River sand dredged from Missouri River at Kansas City varies from trace to 0.25% lignite; maximum concentration of .008% lignite is allowed without adverse effects on finished surface; new patented deligniter consists of 30 in. by 24 ft, 150 tph horizontal screw washer; deligniting plant discharges through hydraulic valves to 30 in. by 100 ft self-propelled radial stacker; all sand is first sent to rerun pile until it is assayed for lignite; if batch assays less than .008% lignite, it is switched over to finished stockpile.
