随着锰铁合金生产发展,对富锰矿需要日益增加。由于我国缺乏富锰矿,多年来,冶金工作者为扩大锰铁合金原料,合理利用国家资源,对利用锰铁比低的铁锰矿生产人造富锰渣的新工艺,进行了研究。并曾研究水煤气沸腾炉还原磁选分离和旋风炉熔炼分离等方法。与高炉二步法相比,同样分离 With the development of ferromanganese production, the need for manganese ore is increasing. Due to the lack of manganese rich ore in our country, for many years metallurgical workers have made researches on the new technology of producing man-made manganese-rich slag by using ferromanganese with low ferromanganese content in order to expand the raw material of ferromanganese alloy, make rational use of national resources. And has studied water boiling furnace reduction magnetic separation and cyclone furnace melting separation methods. Compared with the blast furnace two-step method, the same separation
