| Abstract: |
| Enlightened based on the separation characteristics in the air-sparged hydrocyclone(ASH)that both classification and flotation exist simultaneously,a modified fied air-sparged hydrocyclone(MASH)was developed to control the overgrinding of valuable materials with higher density in the fine grinding circuit for the first time.Investigations were made on the optimization of the geometric and operation parameters of the MASH,and on the effects of the physicochemical parameters of feed slurry on the MASH separation performance.A new classification system,which could be effectively used to control the overgrinding of valuable materials with higher density in the fine grinding circuit,was developed including MASH and conventional hydrocyclones. |
