现代的分析方法,可以称取1克或更少的样品定量地测定金.这就要求使用各种机械加工的手段,最大限度地使分析样品均匀.在天然的含金原料中,特别是在被分析的样品中,由于形成粒级为0.0n毫米或较大的包裹粒,样品含金的均匀性很差.对硫化矿、石英硫化物,石英三个矿种的六个样品,每个样品重15公斤原料中的伴生金,进行破碎研究.在金的浸染硫化矿中,有大小为0.000n—0.00n毫米,含金4.5g/T(1号样品);石英硫化矿,其伴生金粒的大小为0.006—0.06毫米,含金0.05;1.8;5.9g/T(2、3、4号样品).金的含量
Modern analytical methods, which weigh 1 g or less of sample quantitatively, require the use of a variety of machining techniques to maximize the uniformity of the analytical sample, and in natural gold-bearing materials, especially in In the samples analyzed, the uniformity of gold content in the samples was very poor due to the formation of inclusions with a grain size of 0.0 n mm or larger.For each of the six samples of the three minerals, sulphide sulfide, quartz sulphide and quartz, The samples were weighed with 15 kg of associated gold in the raw material for the crushing study. In the gold-impregnated sulphide ore, there are sizes of 0.000n-0.00n mm and a gold content of 4.5 g / T (sample No. 1); quartz sulphide ore, Gold size 0.006-0.06 mm, gold 0.05; 1.8; 5.9 g / T (Samples 2, 3, and 4.)
