Oct 01 2009 One mill grinds 40 kg of ore for 4 h using 40 river pebbles 510 cm or steel balls. The grinding step is then interrupted and 0.51 kg of mercury is added per mill. The mill runs for an additional hour. Each mill processes 400 kg of ore before the gold amalgam is removed. The ground product is mostly finer than 150 mesh 0.105 mm.
