At present, the process of manganese oxide ore dressing in China is generally to crush the ore to 6~0 mm or 10~0 mm, and then the coarse-grade for jigging, and fine-level for tabling dressing. It is essential to recover as much manganese as possible in the gravity concentration zone because its grinding cost is much lower than the manganese in

Ore-dressing methods fall naturally into two general subdivisions— (1) concentration methods and (2) direct-recovery methods (amalgamation and leaching or wet methods). Concentration methods are employed to remove worthless gangue material and concentrate the valuable minerals of the crude ore in a smaller bulk.
