The entrance to the cyclone was designed this way to allow the incoming feed to help generate and not interfere with the spiral path that the ore must take inside the cyclone. The centrifugal force (the central Hydrocyclone Working Principle) that is generated by this spin, forces the "bigger particles outwards towards the wall of the …

For instance, at Lornex Mining, one of the most successful SAG installations, the ball load varies normally from 6-7% by volume of the mill; the ball make-up consists usually of 80% 4-inch diameter balls and 20% 5-inch diameter balls. The ratio of the larger balls is increased when the mill is processing hard ore and decreased with soft ore.

In this study, the extraction of gold from a copper-bearing gold ore by ammoniacal cyanide leaching was studied. Furthermore, ammonia leaching as a pretreatment process ahead of cyanide leaching was also examined. Only ~12% of gold was extracted by direct cyanide leaching of the ore. The addition of lead nitrate did not affect the leaching of gold.

Grinding tests were conducted on an oxidized copper-cobalt ore using a pear-shaped ball mill. Twelve mono-sized ore fractions were prepared and wet ground batchwise. The mill was run for 0.5 to 30 min intervals. The shortest interval provided data more closely related to the breakage function (B) because less secondary breakage was hypothesized.
