Comminution is the most energy consuming process in mining industry, where nearly 60 of the electricity expenditure is due to grinding purposes. In the nature most of the ore minerals are found, finely disseminated and intimately associated with the gangue, thus, liberation is the main target to recover these minerals. In order to optimize the size reduction process, the correct prediction ...
