In light that a gold ore contains much slime and many barren and associate bodies and gold dissemination particle size is fine,cyclone is used for flotation roughing concentration grading composing a flotation-cyclone grading joint flowsheet and achieves good outcome.Industrial production results show that it can quickly and efficiently recover most monomer gold and goldbearing pyrite from flotation roughing concentrates and improve gold recovery rate to use cyclone for grading of flotation roughing concentrates.The shortcone cyclone can achieve better gold recovery rate than grading hydraulic cyclone,which is 75.04 %.
