ActiveMethods for chemical analysis of copper concentrates―Part 17：Determination of aluminium oxide content―Chromazurol S spectrophotometric method and fluoride salts device-Na2EDTA titrimetric method
铜精矿化学分析方法 第17部分：三氧化二铝量的测定 铬天青S胶束增溶光度法和沉淀分离-氟盐置换-Na2EDTA滴定法
Application Summary AI generated
This standard specifies two methods for determining aluminum oxide content in copper concentrates: the Chromazurol S spectrophotometric method for low concentrations and the fluoride salts device-Na2EDTA titrimetric method for higher concentrations. It is applied in the metallurgical industry for quality control and chemical analysis of copper concentrates during mining, smelting, and trading processes. The standard ensures accurate measurement of alumina, which is critical for evaluating concentrate purity and optimizing subsequent smelting operations.
