ABSTRACT A method is disclosed for classifying sand wherein a mixture of sand and water is introduced into a classification tank partially filled with water. Depending on the weight of the sand grains, the grains of sand will precipitate at the bottom of the tank at graduated distances from an inlet pipe, the heavier particles nearest the inlet and the lighter particles farther away. To prevent large quantities of fines, i.e., sand grains between about 0.002 mm and 0.006 mm in size, from being lost by being washed out of the tank together with the overflow water, the water from tile tank is recirculated by means of a pump so that the water becomes progressively more saturated with fines, which means that larger amounts of fines will precipitate in the tank. Because the water is recirculated, water consumption can be reduced by 2/3, and at the same time the problem of the overflow water from the tank is also reduced.
