The above pre-treatment stages can be changed based on ore mineralogy. For a complex Au–Ag ore, direct cyanide leaching resulted in only about 47% and 19% extraction of gold and silver even after very fine grinding at <38 µm.Diagnostic leaching was carried out to assess the nature of refractoriness [29].Depending on the results of the diagnostic test …
By the way, the larger the diameter of the ball mill, the lower the filling rate. For the rod mill, the filling rate is generally 10% lower than that of the ball mill of the same specification. 2.2 Diameter of steel grinding ball. The grinding efficiency is reflected in the processing capacity of the mill and the fineness of the grinding ore.
