Mill leaching: a viable substitute for mercury

2009-10-1  For batch grinding, the artisanal ball mills are ideal for cyanide leaching. The mill-leaching process was successfully implemented in Portovelo, Ecuador. About 95% of the gold was leached from a pre-concentrate (with 17.3 g Au/tonne) obtained by grinding the ore in Chilean mill and concentrates gold in sluice boxes.

The Role of Gravity and Intensive Cyanidation in

A flow sheet has been developed to treat a high tonnage highly preg-robbing gold ore. The ore is low grade and fine grained with a high proportion of very fi ne free gold. The key components of the flow sheet include gravity, flotation, intensive cyanidation with direct electrowinning, and carbon-in-leach of the flotation concentrate. The circuit produces a low overall mass pull to

Generally ball mills are utilized after an initial material crushing or grinding has occurred. Thus, a disadvantage of the ball mill is that the feed size must already be small.
