Manganese (Mn) is the twelfth most abundant element in the Earth's crust. Amongst some 300 minerals containing manganese, only about a dozen are of economic significance. Manganese is a silvery-gray metal that resembles iron. It is hard and very brittle, difficult to fuse, but easy to oxidize. Manganese metal and its common ions are paramagnetic.

When processing high-sulfur carbonate ores, the main gangue minerals are dolomite, pyrite, etc., and the use of strong magnetic separation technology will obtain better mineral processing indicators. When processing low-grade manganese carbonate ore, a high-gradient magnetic separator can be used to perform a coarse and sweep beneficiation process.

The Basics of Manganese Mining and Processing While exposure to manganese fumes, dust and compounds should be avoided, in safe formulas manganese is used by most everyone. The fact that manganese is such an important metal in our lives makes it clear that that mining of it is equally important.
Numerous processing modes have been utilised to attempt to beneficiate ferromanganese ores including one or more of: desliming, gravity separation, dry magnetic separation, high intensity ...
The gravity separation solution is only suitable for processing manganese ores with coarse embedded particles with simple structures, especially for dense oxidized ores. When using gravity separation solutions to treat oxidized manganese ore, crush the rock ore to around 6-10mm and separate the minerals.
