The Grinding Fineness- the Factor Affecting Gold Leaching

2020-3-25  With the increase of the grinding fineness, the gold leaching rate increases first and then slowly. It can indicate that increasing the grinding fineness is beneficial to release of gold minerals from the inclusions. Take into comprehensive consideration, a 325 mesh accounted for 95% is a more suitable gold leaching grinding fineness.

Grinding Mineral Processing

The final fineness of the product mainly depends on the number of times the ore particles pass through the grinder. The longer the grinding, the smaller the particle size. Separate crushing and grinding steps are necessary, the ball mill can only receive the broken ore particle, and then grind to the grinding fineness required for flotation.

Guide of the Overage Grind of Ball Mill Xinhai

2019-9-18  The harm of overage grind mainly includes two aspects: 1. The problem of overage grind will make the ball mill reduce or even lose the grinding effect on the ore, and destroy the stable work of the ball mill. Meanwhile, dealing with the overage grind will also affect the ore quality fraction and grinding fineness of the subsequent separation
