A disclosed sand washing apparatus may be used for separating organic material from a mixture comprising sand and organic material. The apparatus may comprise: a wash chamber for accepting a mixture comprising sand and organic material, an agitator, a collection chamber, and a conveyor configured to transport sand away from the collection chamber. The disclosed method for recovering sand from a mixture comprising sand and organic material may comprise the steps of: introducing the mixture into a chamber, allowing organic material to ascend while allowing sand to descend, subjecting a portion of the descending sand to a turbulence that creates a lifting action, and recovering sand that has descended past the turbulence.
