【摘要】 针对生产现场锌回收率低的问题,进行了相关试验研究,试验确定通过扫选添加硫酸铜、延长硫酸铜搅拌时间和改变硫酸铜添加顺序,能够有效提高锌品位和回收率,与设计药剂制度相比(搅拌时间由设计的2.5 min变为10min),锌品位提高2.87%,锌回收率提高1.84%。更多还原

【Abstract】 Based on the problem of low recovery of zinc of operating plant,the relative researches were conducted,and the test conditions of adding copper sulfate at scavenging,increasing the agitating time of copper sulfate and changing the dosing sequence of sulfate have a great influence on improving the grade and recovery of zinc. Contrast with the designed reagent system, the agitating time was changed from 2.5 min to 10 min,and the grade and recovery of zinc were improved by 2.87% and 1.84% respectively.更多还原
