Zinc ore occurs in two types of deposit: as primary zinc ore in thin veins known as rakes, or a secondary deposit formed by weathering of the primary mineral veins. Zinc ore is most commonly found as zinc carbonate (ZnCO 3), known as calamine or smithsonite. It generally occurs as rounded, crystalline crusts or granular, honeycombed masses that ...
The low concentrations of the zinc sulphide mineral in most zinc ores mean that the ore must first be concentrated before extracting the metal The zinc blende (sphalerite: zinc sulphide)is first crushed to powder and then treated by froth flotation (that process is described in the copper unit. It is used in the extraction of several metals).
Zinc Essential Chemical Industry. However, any iron sulfide present in the ore will be converted to iron(III) oxide, which reacts with zinc oxide to form zinc ferrite In the simple leaching process, this zinc cannot be easily recovered and so ores with low iron content are preferable.

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 furnace with the flue gas and be lost, unless specific ...
Copper-Lead-Zinc ores The Cu-Pb-Zn separation process is among the most challenging flotation separations primarily because the first step must entail bulk flotation of the two most readily floatable minerals with these two minerals separated in a differential flotation stage.
