Before gravity separation, the manganese ore is first crushed (6-0mm or 10-0mm) and then classified. The coarse-grained manganese ore particles enter the jig for sorting; the fine-grained ore particles are sent to the shaker for sorting. Commonly used equipment includes gravity separators, spiral separators, etc.
