## Zinc is extracted from which ore

Apr 23, 2021

The extraction of zinc from zinc blende involves the following steps. Concentration: The ore is crushed and then concentrated by froth-floatation Process. Reduction: Zinc oxide is mixed with powdered coke and heated to 1673k in a fire clay retort in which ZnO is reduced to zinc metal. ZnO+C →1673KZn+CO

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
