• Zinc processing - The zinc-lead blast furnace | Britannica

    The zinc-lead blast furnace has the flexibility to accept a wide range of mixed ores and residues in its feed. Complex sulfide ores have to be sintered, but oxidized residues such as zinc ashes and drosses recovered from galvanizing processes, oxides produced from low-grade residues, lead smelter dusts, and steel-mill dust high in lead and zinc can bypass the sinter roasting process.

    Polymetallic vein and replacement deposits are characterized by elevated abundances of Pb-Zn±Cu±Au±Ag±Mo±As ± Bi±Sb. In some districts, ore proximal to igneous intrusions is copper and gold rich, and grades laterally (and sometimes vertically) into lead-zinc-silver-rich ore. A distal, manganese-enriched zone is present in some districts.

  • Zinc Mining and Processing: Everything you Need to Know

    The zinc mining process is conducted primarily underground, with more than 80 percent of all zinc extracted beneath the Earth's surface. Eight percent of zinc is mined in open pits, with the remaining 12 percent being mined through both methods. Once it's removed from the earth, the concentrate is roasted at a temperature of 950 degrees Celsius, causing zinc, sulfur and iron oxidization

    Gold is an easy-floating mineral, so extraction of gold by flotation process has always been one of the effective ways to process gold-bearing ores. In primary gold deposits, gold minerals often coexist with sulfide minerals such as pyrite, chalcopyrite, galena, and sphalerite. These minerals are both easy-floating minerals and form stable mineralized foams. They are the ideal carrier minerals
