Crushing Plant Flowsheet & Design-Layout. In the crushing section, the ore as it comes from the mine is broken down dry to a size suitable for the wet grinding machines ; these can, if necessary, be made to take lumps of 2-in. size, but they work much more efficiently if their feed is ½ in. or less. Before the advent of the cone …

Rich ore containing more than 3% nickel can be directly smelted; ore containing less than 3% nickel needs to be processed. 's beneficiation method in processing copper-nickel sulfide ore is mainly …

1. Crushing equipment. A columnar rock often accompanies nickel ore with incomplete weathering. The block size may exceed 1m. If you don't crush them, only use the original ore bin to control the ore size.

Washing of run-of-mine ore can be carried out to facilitate sorting by removing obscuring dirt from the surfaces of the ore particles. However, washing to remove very fine material, or slimes, of little or no value, is more important. Washing is normally performed after primary crushing as the ore is then of a suitable size to be passed over ...
