liquid liquid separation an overview sciencedirect topicsliquidliquid separation may be divided into two broad categories of operation. the first is defined as gravity separation, where the two immiscible liquid phases separate within the vessel by the differences in density of the liquids.gravity separation an overview sciencedirect topicsthe separability of minerals by gravity separation relies on a particles settling rate in a fluid. the terminal velocity of solid spheres settling in a fluid is described by stokes law for fine particles (eq. (.3)) or newtons law for coarse particles (eq. (.4)). both these equations include particle density as well as particle size.
