History Miners at the Tamarack mine in Copper Country, in 1905. The Old Copper Complex in North America has been radiometrically dated to 9500 BP—, about 7480 BCE—making it one of the oldest known examples of copper extraction in the world. The earliest evidence of the coldhammering of native copper comes from the excavation at Çayönü Tepesi in eastern Anatolia, which dates between ...

Let's compare! Rubber Liners are better for abrasion grinding ie: cascade action but not for cataract mills. The graph below shows the increased operating cost of rubber and steel liners as the grinding ball size increases. Larger mill, larger ball. increases the cost benefit of using steel only mill liners. Looking at this chart, any time ...

Ball mill Most ball mills, even in primary applications, have a finer ore feed size; this requires some impact but not enough to increase the media consumption or even break the liners. Typically, a ball mill lining has a more rounded profile, often like a sine wave, and the size of the waves is selected based on the size of grinding media used.

Matte consists of base metal sulphides (cobalt, copper, iron and nickel). Matte serves as a collector for the PGMs [6, 7, 14]. Operating temperature of matte and slag varies with the composition of the concentrate . Typical smelter operating temperature for matte varies from 1380 to 1600°C, and that of slag varies from 1500 to 1680°C .

For the mining industry, our semiautogenous (SAG) grinding mill uses a minimal ball charge in the range of 615 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.

The ball mill liners are located on the inner surface of the ball mill barrel, which protects the barrel from the direct impact and friction of the grinding media and the material. The ball mill liners' material and shape are different base on requirements. When the grinding media contacts different shapes of ball mill liners, the movement state will also change, thus enhancing the crushing ...
