Evaporation-Cooling Coupling Method to Remove the Calcium and Magnesium Impurities in Leaching Solution of Manganese Ore

Calcium and magnesium impurities are the major impurities in the leaching solution of manganese ore, which will influence the produce of manganese sulfate. Solubility determinations of calcium sulfate, magnesium sulfate and manganese sulfate in water have been carried out from 273.15K to 373.15K. Ac...

Description
Summary:Calcium and magnesium impurities are the major impurities in the leaching solution of manganese ore, which will influence the produce of manganese sulfate. Solubility determinations of calcium sulfate, magnesium sulfate and manganese sulfate in water have been carried out from 273.15K to 373.15K. According to the basic data, a new method to remove Ca2+ and Mg2+ impuritis in leaching solution has been put forward. The removal ratios of calcium and magnesium impurities could reach 48.5% and 39.2% using the new method, respectively.
