Steps involved in the concentration of ore- roasting, calcination, and smelting

 Steps involved in the concentration of ore:

DIFFERENCE BETWEEN ROASTING,CALCINATION_SMELTING

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.
