Gold recovery from copper-zinc ores is usually higher than that obtained from either a lead-zinc or copper lead-zinc ore.This is attributed to two main factors: when selecting a reagent scheme for treatment of Cu-Zn ores, there are more choices than for the other ore types, which can lead to the selection of a reagent scheme more favourable for gold flotation

Ores. Zinc ores are widely distributed throughout the world, although more than 40 percent of the world’s output originates in North America and Australia. The common zinc-containing minerals are the zinc sulfide known as zinc blende or sphalerite (ZnS), a ferrous form of zinc blende known as marmatite [(ZnFe)S], and a zinc carbonate known as calamine or smithsonite (ZnCO 3)

Sphalerite, which is a form of zinc sulfide, is the most heavily mined zinc-containing ore because its concentrate contains 60–62% zinc. [19] Other source minerals for zinc include smithsonite (zinc carbonate ), hemimorphite (zinc silicate ), wurtzite (another zinc sulfide), and sometimes hydrozincite (basic zinc carbonate ). [21]

Jun 26, 2021 The principal ore of zinc used for its extraction is Zinc blend ( Z n S). As Zinc blend is a sulphide ore, the process used for its concentration is the Froth Floatation Method. The concentrated ore is then roasted in excess air at 1200 K to obtain zinc oxide ( Z n O). It is then reduced to Z n by coke at a temperature of 1673 K
