Richards gives the average amount of water used in 21 mills as gallons per stamp per minute, or tons of water per ton of ore crushed. The average duty of a miner's inch in a gold stampmill is given by P. M. Randall as 12 tons of quartz if the head under which the water is supplied is 4 inches, and tons if the head is 7 inches.

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.

Optimizing Regrinding Capacity. The justification, for including regrinding of a concentrate or middling in the design of any new copper flotation plant, should be that a greater economic return (by any preferred, economic criterion) will result thereby than is obtainable at any fineness of primary grind, without regrinding.

The Gold Mining Process. In addition to cyanide processing, gold ore is also processed with gravity separation. Advanced technology has enabled the amount of gold mined and processed to steadily increase over the years. For example, the worldwide production of gold in 2006 was 2360 metric tons. As of 2013, that number had climbed to 2770 metric ...
