Gravity concentration process is the oldest beneficiation method known to mankind. This is a physical process and exploits the differences in densities of minerals to bring about a separation. Although with the advent of froth flotation, the relative importance of gravity concentrat-ion has declined in twentieth century but still on an average higher tonnage of material is treated by gravity ... Oct 09, 2020 This is a chemical method of concentration. In this method the powdered ore is treated with a suitable reagent that dissolves the ore but not the impurities. The impurities left un-dissolved are removed by filtration. Leaching method is used for concentrating ores of aluminium, silver, gold,, etc. For example, bauxite ore containing iron oxide ...

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. ore, it is not possible to have any one set procedure applicable to all samples. It is often necessary to combine two or more methods to effect the dissolution of an ore. There are mainly two methods to open an ore. They are (1) wet method (2) dry method. Wet method constitutes the digestion of an ore sample with an acid or a
