The extent to which fine crushing can be carried out will vary and depends on the ore characteristics, plant and crusher design. Unfortunately, the ore characteristics are generally beyond our control, so the concentration of effort lies primarily on the plant arrangement, equipment design and operation.
The manganese ore process is used to beneficiate manganese oxide and carbonate ore. Pre-separation: usually includes crushing and grinding to reduce the size of the ore particles; sometimes a washing process is also used to effectively remove impurities such as soil and clay adhering to the surface of the manganese ore.

Using a gold wash plant, exposed gold-bearing gravels are mined using a bulldozer that pushes and stockpiles the gravel near a wash plant. The stockpiled gold-bearing gravel is then fed into the wash plant by a front-end loader or large backhoe. This practice promotes equipment efficiency by allowing the bulldozer to continue mining while the loader or backhoe feeds the …
