It is also found with deposits of other metals, such as zinc, silver, copper, and gold. Lead is essentially a coproduct of zinc mining or a byproduct of copper and/or gold and silver mining. Complex ores are also the source of byproduct metals such as bismuth, antimony, silver, copper, and gold.
Escondida copper, gold and silver production. Production at the mine was cut back during the period 2003 on account of the weak world market conditions for copper. The partners in the project decided to mine lowergrade ores while maintaining the concentrator throughput, thus reducing the impact on pertontreated costs.
Ball mill. A typical type of fine grinder is the ball mill. SAG mills are primarily used at gold, copper and platinum mines with applications also in the lead, zinc, silver, alumina and nickel industries. Pebble mill. A rotating drum causes friction and attrition between rock pebbles and ore particles.

Copper Mining and Processing: Processing of Copper Ores. ... Following mining, transporting, and crushing to a consistent gravel or golf ballsize, the crushed ore is further processed at a mill using secondary crushers, and reduced to pebbles, and finally to fine sand. After the copper ore is crushed, liquid is added to make it a slurry.

Number 12 (AWG) copper wire is the most common size used for branch circuit wiring in buildings. The amount of copper products consumed in the USA in a typical year would make a size 12 wire that could encircle the Earth 2,250 times or make 120 round trips to the Moon. Copper Fact 4
A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of …
Minetomill optimisation: effect of feed size on mill throughput No. 48 SRK ’s International Newsletter One of the most valuable aspects of blasting is the generation of very fine particles (, smaller than 12mm) that will pass through the primary mills and onto the secondary ball mill circuits, alleviating a common bottleneck.
Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced.
