(i) Dressing of the ore is an essential process in the extraction of metal from its ore. Answer: 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.
