Potential cost savings measures. This study has found that in general the relative Mining and Milling costs of a given operation do not significantly differ, and generally fall within the range of 43:43:14 to 45:45:10 (Mine:Mill:G A). In addition, G A costs were found to be consistently lower than both Milling and Mining costs.
Grinding and Flotation. Fine ore at minus 19mm (¾") sizing is fed at a controlled rate into the opencircuit 2600mm x 3960mm (8'6 x 13'0) Hardinge rod mill at an average feed rate of 2,106 STPD or STRH.

The "mine of the future" could require much lower ball mill capacity for the same output based on grindcircuit roughing technology, reducing capital requirements, water usage, and CO 2 emissions. Likewise, sulfide leaching offers the possibility of an incremental, lowcapitalexpenditure approach to the development of lowgrade copper ...
The Kennecott Copper Mine has been a fixture of the Salt Lake Valley for over 100 years and on Tuesday, the mine announced it will be moving mining operations underground in its next step to extract copper. Rio Tinto will be investing 55 million in a section of its underground copper deposit known as the lower commercial skarns.
At the beginning of 1980s, the De Xing copper mine was the first to employ a SABC circuit in China. However, equipment failure during operation was frequent due to the lack of technical specialists in China to assist in circuit design and performance.
