我厂用电硅热法生产的金属锰,多年来一直是以火法生产的富锰渣为基本原料,产品质量及经济效益不够理想,加上能生产优质富锰渣的锰矿石(Mn≥34%)越来越少,难以维持金属锰的现有生产水平。因此,设法扩大生产金属锰的原料来源及改善原料性质,已成为发展金属锰生产的一个关键问题。我们认为,采用湿法人造富锰矿作生产 The metallurgical manganese produced by our plant using electric silicon thermal method has been based on the manganese-rich slag produced by the fire method for many years. The product quality and economic benefits are not ideal, and the manganese ore that can produce high-quality manganese-rich slag (Mn ≧ 34%) less and less, it is difficult to maintain the current level of production of manganese metal. Therefore, trying to expand the sources of raw materials for producing metallic manganese and improving the properties of raw materials has become a key issue for the development of metallic manganese production. We believe that the use of wet man-made manganese ore for production
