The 24 x 39.5 Ball Mill The Copper Mountain ball mills are 7315 mm 24 feet in diameter and 12040 mm 39.5 feet long. They are overflow discharge ball mills with inside diameters of 7315 mm 24 feet and grinding lengths of 11887 mm 39 feet. Each Ball mill is also driven by two 8,500 horsepower ABB motors.
Copper sulphide mineralisation occurs in quartz veins and in micro fractures, and most of the mineralisation is located in the central part of the property. The open pit mine is estimated to contain reserves of more than 301.5 million tonnes Mt grading at 0.359 copper and 0.274g per tonne g/t of gold. Mining and ore processing of coppergold

A crushing section is where the ore is crushed by primary, secondary and tertiary crushers to a final product size of 12mm with an 80 passing. Following the crushing section there is a wet grinding section consisting of a rod mill and ball mill, where the crushed ore is further reduced in size to facilitate flotation of the various minerals.
The Copper Mountain mill flowsheet is currently a conventional twostage crushing, SAG, pebble crusher, ball milling, and sulphide flotation circuit design. The current capacity supports 40,000 t per day of ore processing. The 45ktpd Expansion that is currently underway will add a third ball mill in parallel with the two existing ball mills.
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.
Titanium Ore in South Africa Titanium ore is abundant in South Africa and it is one of the most distributed in the crust. It accounts for 0.61 of the earth's crust and it is in the 9th position. After titanium, aluminum, magnesium, titanium ranks the fourth situation.
The ore then feeds to a ball mill before being discharged to the flotation circuit. The goldenriched copper concentrate will be piped to the filter plant for drying and the removal of water down to a moisture content of 10, according topany, while the tailings will be segregated to pyrite and nonpyrite streams before being
Figure 1 Geographic Location of the Impala Projects and Interests in South Africa UG2 Ore UG2 ore is the second most mined source of PGE in theplex. Located in a reef close to and largely parallel to the historicallymined Merensky Reef, UG2 has always been an enticing source of PGE, but metallurgical difficulties delayed its
