Outotec says it has signed a services contract for the delivery of four ball mill upgrade packages to a copper and gold mine in Asia Pacific, which has a value of €19 million ($21.4 million). Refurbishment projects for older, existing assets are an efficient method to extend a mill's operating life, increase energy efficiency and ...
The "mine of the future" could require much lower ball mill capacity for the same output based on grind-circuit roughing technology, reducing capital requirements, water usage, and CO 2 emissions. Likewise, sulfide leaching offers the possibility of an incremental, low-capital-expenditure approach to the development of low-grade copper ...
At the Sarcheshmeh copper mine 41,000t of ore per day with an average grade of 0.9% Cu is ground to 70% passing 75 microns. Grinding is effected in 8 parallel lines of 8x5m ball …

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.
water usage. The crushed ore is transferred to a semiautogenous (SAG) mill or ball mill where the ore is further reduced in size. Water is added to the ball mill, in which a slurry that usually contains from about 20 to 55 percent solids is produced (Singh, 2010; International Mining, 2011) (see fig. 2). The

The Copper Mountain mill flowsheet is currently a conventional two-stage crushing, semiautogenous grinding (SAG), pebble crusher, ball milling and sulphide flotation circuit design.
Reason: This is a common problem mining ball mills face, resulting in low productivity and low ore processing efficiency. One reason may be the improper design of the grinding chamber, which affects the flow of materials and reduces grinding efficiency. Additionally, worn or damaged liners can hinder the grinding process by reducing the …
