The gold contained in the ore occurs at an average of. 17 opt (ounces per ton of ore). The gold is within the sulfide mineral matrix, which is not exposed (and therefore can not be dissolved by) a cyanide leach solution. Also the ore contains carbonaceous matter which absorbs gold in the conventional leaching process.

The gold mining process is gaining momentum. Those boulder-sized chunks are now manageable. They're progressing along a conveyor line and entering a mill. It's in here that water and steel balls smash into the ore-containing rocks until they're nothing more than a soup made of gold, grit, and water.


Stackers for Mining. Reducing dust from Stack-Out operations can be challenging. The elevation of the Stacking conveyor above the discharge point is a major factor in how we approach the problem. Solutions can include using a combination of the following measures: Dry Fog™, Wet Suppression, Strip Curtains and DustTamer™ Wind Fence Systems.
