用湿法处理低品位复杂锡精矿,是国际锡业科技工作者致力研究的新课题。在收集大量资料,比较不同工艺的反复实践中,找到一条最佳工艺。经碳热还原后的矿石,用新的电解法一次性处理,同时得到锡及副产品铁盐,工艺流程短,设备简单,成本低,锡的回收率>95%。 Wet processing of low-grade complex tin concentrate, is a new task of international tin industry science and technology workers. In the collection of large amounts of data, compare different processes of repeated practice, find the best technology. After the carbothermal reduction of ore, a one-time use of the new electrolytic treatment, while tin and by-products of iron salts, the process is short, simple equipment, low cost, tin recovery> 95%.
