Concentration or Dressing of Ore
The ores are found mixed with earthy impurities like sand, clay, lime stone, etc. These unwanted impurities in the ore are called gangue or matrix. The process of removal of gangue from powdered ore is called concentration or ore dressing. There are several methods for concentrating the ores. The choice of method depends on the nature of the ore.
