超级铁精矿制备氧化铁颜料

    Preparation of Iron Oxide Pigment by Super Iron Concentrate

    • 摘要: 近年来,国内铁精粉存在价格波动大、经济效益低等问题。本文通过以超级铁精矿为原料制备高品质氧化铁颜料可增加铁精粉附加值。考查了制备过程中各条件对颜料纯度的影响。实验表明,以抚顺某选矿厂超级铁精矿(TFe:71.81%)为原料,制得铁含量为98.20%的氧化铁黑,超出HG/T 2250—1991中一级品的铁含量3.20%;制得铁含量为97.60%的氧化铁红,超出GB/T 1863—2008中A类铁含量2.40%;制得铁含量为83.20%的氧化铁黄,超出GB/T 1863—2008中A类铁含量0.20%,三种颜料其余指标也均超出各自所规定的较优标准,为提高企业经济效益寻找另一种途径提供基础研究。

       

      Abstract: In recent years, there are some problems in domestic iron powder price fluctuation and low economic benefits. By using super iron concentrate as raw materials to prepare high quality iron oxide pigment, the added value of iron essence powder can be increased.The effect of various conditions in the preparation process on the pigment purity was investigated, and the results showed that iron oxide black with iron content of 98.20% was obtained using super iron concentrate(TFe:71.81%) from a concentrator in Fushun, which was 3.20% higher than that of HG/ T 2250—1991 medium grade. The iron oxide red with iron content of 97.60% was obtained, which was 2.40% higher than that of class A iron in GB/T 1863—2008. The iron oxide yellow with an iron content of 83.20% was obtained, which was 0.20% higher than the iron content of class A in GB/ T 1863—2008. The other indexes of the three pigments also exceeded their respective optimal standards, which provides basic research for finding another way to improve the economic benefits of enterprises.
