Ore Dressing Bauxite Methodology

Concentration or Dressing of Ore Study Page

Chemical Method. In this method the ore is treated with a suitable chemical reagent which dissolves the ore leaving behind insoluble impurities. The ore is then recovered from the solution by a suitable chemical method. This is applied for extraction of aluminium from bauxite Al 2 O 3.2H 2 O.

Notes OCCURRENCE AND EXTRACTION OF METALS

16.2.2 Concentration or Dressing of the Ore Generally 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.

Concentration and dressing of the ore Physical Methods

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.
