The concentration of ore is a method of eliminating gangue particles or other impurities. ore-dressing and benefaction are the alternative names for the term concentration of ore.
To obtain a pure metal from ore, the method of ore concentration is a very crucial step. for the extraction of metal, it is necessary to separate ore from the gangue particles. ore found in the earth contains many impurities like sand, grit, rocks etc. which are collectedly known as gangue.
The concentration of ore is the first step of metal extraction. there are different types of ore like native, oxidized, sulphurized and halide which can be concentrated by various physical and chemical methods.
The concentration of ore can define as the chemical process of eliminating impurities like sand, rocks, silt, grit etc. from the ore for the extraction of metal. in simple words, the concentration of ore is the method of separating ore from the gangue, as the gangue or matrix are the valueless substances that are of no use.
The ore can be concentrated or separated by both physical and chemical means. the ore which is obtained after the completion of the ore concentration will refer as concentrate.
Ore can define as a solid substance like a rock which contains minerals or combination of minerals from which the metal can be extracted by a series of methods like the concentration of ore, isolation of metal and refining of metal.
Native ore these are the type of ores which are non-reactive and contains metal in a free state.
Oxidized ore these contain oxides or oxysalts, i.e. carbonates, phosphate and silicate of metal.
Sulphurized ore these contain sulphides of metal like iron, lead etc.
