Material with a copper grade over 0.40% is loaded onto rail cars and sent to the crushing circuit, where rotating crushers reduce the size of the rocks by approximately 85%, to less than onehalf of an inch. The ore is then sent to the rod and ball mills, which grind it in a mix with water to the consistency of fine powder.

Feb 03, 2012 · The SPEX model 8000 shaker mill has been used extensively for research on small batches of power (~10 cc), especially in the U.S.A (Fig. 3). This high energy ball mill agitates the charge of powder and balls in three mutually perpendicular directions at approximately 1200 rpm. It is highly energetic compared to the attrition and vibratory mills.

Ore from the mine has an average copper grade of 0.49% and an average gold grade of 0.39g/t. Crushed ore is further reduced in size by SemiAutogenous Grinding and ball mills. Once milled it is sent through a flotation circuit which produces a concentrate with a grade of 32% copper and 19.9g/t gold. The mill realizes a copper recovery of 89%.
