摘要
为减少排入环境中的含砷危险固废量,寻求治理砷污染的高效方法。通过综述冶金和化工行业焙烧、烧结及熔炼等过程产生的主要以氧化物形态存在的含砷烟尘,以及净化除杂过程中产生的硫化砷渣、砷酸盐渣的提取利用研究现状,比较分析各提取方法的优势与缺陷,展望含砷物料中砷的提取与利用研究趋势,获得高效提取砷的最新工艺方法。
In order to explore an effective process for reducing the quantity of arsenic discharged into environment,several kinds of technologies involving hydrometallurgical and pyrometallurgy for utilizing the arsenic dust produced during roasting and smelting in metallurgical and chemistry industry,as well as the arsenic sulfide and arsenide in purification process were reviewed detail. The advantages and flaws existing in these methods were also compared and analyzed thoroughly. In the end,the trend of treating arsenic waste goods effectively were prospected.
