The mixture was heated at 95 ° C. for 4 to 6 hours to react. 350 g of manganese sulfate and 150 g of ferrous sulfate were obtained.

<실시례2>Example 2

물 600g에 황산 360g을 넣어 만든 황산용액에 MnO₂100g, 페로망간100g, 고철5g을 넣고 95℃로 4∼6시간동안 반응시켜 용액을 여과한 후 과망산가리 3g을 넣어 철성분을 산화시켜서 제거시킨 후 용액을 여과한 후 여액에 아연말 1g을 넣어서 중금속을 제거하고 여과한 용액을 건조시켜서 황산망간 350g을 얻었다.100 g of MnO _2, 100 g of ferro-manganese and 5 g of iron were added to a sulfuric acid solution made by adding 360 g of sulfuric acid to 600 g of water. The solution was filtered at 95 ° C. for 4 to 6 hours, and the solution was filtered. After filtering the solution, 1 g of zinc powder was added to the filtrate to remove heavy metals, and the filtered solution was dried to obtain 350 g of manganese sulfate.
