Lime is added to the ball mill for alkalinity control together with mill cyanide solution for dilution. About 75% of the recoverable values are usually dissolved in the grinding circuit. The overflow or pregnant solution from the primary thickener goes to the bag-type zinc dust precipitation unit for recovery of the values as a precipitate.
Mill operating conditions including mill speed (for circuits with variable-speed drives), density, and total mill load; The effect of feed hardness is the most significant driver for AG/SAG performance: with variations in ore hardness come variations in circuit throughput. The effect of feed size is marked, with both larger and finer feed sizes ...
The primary function of gold mining ball mills is to grind and crush ore materials to a fine powder.

Optimizing Primary Grinding Capacity. The relation of fineness of grind to the degree of liberation of the valuable minerals from the gangue is certainly a factor to be considered in optimizing the primary grind. This largely determines the grind-recovery curve and the point of maximum recovery, which is normally at a very fine grind.
Types of Grinding Mills. Grinding mills play a crucial role in the mining process, as they are responsible for reducing large chunks of ore into smaller particles that can be further processed. There are various types of grinding mills available, each designed to meet specific requirements based on the material being ground and the desired output.
