Process. As shown in Fig. 1, the beneficiation process mainly comprises the sub-processes of grinding, separating and dewatering. 2.2.1 Grinding Grinding is a sub-process of finely grinding ore in advance, such that the ground output can be physically separated into iron ore and impurities in the downstream sub-process. In many cases, an.Beneficiation is the technical term describing the industrial process of mechanically separating minerals from each other. No chemical changes to the minerals are made at this point in the mining process.
