Grinding - Mineral Processing

The final fineness of the product mainly depends on the number of times the ore particles pass through the grinder. The longer the grinding, the smaller the particle size. Separate crushing and grinding steps are necessary, the ball mill can only receive the broken ore particle, and then grind to the grinding fineness required for flotation.

Six Factors Affecting Gold Cyanide Leaching Process

The grinding fineness is affected by the different ore characteristics, the size and form of gold particles. After carrying out tests on the -0.074mm content of 70%, 75%, 80%, 85% and 90% respectively, the mineral processing test personnel found that: When the part of -0.074mm accounted for 85%, the recovery rate of gold is better. When one-stage grinding fineness was increased from 70% to 85% ...
