Zinc smelting

Zinc smelting is the process of converting zinc concentrates 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 measures are taken to prevent it. The most common zinc

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).
