Abstract Modeling of some parameters of wet ball milling system of copper sulphide ore was performed in this study. A three level Box–Bhenken design combining a response surface methodology (RSM) with quadratic model was employed for modeling of key operating parameters of ball mills. Grinding experiments were designed and executed by a laboratory ball mill, considering ball size, ball

Copper Flotation

16-05-2016Porphyry copper ores, usually medium to medium hard, require grinding to about 65-mesh to economically liberate the copper minerals from the gangue. Although a clean rougher tailing can often be achieved at 65-mesh the copper mineral is not liberated sufficiently to make a high grade copper concentrate, thus some form of regrinding is necessary on the rougher flotation copper

Ball Mill

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.

Mining Technology in the Nineteenth Century

The development of cyanide milling at the end of the nineteenth century required grinding into smaller and more uniform sized particles using Chilean mills, ball mills, and tube mills. After crushing or grinding, miners often used vibrating or shaking machines called concentrators (e.g., jigs, buddles, vanners, Embrey tables, and tables) to separate heavier metal-bearing ores from gangue.

How copper is made

Most of the copper ores mined in the United States contain only about 1.2-1.6% copper by weight. The most common sulfide ore is chalcopyrite, CuFeS 2, also known as copper pyrite or yellow copper ore. Chalcocite, Cu 2 S, is another sulfide ore. Cuprite, or red copper ore, Cu 2 O, is an oxide ore.
