"Contact plane concentration depends upon the principle that a thin sheet or film of water flowing over a plane surface may be so adjusted that its quantity and velocity are just sufficient to bear away the lighter particles of gangue, leaving behind only the heavier particles of the mineral to be concentrated, adhering by friction to the plane, the concentrates being removed by any convenient method. Thus we see it is best adapted to the concentration of minerals having widely differing specific gravities but may be used for the concentration of all ores and minerals with any specific gravity whatsoever" – p. 1.
