اقرأ أكثرGrinding is done in cylindrical steel vessels known as tumbling mills. These contain a charge of loose crushing bodies known as the grinding medium which is free to move around inside the mill, thus breaking the ore particles smaller. Grinding medium can be steel rods or balls, hard rock or the ore itself. Milling circuits vary from mine to mine.

اقرأ أكثرImmediately following extraction, ore crushing and grinding, known as comminution, takes place. This reduces ore to manageable sized particles and releases its valuable components while discarding non-valuable ore, called gangue. For effective comminution, large-sized ore is crushed in a crusher developed for this specific process, and the ...
