有色冶金高铁高硅渣炼制生铁的应用探讨

Application analysis on slag of nonferrous metallurgy with higher ferric oxide and silica

有色金属火法冶炼过程普遍产生高铁高硅炉渣,其产量大、难处理的特点导致了金属资源的浪费,也造成了环境污染。结合有色冶金高铁炉渣化学成分,对其直接作为炼铁炉料做了资源性评价。分析了当前有色冶金渣提铁现状以及提铁产品质量,提出其在耐候钢、部分含铜不锈钢方面应用的新思路。

High ferric oxide-and silica-bearing slag is generally produced in the nonferrous metallurgical process.Its output is very large and it is difficult to handle,leading to waste of valuable metals and pollution of the environment.To recover the valuable elements and make recycling use of the slag,the chemical composition and properties of the slag,the possibility of using the slag as raw materials for ironmaking and steelmaking are evaluated.The current situation of extracting iron from nonferrous metallurgical slag and the iron product quality are analyzed,and some suggestions to its potential application in steelmaking are given.
