利用低品位铜矿生产氧化铜和高纯三氧化二铁

The Production of Copper Oxide and High Purity Ferric Oxide from Low-grade Copper Ores

研究了低品位铜矿生产氧化铜及铜盐并利用其副产物 Fe SO4 经除杂纯化后与辅助材料焙烧生产高纯氧化铁红的工艺路线 ,讨论了矿石的粒度、酸度、除杂、提纯、焙烧温度对产品质量的影响 ,优化出最佳工艺条件。

The technological process of producing copper oxide and copper salts from low grade copper ores was described in this paper.By product,ferrous sulfate,produced in the process can be used for production of high purity iron oxide red through removing impurities and roasting ferrous sulfate under condition of adding auxiliary material.The effect of ore size,acidity,removal of impurity,roasting temperature etc,on product quality was also discussed.The optimal condition for the process was proposed.
