摘要
砷矿床,从其地球化学特点看,绝大部分均以共、伴生形式复合于有色金属硫化物矿床中,单一的砷矿床较为少见。由于砷的毒性,在开采利用有色金属矿时,砷除少量回收外,绝大部分均以“三废”形式排放,形成环境污染。我国探明砷储量为世界砷总储量的70％,当前生产利用中普遍存在浪费资源、污染环境的问题,应引起环保部门重视,为保护资源,化害为利,提出了综合治理的建议。
Viewd from the geochemical aspexts, most of the arsenic deposits are compounded with non-ferrous metal sulfide ore deposits in the form of paragenesis or association, and simple arsenic deposit is rarely found. Due to the toxicity of arsenic, in the process of mining and utilizing non-ferrous metal ore deposits, most of the arsenic is discharged in the form of“three wastes, except a small amount of them recovered, which causes environmental pollution.. The proved arsenic reserve in our country occupays 70% of the tot al arsenic reserve in the world. The resource waste and environment al pollution are common in the production and utilization of arsenic resources, to which much attention should be given by the environment protection de-partments. In order to prevent the resource from watse and turn harmful material into useful thing, suggestions are propesed so as to make comprehensive control.
