Abstract: The technology that high pur ty manganese carbonate is gained by precipitation from homogeneous solution,manganese minerals used as materials, is studied in this article . experiments show that conditions of reaction have considerable influence on the product quality and the precipitated rate of manganese. In the best condition ( the temperature is 115 ℃ , molratio between urea andmanganese sulfate is 1. 10 , the reaction time is 90 min ) , the precipitated rate of manganese achieves 98.3% and the product quality achieves GB10503- 89I type .

Key words: high purity manganese carbonate, precipitation from homogeneous solution, manganese sulfate
