硫铁矿烧渣制备氧化铁黄和氧化铁红

Preparation of Iron Oxide Yellow and Iron Oxide Red With Pyrite Cinder

对利用硫铁矿烧渣制备氧化铁黄和氧化铁红进行了研究。考察了影响硫铁矿烧渣还原、酸溶、中和、氧化等过程的各种因素。结果表明，在适宜的条件下，利用烧渣可以制备出用做颜料的氧化铁黄和氧化铁红。

In this paper,the preparation of iron oxide yellow and iron oxide red with pyrite cinder was studied.Some factors that affect the reduction of pyrite cinder,the acid solution,the neutralization and oxideization were investigated.Experimental results showed that iron oxide yellow and iron oxide red could be made with pyrite cinder under suitable condition.
