矿物岩石中金的湿法分析若干问题的探讨

Discussion on a few points of wet assay of gold in mineralized rock

本文研究了矿物岩石中锑、铊、汞对湿法测金的干扰及其消除方法。考查了高砷、汞样品焙烧时金的挥发性。用新的缩分取样公式研究了提金工艺实验样品湿法分析金的准确性。

This paper made a research of the disturbance given by antimony, thallium and mercury to wet assay of gold in mineralized rocks and ways of their elimination.The volatility of gold when roasting high arsenic or mercury content of samples was investigated. Furthermore, the accuracy of wet assay of gold in experimental sample was studied by means of new reduction sampling formula.
