However, gold is produced in much smaller quantities, so the total environmental footprint for global gold production is smaller than some other commonly used metals, including steel, copper and aluminium. The stages that contributed the most to gold’s environmental impact were mining and comminution (crushing and grinding of the ore).

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.
