| Abstract: | 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 Beneficiation 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 beneficiation indexes of No.1 shop become as good as those of No.2 shop. |
| |
| Keywords: | beneficiation index difference reducing of ore size fed to grinding secondary grinding of ore re-processing of concentrate from gravity separation |
