化学取样的目的是确定矿石中有益有害组份的含量及其分布规律,并作为划分矿石工业类型,圈定矿体、计算储量和损失贫化的依据.取样结果正确与否直接影响矿床的工业评价.因此,化学取样是找矿勘探和矿山地质工作中一项重要的工作.几年来随着地质勘探事业的发展,金属矿床化学取样工作也有较大的改进和提高.如某些矿区结合矿床地质特点采用了一些较经济合理的取样方法、放宽取样间距,和加工K值确定等方面都取得了一定成绩.这些成绩对提高地质勘探工作效率、改善劳动条
The purpose of chemical sampling is to determine the content of harmful and harmful components in ore and its distribution law, and as a classification of ore industry, delineation of ore bodies, calculation of reserves and loss of depletion basis. Sampling results correct or not directly affect the industrial evaluation of the deposit Therefore, chemical sampling is an important work in prospecting and geological work of mines.In recent years, along with the development of geologic exploration, the chemical sampling of metal deposits has also been greatly improved and enhanced.For example, some mines combined with the deposit geology Characteristics Some reasonable and reasonable sampling methods have been adopted, some sampling intervals have been relaxed, and K values have been determined, etc. These achievements have made great achievements in improving the efficiency of geological exploration work and improving the working conditions
