Gold ore mining processing plant. Gold ore processing plant is widely used in gold ore crushing and grinding process to resize and pulverize gold ores into 10mm to smaller than 1mm particles. As gold ore's VHN hardness is between 60 and 105, SBM design gold ore crushing plant and grinding machine that can process gold ore.
After all the planned levels have been blasted, then all of the ore is removed for processing. This method is very selective and keeps dilution low, but requires many active stopes because ore is not removed from each mining area until completion – meaning longer lead times for ore to get to the process plant compared to cut and fill operations.
