摘要
针对西藏某铜矿磨矿系统与浮选系统处理能力不匹配、浮选时间不足、选矿回收率较低的问题,对该选矿厂浮选工艺流程进行了改造和生产实践。通过利用闲置浮选机设计一套独立快速浮选系统,达到了有用金属“能收早收”的目的,有效延长了精选系统的浮选时间,同时缓解了粗扫选作业的浮选压力。工艺改造后选矿指标有了大幅度提升,铜回收率由71.69%提高至75.65%,金回收率由38.37%提高至43.01%,银回收率由38.91%提高至55.72%,钼回收率由20.78%提高至22.38%,年增加经济效益可达人民币8140万元,生产实践效果与经济效益显著。
Aiming at the problems of mismatch between grinding system and flotation system,insufficient flotation time and low recovery of a copper ore in Tibet,the author has reformed the flotation process and put it into practice in this paper.By designing an independent and fast flotation system using idle flotation machine,the purpose of useful metals harvesting early has been achieved,the flotation time of the flotation system is prolonged effectively,the flotation pressure of the roughing operation and cleaning operation is alleviated at the same time,and index has been greatly improved after technological transformation.The recovery of copper,gold,silver and molybdenum are increased from 71.69%to 75.65%,from 38.37%to 43.01%,from 38.91%to 55.72%,from 20.78%to 22.38%,respectively.The annual economic benefit can reach RMB 81.40 million yuan,the production practice and economic benefit are remarkable.
