基于几年来的许多现场经验,作者意见在设计浮选厂粗选回路时,采用长列浮选机比以每列的处理量相应少的多数短列浮选机,可获得较高的处理能力和回收率,并得到较好的生产效率。最近在阿特拉斯联合采矿开发公司12,000吨/日铜选厂的现场进行试验研究,这个意见进一步从实践中予以证实。 Based on a number of field experience over the years, the authors suggest that the use of long columns of flotation machines for the selection of roughing circuits in flotation plants provides higher throughput than most short column flotation machines with a correspondingly lower throughput per column And recovery, and get better production efficiency. A recent pilot study at the 12,000 ton / day copper processing plant at Atlas United Mining Corporation was further substantiated in practice.
