Gravity thickeners generally retain 80−90% of the solids in the thickened product stream, depending on the sludge characteristics and the efficiency of the preceding conditioning stage. The sludge characteristics also govern the solids loading rate (SLR), which is the rate in kg/d at which the sludge dry solids enter the process per unit process …

Autogenous (AG) and Semi-Autogenous (SAG) milling has seen increased use in recent years, especially in large mineral processing operations. These mills typically have a large diameter relative to their length, typically in the ratio or 2 or 2.5 to 1. AG mills employ ore as the grinding media. However, one the challenges with AG mills is that ...
