用锍试金法富集矿石中铂族元素,目前已引起广泛的重视。但是,经锍试金富集后的铂族元素如何测定尚存在许多问题。国内普遍采用锑试金富集,灰吹除去大部分锑,光谱法测定锑珠中的铂族元素,方法仍较繁琐,且大量锑的挥发对操作者身体也不利。本文试验了锍扣经酸处理、除去贱金属硫化物后,酸不溶性铂族元素硫化物富集渣(以下简称富集渣)在高温灼烧滤纸时的行为。发现在少
Sulfide assay gold ore enrichment in the platinum group elements, has attracted widespread attention. However, there are still many problems in the determination of platinum group elements after sulfonium test-enrichment. Antimony test gold enrichment generally used to remove most of gray ash blowing antimony, antimony beads in the determination of platinum group elements, the method is still cumbersome, and a large number of antimony volatile on the operator is also detrimental. This article tested the matte button acid treatment, remove the base metal sulfide, the acid insoluble platinum group element sulfide enrichment slag (hereinafter referred to as enriched slag) at high temperature burning filter paper behavior.
