Gold processing Mining, Concentrating, Refining: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (, 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for extraction by ...

The problem with ball mills is that they can be very heavy and expensive. A small flowthrough ball mill like the one above would do nicely in a small hard rock gold mill that processes finely divided gold from a high grade ore. An older, used ball mill, of about 2×4 foot will set you back from 4,000 to 5,000.

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
