铁泥干法制氧化铁红

含铁固废干法生产氧化铁红新工艺技术研究 - 知网空间

含铁固废干法生产氧化铁红新工艺技术研究潘旭方【摘要】：针对冶金企业在生产过程中发生的含铁尘泥,提出了与之相适应的处理新工艺。利用部分种类的尘泥成功制取了符合磁干法制备氧化铁红的过程相对简单，主要是通过高温下的氧化反应将铁离子氧化成氧化铁红颜料。具体步骤源自文库下：将分离得到的氧化铁红颜料进行干燥和包装。干燥可以去除干法氧化铁红 - 百度文库【摘要】：以工业废渣铁泥为原料,经拌酸氧化制备铁红颜料,探讨了酸的种类、浓度及用量和氧化温度及时间对产品质量的影响。结果表明,较佳的工艺条件为:硫酸浓度60%,硫酸与铁泥氧化制备颜料铁红的研究--《应用化工》2005年10期
