为此该厂进行了技术扩容改造。通过引进新型BF型浮洗机，采用一粗二精浮选新工艺流程进行稀土选矿。
By introducing into the "BF" model floatation equipment, replacing the old technology with the new one, it completes the floatation by the once corse and twice well floatation technique.
这种金精粉经微爆处理后，由于组成矿物的特性发生了一系列的变化，加之脱除了残留在矿粒表面的浮选药剂，金的浸出率可得到大幅度的提高。
After microcrack treatment, their leaching rate can be notably increased with decrease of the content of freely soluble copper and removal of flotation reagent on mineral surfaces.
采用一段磨矿-部分混合浮选-混精铜铅分离、混选尾矿选锌流程及无氰药剂，提高了精矿品位及铜、铅、锌、银回收率。
Higher selective composite collectors and combined depressants without cyanide were used in part-bulk flotation and Cu-Pb separation of Pb-Zn ore containing silver and copper.
