The mine consists of two pit operations and a concentrator plant. The concentrator plant, which consists of a semi-autogenous grinding (SAG) mill and two ball mills, can process 70,000 tonnes of copper sulphide ore per day using crushing and rotation. Concentrate is thickened and filtered at the mine before trucking it to the port for export.
A stamp mill consists of a set of heavy steel (iron-shod wood in some cases) stamps, loosely held vertically in a frame, in which the stamps can slide up and down. They are lifted by cams on a horizontal rotating shaft.As the cam moves from under the stamp, the stamp falls onto the ore below, crushing the rock, and the lifting process is repeated at the next pass of the cam.

Ball mill. A typical type of fine grinder is the ball mill.A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.

Copper ore, in concentrations ranging from 0.29 percent to ten times that amount, is mined from open pit or underground mines. The crushed mine ore is ground in rod and ball mills and then sent to flotation machines where the copper mineral rises to the top in a froth, making a copper concentrate of approximately 30 percent, 27 percent iron and 33 percent sulfur.

Jun 25, 2019· The world's 20 largest copper mines produce nearly 9 million metric tons of the precious metal a year, about 40 percent of the world's total copper mine capacity. Chile and Peru, alone, account for about half of the copper mines on this list, but the U.S. does make the cut, with two mines among the top 20.
When the rocks are about 3/8-inch or smaller, they are fed as a slurry into the two ball mills. Each ball mill is turned by a single 3,000 horsepower electric motor. These mills contain literally hundreds of thousands of three-inch diameter steel balls that pulverize the ore until it is like fine sand or face powder. Only then are the copper ...

Over the past 15 years, mine-to-mill studies have focused attention on the impact blast fragmentation has on concentrator throughput. Blasting provides the first opportunity for comminution – or size reduction. It is also a cheaper and more efficient process, compared to both crushing and grinding.
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.
