Brief introduction of producing method : pyrolusite powder direct acidification method (two-mine method)
1, Chemical combination method : It can save investment and reduce pollution and cost because this method cut the calcination process.
2, Main materials : pyrolusite and pyrite react with vitriol, and then remove the impurities to get manganese sulfate solution, which react with ammonium bicarbonate to produce Manganese carbonate.
