摘要
分析了锡在钨湿法冶炼过程中的存在形态,提出了采用共沉淀工艺除去钨酸钠溶液中的杂质元素锡,考察了H2O2、试剂A的加入量及加入时期等对钨酸钠溶液中除锡效果的影响。
The behavior of tin in tungsten hydrometallurgy is analyzed, and a co-precipitation method is presented for removal of impurity element tin from Na2WO4 solution. The effect of H2O2 and reagent A addition is studied.
