岩矿鉴定在金定量分析中的应用

Rock-mine Identify in the Gold Application of the Quantitative Analysis

金在地壳中的平均含量为5×10-9,在矿石中以自然金、固溶体类金矿物、化合物类金矿物存在。在金定量分析前,进行岩矿鉴定。根据鉴定中金元素在矿体中的赋存状态和粒级,在制样、焙烧、溶样过程中,针对性地采用适合该状态金分析测试的制样方法、焙烧方法、溶样方法,可明显提高金定量分析效率和准确度,节省生产成本。

The average content of gold is 5×10 -9 in the earth’s crust .And the gold exists as the natural gold and gold mineral. Determining the rock and mineral before the gold quantitative analysis. According to the existing state and particulate of gold in the mineral, and using the methods of making sample 、roasting and disintegrating purposely which are fit for the gold analysis and test of this state ,it can improve efficiency and accuracy of gold quantitative analysis clearly and save the manufacturing cost.
