Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point. At temperatures typically used for smelting metals, zinc is a gas that will escape from a

the solution during the dissolution of ore, precipitate because of the high pH of the solution. Besides, am-monia forms stable complexes with copper ions, and this can lead to an increase in the dissolution rate of copper from ore. Thus, ammonia allows for

Flotation Of Zinc Oxide Ore Solution For Ore Mining Method for the recovery of oxidized lead and zinc minerals from ores at present is flota-tion (onal g. et al., 2005). the flotation of oxidized lead and zinc minerals, particularly zinc minerals, is much more difficult than the flotation of corresponding sulfide miner-als. hexyl and amyl xanthates are capable of collecting smithsonite.

Zinc processing - Zinc processing - 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
