The crushed ore is transferred to a grinding mill, which contains heavy-duty steel balls or rods. As the mill rotates, the balls or rods crush and grind the ore, resulting in the formation of a fine powder. The purpose of crushing and grinding the gold ore is to liberate the valuable gold particles from the surrounding rock and minerals.
