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 results indicate that higher mill speed and lower ball load operating strategies are preferable with respect to energy savings in variable speed ball mill operations. Ore characteristic variations at the Copper Mountain Mine are significant and can cause large oscillations within mill operations.
Toquepala is a porphyry copper mine located in the Peruvian Andes mountain range. It is mainly rich in copper, molybdenum, silver with minor gold and zinc deposits.

The very large, very low grade Highland Valley Copper (HVC) mining complex in south-central British Columbia is not only Canada's largest metal mine, but is also globally significant. In 2004 it produced 1.4% of the …
Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today's compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it's roasted, which helps to convert sulfides to oxides. The oxides are smelted to produce matte, which then …
Orovalle Minerals S. L. operates a copper/gold mine in the Asturias region of northern Spain, with the operation dating back to December 1997. The feed to the El Valle mill, consisting of oxide/sulphide (skarn) mineralization, is highly variable, even on a shift by shift basis and presents challenges to the mill operating staff on a daily basis.

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
