毒砂是分布较广的硫砷化合物,常与钢、铅、锌、硫、钨等硫化矿物共生。在选别过程中常进入精矿,导致硫化矿精矿含砷过高,它不仅使冶炼复杂、成本高,而且严重污染环境。长期以来,人们对脱砷的研究主要集中在捕收剂和无机抑制剂方面,很少涉及有机抑制剂。 然而,有机抑制剂具有适应多种需要的特性,如稳定性、还原性、配位能力、亲水性、溶解能力,加上成本低、环保、安全方面的优越性,日益引起人们的重视。本文选 Arsenopyrite is a widely distributed sulfur and arsenic compounds, often with steel, lead, zinc, sulfur, tungsten and other sulfide minerals symbiosis. In the sorting process often into the concentrate, resulting in sulfide ore concentrate containing arsenic is too high, it not only the smelting complex, high cost, but also seriously pollute the environment. For a long time, people’s research on arsenic removal has been mainly focused on collectors and inorganic inhibitors, with little involvement of organic inhibitors. However, organic inhibitors have attracted more and more attentions due to their many properties such as stability, reducing ability, coordination ability, hydrophilicity, dissolving ability, low cost, environmental protection and safety.
