摘要
溴加氯化钠溶解含金矿样中的金是迄今为止人们所知道的金的最佳溶剂。该溶剂对金的溶解速度272mg／cm3·d。利用聚胺酯泡沫塑料（以下简称泡塑）富集含金矿液中的金，在该体系中如何选择泡塑吸附的最佳条件，是本文的关键。含金泡塑采用无臭灰化技术，以达到方便测试的目的。通过大量样品、标样测试，与经典方法对比，与省局测试中心外检结果对比，证明本方法准确可靠，简便快速，成本低廉。
It is well known thet the bromic sodium chloride is the best solvent in dissolving the gold from the gold ore, its dissolved speed is 272mg/cm3 pera day. It is common to use polyurethane to adsorpt gold from gold-bearing solustion, how to choose the best adsorption condition of the polyurethane plastic is the crux of the matter discussed in this paper. In order to simplify analysising processes, the gold-bearing plastic was processed with ouderless ashing technic. A large test data and the facts of comparing it with the classic methods and the retest result made by the xian institute of Mineral and Rock Experiment show that the method is characterized by accuracy, reliability, convenient and the low cost.
