Sulfidation of Oxidized Lead and Zinc with Pyrite-Bearing Lead-and-Zinc Ore
The joint roasting of lead-and-zinc ore and sulfide ore initiates generation of sulfur-containing agents and sulfidation of rebellious oxidized lead and zinc. It is experimentally proved that selective oxidation of pyrite proceeds together with disintegration of lead and zinc along the interphase boundaries.
