Ball Mill For Gold. A Ball Mill a type of grinder is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball Mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium.

If the cyclone underflow gold grade was higher than the cyclone overflow grade then you have free gold and you should look at putting a centrifugal concentrator in the grinding circuit. For low tonnage operations you can feed of the ball mill discharge to the concentrator (this requires an extra pump, but is worth the effort).
