快速质量法测定合质金品位

Determination of gold in gold bullion by quick mass method

黄金矿山氰化浸出、活性炭吸附、解吸电解工艺生产的合质金锭，杂质成分简单。采取样品配银熔融，合粒经硝酸分金，质量法测定金含量。方法速度快，准确度适应中国人民银行收购合质金的质量要求。

Through the proeess flow of cyanide leaching,activted carborn absorption,and desorption electrolysis ,the gold bullion is obtaind in which the composition of impurity is simple.Adding silver to the sample to be melted,the combined granules are decomposed by nitric acid,then determining it by mass method.This method is rapid for determination,accurate,according with quality demands of purchasing gold bullion by the people’s bank of China
