Abstract: The application of high efficient energy saving and discharge reducing technology is introduced from the more crushing less grinding technique, stage grinding technique, single magnetic separation, coarse and fine separation. The equipment application of high efficient energy saving and discharge reducing are described from the large-scale ball mill, new type wearable materials, Slon high intensity magnetic separator, MVS high frequency vibrating screen. And the industrial tests of RA-315, RA-515,MZ-21, RA-715, LKY anion reverse floatation collectors and small type tests of LKD anion reverse floatation are discussed. Besides, the situation of water saving, air pollution controlling, mine biology system resuming, comprehensive utilization of tailings are introduced. 

Key words: More crushing less grinding, Coarse and fine separation, Anion reverse flotation, Energy saving and discharge reducing
