Maximum recovery of sulphide minerals by flotation is achieved over a limited size range. Valuable particles above and below this range have a smaller probability of being recovered. In the normal grinding-flotation operation, not all valuables are reduced to the optimum size range, and therefore sub- stantial losses occur. A significant improve- …

Precision grinding is the process of removing metal from a workpiece to achieve a specific size, shape, or surface finish. Surface grinding is a type of precision grinding that is used to create flat surfaces on metal workpieces. This process involves using a grinding wheel to remove tiny bits of material from the surface of the workpiece until it is smooth and flat.
