试验以菱锰矿为原料制备球团，并对其工艺条件和产品质量进行了研究和检测。结果表明。在一定的条件下制得的菱锰矿球团可作为中、小型高炉和电炉冶炼的原料。 Rhodochrosite was used as raw material to prepare pellets, and its process conditions and product quality were studied and tested. The results show. Rhodonite pellets obtained under certain conditions can be used as raw materials for the smelting of medium and small sized blast furnaces and electric furnaces.
