摘　　要：通过对齐大山选矿厂改为阶段磨矿、粗细分选、重选-强磁-阴离子反浮选工艺流程后,2005年下半年一选和二选车间生产指标差距增大原因进行分析,提出缩小两选指标差距的措施。From the second half of 2005 on, the beneficiation indexes of No. 1 and No. 2 shops （they adopt the same process： stagewise grinding-rough ＆ fine classification- gravity separation-high-intensity magnetic separation-anion inverse flotation） of Qidashan Benefieiation Plant differ from each other day by day. The reasons thereof are analyzed. Measure are taken in No. 1 shop with the goal that the benefieiation indexes of No. 1 shop become as good as those of No. 2 shop.
