摘要
本文分析了脉金矿化验品位偏差较大的原因,提出取样代表性、制样方法同化验技术一样,对造成偏差具有同等重要的作用。提出了新的取样量计算式和避免偏析的制样方法。
After analysing the factors resulting in greater analysis error in lode gold grade, the paper points out that like chemical analysis technique, the sample representiveness and the sample--preparating method have an important effect on the grade analysis of lode gold ores. The author gives an equation for calculating sample quantity and some sample--preparating methods to avoid chemical analysis errors.
