3. magnetic separation process

Manganese carbonate ore has weak magnetism, while the associated gangue minerals are mostly non-magnetic silicate minerals. Therefore, strong magnetic separation can be used to enrich manganese carbonate.

Magnetic separation has the advantages of small footprint, low energy consumption, low cost, economy and environmental protection. Different magnetic separation methods can be used for different types of manganese carbonate ores. For example, when processing high-iron manganese carbonate ore, wet weak magnetic separation can be used for rough separation, and then the coarse concentrate can be swept through strong magnetic separator, so that the target minerals iron and manganese can be recovered separately.

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. General magnetic separation equipment includes dry magnetic separators, wet magnetic separators and high gradient magnetic separators.
