长周期电积锌工艺研究

Study on Long Period Zinc Electro-deposit Process

针对高锗硫化锌精矿,重点开展了浸出过程杂质元素锗等入渣控制技术、硫酸锌溶液中杂质的深度净化工艺和长周期锌电积工艺的研究,电积锌析出的锌片厚度大于3 mm,为国内实现机械化剥锌技术奠定基础。

Aimed to zinc sulfide concentrate contains higher germanium, the technique that controlling impurity element including germanium into residue in leaching process, deep purification and long period electro-deposit process of zinc sulfate solution are studied. The results show that the thickness of deposition zinc is more than 3 mm, which would establish foundation for realizing mechanization of ripping zinc technique in China.
