Step #3 – Drill Testing/Samples. Next, rock samples are taken through drill testing and analyzed. Geologists and mining engineers use these samples to determine if gold actually exists, the size of the deposit and the quality of gold in the ground beneath. This information is used to determine if enough gold exists under the surface to make ...

Manufacturers tend to use rules of thumb to de-rate crusher capacities for the treatment of highly competent ores that display high Bond crushing work indices (CWi). One such rule is the following: de-rate = (16/CWi)^0.5. However, care is required when using this rule as CWi test methods vary and simplistic approaches do not address all of the ...
