 · Conventional grinding using a rod mill or ball mill will also be used, or some combination, to grind the ore to fine powder (micron size) using rods, balls, with the ore in the SAG mill to assist

 · This is a way to control overgrinding as well as to achieve the appropriate grain size to liberate the gold. 1 As no information is available about the optimal grain size for a given ore, testing different grinding times is the only way to obtain such information. Concepts like the following can be passed to the miners, who can use a small ball mill and gravity separation …

For the mining industry, our semi-autogenous (SAG) grinding mill uses a minimal ball charge in the range of 6-15 percent. It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. Autogenous (AG) grinding mills involve no grinding media as the ore itself acts as the grinding media.

Higher mesh numbers = smaller particle sizes. It is very important to remember that mesh size is not a precise measurement of the mesh opening size. This is because screens can be made with different materials with different thicknesses of strands or wire. The thicker the strands, the smaller the openings that a particle can pass through, and vice versa. Also keep in mind that …
