The influence of copper ore lithology on the grinding

The influence of copper ore lithology on the grinding

Oct 15, 2014 The main aim of laboratory tests was to find a relation between lithology of tested samples of ore and grinding media wear. Wear tests were performed in a laboratory mill filled with ball grinding media. Wet grinding was performed, which is typical for copper ore milling. Details of equipment used and tests data are presented Table 3

high pressure grinding rolls in gold treatment

high pressure grinding rolls in gold treatment

High pressure grinding rolls, also called roller presses, have been used in the treatment of iron ore, copper (Fig.), gold, diamond and various other ore types for many years. Contrary to conventional crushing rolls, the particles are broken by compression in a packed particle bed, and not by direct nipping of the particles between the two rolls

What is the difference between a SAG mill and ball mill?

What is the difference between a SAG mill and ball mill?

Attrition between grinding balls and ore particles causes grinding of finer particles. SAG mills are characterized by their large diameter and short length as compared to ball mills. The inside of the mill is lined with lifting plates to lift the material inside the mill, where it then falls off the plates onto the rest of the ore
