So nearly all rocks on the planet have some metal or mineral content However, the concentration of this metal is too less for it to be valuable Ores usually have a very high content of the desired mineral, but it still must be separated from other mixed impurities, This method is known as the concentration of or
Concentration of ores is important industrial processes and is the first steps to the extraction of the metals Normally, the ore is concentrated by separating it from the clay body in which it occurs either by gravity, sedimentation, or by a floatation process, before the extraction of the metal from the ore ,
