This method has been used for the concentration of sulphide ores, such as galena (PbS), zinc blende (ZnS), copper pyrites (CuFeS 2), etc. The sulphide ore particles are preferentially wetted by oil and gangue particles by water. a) In this method, the powdered ore is mixed with water to form a suspension in a tank.

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.

The first step in metallurgy is to remove these unwanted impurities from the ore, to get a concentrated ore containing a much higher percentage of the metal. The method used to remove gangue from ore depends on the physical or chemical properties of the gangue and ores. Some of the methods used in the concentration of the ore include, 1.

Copper ore beneficiation methods. Before the beneficiation of copper ores, crushing and grinding are required. The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.15-0.2mm.
