, lead sulfide for 25.55% of the lead, and zinc
