众所周知,金矿样品的制样方法对金含量测试分析结果的精确度与准确度有直接的影响.作者对湖北茅坪含金石英脉矿样的制样方法及其制样过程中试样的混匀工序进行了对照试验.提出了含金石英脉类型矿样的简便可靠的盘磨制样法及对角提取搓散法的混匀工序.既解决了自然金难于粉碎的矛盾,又能克服对角提取混匀法因样品粉碎过细结球包裹细粒金致使难于混匀的现象.通过分析结果检查,证实选用盘磨制样法及对角提取搓散法对含金石英脉类型矿样的样制是行之有效的.
It is well-known that the sample preparation method of gold samples has a direct impact on the accuracy and accuracy of gold content analysis and testing results. The author of the sample preparation method and the sample preparation process Mixing process of the control test was made.A simple and reliable sample preparation method of grinding gold-bearing quartz vein type sample and the mixing process of diagonal extraction rubbing method were proposed.It not only solved the contradiction of natural gold which was hard to be crushed, but also To overcome the diagonal extraction mixing method because the sample crushed fine ball wrapped fine gold resulting in the phenomenon of difficult to mix.Through the analysis of the results confirmed that the choice of disk grinding sample preparation and diagonal extraction rubbing method for the gold-bearing quartz vein type ore Sample-like is effective.
