砷存在于许多硫化物处理过程的溶液中,我们有必要了解它在水系统中的形态以及各种物质的反应。本文详细论述了砷以不溶的无机化合物形式从水溶液中的沉淀,以便从各种湿法冶金工艺的流出液中除砷。验证了各种沉淀物的溶解度和稳定性。已经发现,目前所用的许多砷化物在废料场如尾矿池中比以前所公认的更易溶解,更不稳定。 Arsenic is present in many solutions for sulfide treatment, and we need to understand its morphology in water systems and the reactions of various substances. This paper details the precipitation of arsenic from an aqueous solution as an insoluble inorganic compound to remove arsenic from the effluent of various hydrometallurgical processes. The solubility and stability of various precipitates were verified. It has been found that many of the arsenic currently used are more soluble and less stable than previously recognized in scrap yards such as tailings ponds.
