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.

The gold ore straight from the mine gets fed into a jaw crusher first. This big machine breaks down the huge rocks into smaller pieces, usually around 100-200 mm in size. After that, the crushed ore moves to the secondary crusher, which is usually a cone crusher. Here, it gets crushed even more, down to around 10-50 mm.
