2021-6-20 In simple words, the concentration of ore is the method of separating ore from the gangue, as the gangue or matrix particles are the valueless substances that are of no use. The ore can be concentrated or separated by both physical and chemical means. The ore obtained after the completion of the ore concentration

2021-6-17 Ore concentrate, dressed ore or simply concentrate is the product generally produced by metal ore mines. The raw ore is usually ground finely in various comminution operations and gangue (waste) is removed, thus concentrating the metal component. The concentrate is then transported to smelters where it is used to produce useful metals.

6. Separation and concentration. Following milling, the ore is subjected to different processes according to its nature. Pulp may require to be thickened ahead of these processes in large tanks called Thickeners, in which the solid component is allowed to settle and is raked towards the centre by large, rotating rakes while relatively clear water overflows into a peripheral drain or Launder.
