摘要
本文提出一种以废治废无污染的处理煤系硫铁矿的工艺。该工艺利用硫酸生产过程中所产生的废渣中的氧化铁,经处理后在硫酸介质中与硫铁矿反应,使硫铁矿中的硫和铁及烧渣中的铁资源得到充分的回收利用,既有利于环境保护,又具有良好的经济效益。
This paper has brought forward a new uncontaminnative technology of dealing with coal - derived pyrite, in which pyrite was reacted with ferric oxide in waste residue from vitriol production. By this mean , sulfur and iron resource in pyrite and iron resource in waste residue from vitriol production has been recovered and utilized plenarily. This is in favor of environment protection,and has favorable economy benefit.
