摘要

摘要:锰是发展新兴工业所必需的原料,随着锰块矿资源的日益紧缺,高效利用锰矿粉及精矿资源对于降低铁合金生产成本、扩大原料来源具有重要意义。为了改善锰矿电炉冶炼效率,对入炉锰矿粉及精矿进行造块是必不可少的步骤之一。综述了锰矿粉3种主要造块方法及其研究进展,基于天然锰矿粉成分复杂且金属相与脉石矿物结合紧密的特点,对烧结法、球团法及压团法的原料要求、工艺特点、固结机制及产品性能进行了归纳和比较,认为人造富锰块矿入电炉冶炼可以大幅提高电炉冶炼效率。结合当前低碳减排的大背景,对今后锰矿粉造块工艺发展趋势进行了展望。

Abstract

Abstract: Manganese is a necessary raw material for the development of emerging industries. With the increasing shortage of manganese lump ores, the effective utilization of manganese ore fines and concentrate is of great significance for not only reducing the production cost of ferroalloy but also expanding the source of raw materials. In order to improve the smelting efficiency of electric furnace, it is one of the necessary steps to agglomerate the manganese ore fines and concentrates. Based on the complex composition of natural manganese ore fines with close integration of metal phase and vein minerals, three main agglomeration methods of manganese ore fines and its research progress were reviewed. The requirements of ingredient, technological features, consolidation mechanism and product performance of sintering, pelletizing and briquetting methods were summarized and compared, and it is believed that the smelting efficiency of electric furnaces can be greatly improved by feeding manganese artificial lump ore into electric furnaces. Combined with the background of low carbon emission reduction, the development trend of manganese ore fines agglomeration process in the future is prospected.
