摘要
研究了以生产DSD酸的废渣铁泥为原料制备高纯氧化铁红的新工艺。考察了影响铁泥酸溶、煅烧等过程的各种因素。结果表明，在反应温度80℃，反应时间60min，液固质量比4：1，硫酸用量为理论量的1．1倍，氧化剂用量为铁泥的1％～2％（质量分数）时利用铁泥可以制取高纯度的氧化铁红，转化率可达到97％，质量符合HG／T2574-1994优等品标准。
The new craft of producing ferric oxide with high purity from waste iron mud was studied in this paper. The factors which influenced the acid - soluble process of iron mud and calcination were thoroughly investigated, the results show that when the reaction temperature is 80 % ,reaction time is 60 rain. ,liquid to solid is 4：1 ,the amount of H2SO4 is 1.1 times of theory amount and the oxidant to iron mud is 1% - 2% （ mass ）, the convention rate of iron mud can be 97% and the quality of the high purity ferric oxide can meet the superior grade of standard of HG/T 2574 - 1994.
