How To Process Natural Manganese Sand?
Once the manganese sand is extracted, it is transported to a processing facility for crushing and screening. This step aims to break down the larger chunks of manganese sand into smaller, more uniform particles. The size of the particles may vary depending on the specific requirements of the water treatment application.

By screening manganese ore fines on 30 mesh screen and by utilising + 30 mesh fines only, 20 to 40 % of fines of — 30 mesh size get rejected. Hence in another trial only unscreened manganese ore fines were used and lime was added to the extent of 0.5 to 1 %. Lime acted as binder for fines and balls were formed in balling drum.
