Methods of Ore Pretreatment for Comminution Energy ...

The comminution of ores consumes a high portion of energy. Therefore, different pretreatment methods of ores prior to their comminution are considered to reduce this energy. However, the results of pretreatment methods and their technological development are stered in literature. Hence, this paper aims at collating the different ore pretreatment methods with their appliions and results ...
