摘要
Abstract
Removal of germanium from neutral leaching solution during zinc hydrometallurgy was researched .The effect of iron concentration ,pH of leaching end point ,leaching time and temperature , production flow and production continuity on the germanium concentration in neutral leaching solution were examined .The results show that under the conditions of iron mass concentration of 1 .57 g/L ,pH of leaching end point of 5 .0-5 .2 ,leaching temperature of 78-82 ℃ ,leaching time of 3-5 hours and flow of 140-160 m3/h ,germanium concentration can be controlled less than 0 .6 mg/L ,the leaching solution can meet .zinc electrowinning requirements .关键词
