利用含铜混合液生产碱式碳酸铜

Use Copper-bearing Mixture to Produce Basic Copper Carbonate

采用氧化和中和沉淀方法,以H_2O_2作氧化剂、Na_2CO_3作脱杂剂脱除含铜混合液中的As、Fe、Ni、Ca、Pb等杂质,利用其与碳酸钠反应生产减式碳酸铜,并使产品质量达到出口要求。

Hydrogen peroxide as oxidizer and sodium carbonate as remover, arsenic, iron, nickel, calcium and lead are removed from copper-bearing mixture by neutralization and precipitation, then use the liquor that have been filtrated react with the sodium carbonate to produce basic copper carbonae and make the quality of the product meet the export request.
