FIELD: geological, ecological and agricultural investigations. SUBSTANCE: in correspondence with method of search for mineral wealth and ecological fouling search sample is taken, representative weight is separated from it and is mixed with liquid, representative weight of sample mixed with liquid is divided into fractions with the aid of mobile working surface carrying obstacles arranged on its edges. Fractions according to procedure are examined to find search indicating characters in them, direction of search for ore body or ecological fouling is evaluated by them. Search sample is divided in agreement with method into four fractions. Coarse fraction is separated by means of sieve, heavy fraction-concentrate, medium fraction-tailings and light fraction-sludge are derived with use of inclined mobile working surface carrying obstacles and performing reciprocating motions, light fraction is removed from it through holes in obstacles arranged on its edges. Medium fraction is collected in accumulator of tailings from which upper layer of liquid with lightest, fine particles of sample is drained into sludge accumulator. Direction of search for ore body or ecological fouling is evaluated by search indicating characters obtained as result of examination of fractions. EFFECT: enhanced quality and speed of search for mineral wealth and ecological fouling. 18 cl
