Get PriceHighgrade ore deposits are depleting fast. Consequently, the mining industry has to take on lowergrade deposits, which are more difficult to extract. These deposits require the mining, movement and processing of larger volumes of material per ton of valuable mineral. The transportation, comminution and processing of these large volumes is expensive and energy intensive. These lowgrade ore ...
