在自然界中,砷的化合物相当多。其中有工业价值的只有很少几种砷的硫化物,多数情况是作为杂质存在于多种矿床中。无论是考虑产品质量或综合利用,还是避免环境污染,都要求选矿、冶金产品控制一定范围的含砷量。因此,在选矿、冶金的研究过程中,往往要求对矿石、焙砂、浸渣、烟尘、冷凝物等各类产品进行砷的状态考查。而砷的化学物相分析是进行砷的状态考查的主要手段之一。
In nature, arsenic compounds quite a lot. Among them there are only a few arsenic sulphides of industrial value, most often present as impurities in a variety of deposits. Regardless of product quality or comprehensive utilization, or to avoid environmental pollution, require dressing, metallurgical products to control a range of arsenic content. Therefore, in the process of mineral processing and metallurgy, it is often required to examine the status of arsenic in various products such as ore, calcine, residue, soot and condensate. The chemical phase analysis of arsenic is one of the main means to examine the state of arsenic.
