selection of ore dressing method

Concentration or Dressing of Ore - Study Page

2021-2-26  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.

Concentration and dressing of the ore, Physical

Concentration or dressing of the ore: The ore are usually obtained from the ground and therefore contained large amount of unwanted impurities, such as rocky matter, earthing particles, sand, limestone etc. These impurities are known collectively as gangue or matrix.It is important to separate the large bulk of these impurities from the ore to avoid bulk handling and in subsequent fuel costs.
