    Firstly, it involves the preparation and liberation, of the valuable minerals from waste minerals and secondly, the separation these values into two or more products, called concentrates. The term separation in this case is synonymous with concentration. These functions are carried out within the constraints of the following

    Preconcentration signifi cantly improves the value of the resource by upgrading below cutoff grade material and/or increasing production rates per tonne of material treated. There are several technologies that may be applicable for preconcentration including: gravity processes, magnetic separation, sensor based ore

    Aug 11, 2017 Most minerals are a combination of metal and other elements. The rocks that are taken from a mine are full of valuable minerals plus rock that isn't valuable. This is called waste rock. The valuable minerals must be separated from the waste rock. One way to do this is with a chemical reaction. Chemicals are
