A method of sizing finely ground, insoluble, homogeneous material or
classifying ore particles. A weighed quantity is dispersed in liquid and
allowed to settle for a timed period, a liquid fraction then being
decanted. The treatment is repeated several times, the settled fraction
now representing one size group (if homogeneous) or settled group (if
minerals of various densities are present). The decanted fluid is
similarly treated for progressively lengthened settling periods.
