Dry Type Ore Ball Mill
Gold extraction
Ball mills can operate in either wet or dry conditions. They are advantageous because they can achieve a very fine particle product size (refer to Table 1). Generally ball mills are utilized after an initial material crushing or grinding has occurred. Thus, a disadvantage of the ball mill is that the feed size must already be small. Table 2 outlines some typical ball diameters found in ball ......

Mineral Drying
Extracted ore, no matter the mineral, is typically first crushed, and then must go through a beneficiation process to remove the unwanted impurities. Beneficiation can vary significantly from one ore type to the next. In most cases, however, beneficiation is carried out through a wet process that necessitates a subsequent drying step. Mineral drying at this stage offers several benefits:...
