红土矿高炉冶炼含镍铁水的技术经济分析

Technical and economic analysis of Ni-containing hot metal production with laterite in blast furnaces

近年来,红土矿为我国不锈钢产业的快速增长提供了大量的含镍原料。目前红土矿冶炼主要以火法工艺为主,其中含铁较高的红土矿多采用高炉冶炼工艺。以一种含铁50.4%的红土矿为原料,采用高炉工艺冶炼含镍铁水,在关键工艺分析基础上,进行了技术经济分析,为红土矿在我国的合理利用提供参考。

In recent years, many Ni-containing materials manufactured from laterite have played a significant role in supporting the rapid development of the stainless steel industry in China. Currently, pyrometallurgy is the main process for laterite smelting, where blast furnaces are employed to make Ni-containing hot metal. With the aim of giving some references for making good use of laterite, technical and economic analysis was conducted in this paper, based on the discussion of the key technologies of Ni-containing hot metal production with laterite （50.4% Fe） in blast furnaces.
