摘要
基于共沉淀原理,以氧化铋为沉砷剂,氢氧化钠为碱浸剂,氢氧化钙为苛化剂,进行电解液净化工序硫酸铜结晶后液脱砷试验研究,实现了砷的脱除,以及氧化铋、氢氧化钠的再生回用。
Based on the coprecipitation principle, the arsenic removal test after copper sulfate crystalliza- tion solution in electrolyte cleaning section was studied with bismuth oxide as arsenic removal agent, sodi- um hydroxide as alkali leaching agent, and calcium hydroxide as caustic agent, then the removal of arsenic, the reclamation and reuse of bismuth oxide and sodium hydroxide were realized in the test.
