摘要
砷的毒性众所周知,然而,为了获得高质量的阴极铜,在阳极和电解液中必须含有一定量的砷。砷、锑、铋的含量取决于阳极板内各成份的相对含量。本文将讨论砷在铜电解过程中的行为和益处,以及锑、铋对阴极板和电解槽的不利影响。同时本文也讨论了将砷、锑、铋引起的阴极污染、浮泥、结圬和阳极钝化等不利影响最小化或加以缓解。
The toxicity of arsenic is well known and documented.However,the presence of arsenic in copper electrorefining anodes electrolyte is critically necessary to produce high quality cathode.Asenic as well as antimony and bismuth concentrations vary depending on their relative concentration in the anode copper received from the smelter.This paper will discuss the behavioue and benefits of arsenic in copper elecrorefining and the detrimental effects of antimony and bismuth on cathode quality and tankhouse performance.This will include the minimization and mitigation of problems associated with arsenic,antimony and bismuth including cathode contamination,floating slimes,scaling and anode passivation.
