High purity Manganese carbonate MnCO3

Manganese carbonate as the country vigorously promote new energy, reduce carbon emission reduction, promote low-carbon travel, battery industry by leaps and bounds, the demand for high purity manganese carbonate is also growing.  

The following is a brief introduction to the preparation process of high purity manganese carbonate:  

Raw material selection: high purity manganese metal as manganese source.  More than 99% sulfuric acid.  

Firstly, dilute sulfuric acid with pure water and add a certain amount of manganese metal to prepare manganese sulfate aqueous solution, filter and remove impurities.  

Take the standing manganese sulfate aqueous solution, add ammonium bicarbonate synthesis, according to the operation experience control synthesis end point.  

Washing, centrifugation, drying, packaging, storage.
