摘要：
This invention relates to a process for centrifugal separation of materials contained in a liquid slurry. The slurry includes a light material having a specific gravity which is less than the specific gravity of the liquid carrier and a heavy material having a specific gravity which is greater than the specific gravity of the liquid carrier. A gas, preferably air, is injected into the slurry prior to feeding the slurry to a hydrocyclone.
