Abstract
Gold flakes and small nuggets are separated from heavy sand by fluidizing the mixture with an upwardly flowing water column having a very uniform velocity across its section. The upwardly flowing water column has sufficient flow to fluidize the suspended material but not enough to carry the heavy sand over the top of the column. Heavy sand is withdrawn from the upper portion of the fluidized mixture to leave the gold below the withdrawal point.
