A Novel Technology for Separating Copper, Lead and Zinc

Jun 18, 2019 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

Liquation - Wikipedia

Liquation is a metallurgical method for separating metals from an ore or alloy.A mixture of metals is melted together with a third, after which the mixture is separated by liquid extraction.This method was largely used to separate silver from copper using lead, but it can also be used to remove antimony minerals from ore, and refine tin
