黄铁矿烧渣的综合利用研究

Research on Comprehensive Utilization of Slag of Pyrite

本文介绍用硫酸溶解黄铁矿烧渣中的金属氧化物 ,用铁刨花还原Cu ,真空浓缩析出Fe2 (SO4 ) 3以用来制备高效静水剂 (聚合硫酸铁 ) ,残渣中的金用氰化法回收 ,从而为黄铁矿烧渣的综合利用创造了一种新的前景。

This paper introduced that metal-oxides consisted in slag of pyrite burning is dissolved in H 2SO 4, CuO is deoxidized with ferrous paring, polymerizing iron sulphate is gotten in vacuum,which used as the reagent of purify liquid water, and gold is reclaimed with cyaniding in infusible slag in H 2SO 4,so as to open up new prospects for the compreheasive utilization of slag of pyrite.
