Understanding the SAG Mill in Copper Ore Mining Process
This machine uses steel rods as the grinding media instead of balls, which are commonly used in ball mills. The rods grind the ore by tumbling within the mill, similar to the action of a rotating drum. Rod mills can be operated at lower speeds than other types of mills, making them ideal for fine and coarse grinding applications.
Process of steelmaking
Iron ore has a sand-like structure that can put out the fire in the furnace. Because of that, you can't put it in the furnace just like that. The ore is first baked to make it into porous chunks, or sinters. This is done in the Sintering Plant. In the Pelletising Plant, we turn the fine ore into small balls in large drums.
