Gold & Copper Mine Ball Mill Rubber Lining Mine ball mill lining are attached to ball mill metal body to enhance the milling process, we have two type which are gold and copper. A ball mill is a type of grinding mill, which purpose is similar to the sag mill or other mining crushers.
A two-stage grinding process forms a part of the comminution circuit. The grinding circuit comprises a 6.5MW SAG mill and 6.5MW ball mill. Using similar processes to the adjacent Cadia Hill concentrator, gold and copper are recovered in a conventional floatation circuit to produce a copper concentrate containing elevated gold levels.

The zinc-copper-lead ore will be processed into a concentrate, while we'll refine the gold-silver ore into semi-pure bars, called doré bars. During an average year, we'll produce 73,000 tonnes of zinc concentrate, 7,300 tonnes of copper concentrate, and 3,400 tonnes of lead concentrate. Also, we'll provide an average of 67,000 oz of gold.

The design of the 40-foot diameter SAG mill installed at the Cadia Gold Mine, New South Wales Australia, followed after two years of extensive laboratory and pilot plant testwork.
SAG mills are characterized by their large diameter and short length as compared to ball mills. The inside of the mill is lined with lifting plates to lift the material inside the mill, where it then falls off the plates onto the rest of the ore charge. SAG mills are primarily used at gold, copper and platinum mines with applications also in .
Jun 06, 2019· The mine produces several metal product streams. About half the gold that goes through the mill is captured in a precipitate and that goes to the Twin Creeks mine to be made into dorè bars.
The Oyu Tolgoi mine is in the South Gobi Desert of Mongolia, 80 kilometres (50 mi) north of Mongolia's border with the People's Republic of China, where the mined copper is expected to be shipped. Oyu Tolgoi deposits contain an estimated 2,700,000 tonnes of copper and 1.7 million ounces (48,000 kg) of gold.
