Steps involved in the concentration of ore- roasting, calcination, and smelting
Steps involved in the concentration of ore:
Roasting:
- Roasting is a process in which the ore is heated in the presence of air to remove moisture and other volatile impurities.
Calcination:
- Calcination is a heating process used to remove impurities from the ore and to prepare it for smelting.
Smelting:
- Smelting is the process of extracting a metal from its ore by heating the ore to a high temperature in the presence of a reducing agent.
