我队根据化探普查找矿需要,结合当地实际情况,对以下三种化探分析方法进行了部分改进:1、矿石中硫化物的铜、钴、镍物相分析用饱和溴水和几滴浓溴浸取以硫化物形式存在的铜、钴、镍,比加拿大地质调查所介绍的方法(以抗坏血酸和过氧化氢混合溶剂浸取12小时)速度快,提取较完全.据1973年分析870个矿样的结果整理、计算、作图后,通过硫和硫化物中铜、钴、镍几何平均值的对比,发
According to the geophysical prospecting prospecting needs of our team, combined with the local actual situation, the following three kinds of geochemical analysis methods were partially improved: 1, the sulfide in the ore copper, cobalt, nickel phase analysis with saturated bromine water and a few drops Concentrated bromine leaching of copper, cobalt and nickel in the form of sulphides is faster and more complete than the method described in the Canadian Geological Survey (leaching with a mixture of ascorbic acid and hydrogen peroxide for 12 hours) .According to 1973 analysis 870 Results of a mineral sample collation, calculation, mapping, through the sulfur and sulfide in the geometric mean of copper, cobalt, nickel contrast, hair
