新疆托里金矿的矿石性质复杂,含有大量的硅酸盐(辉石、长石、绿泥石、钙斜长石)及黄铁矿毒砂等矿物。采用活性炭吸附碘量法不适于该矿石的分析,我们采用泡沫塑料富集金的方法进行了探索性试验。本方法使用泡沫塑料吸附,使金与其他金属离子分离,硫脲溶液解脱,原子吸收法测定。此方法在选择性,取料方法上都有独到之处。现已投入生产,经实践证明,此法简便快速,精密度高,准确度符合要求,方法分析范围为0.×—××克/吨。
The ore in the Tori Gold Mine in Xinjiang is complex in nature and contains a large amount of minerals such as silicates (pyroxene, feldspar, chlorite, calcium plagioclase) and pyrite. Adsorption of iodine with activated carbon method is not suitable for the analysis of the ore, we use the method of foam gold enrichment exploratory test. This method uses the foam plastic adsorption, the separation of gold and other metal ions, thiourea solution liberation, atomic absorption spectrometry. This method has its own advantages in terms of selectivity and picking methods. Has been put into production, proven by practice, this method is simple and fast, high precision, accuracy meet the requirements, the method analysis range of 0. × - ×× g / ton.
