Description
Изобретение относитс к сортиров-; ке и области предварительного обогащени руд и других полезных ископаемых и может быть использовано в рудоподготовительных переделах различных типов минерального сырь .The invention relates to sorting; Ke and areas of preliminary enrichment of ores and other minerals and can be used in the ore preparation of various types of mineral raw materials.
Известен способ рентгенорадиомет-, рического обогащени полезных ископаемых , заключающийс в последовательном пропускании кусков перед датчиком первичного гамма-излучени , возбуждении в куске вторичного гамма-излучени , регистрации вторичного гамма-излучени от каждого куска и разделении кусков относительно заданного порогового значени критери обогащени 1.A known method of X-ray radiometric enrichment of minerals consists in sequentially passing the pieces in front of the primary gamma radiation sensor, inducing a piece of secondary gamma radiation in the piece, registering the secondary gamma radiation from each piece and separating the pieces relative to the specified threshold value of the enrichment criterion 1.
К недостаткам известного способа ОТНОСЯТСЯ применение в качестве критери обогащени отношени характеристических флуоресцентных рентгеновских излучений двух элементов, ограниченность применени способа и изменчивость форм и размеров кусков руды, вызывающа варьирование воздушного зазора между датчиком и облучаемой поверхностью.The disadvantages of the known method are the use of the ratio of the characteristic fluorescent X-rays of two elements as an enrichment criterion, the limited application of the method and the variability of the shapes and sizes of pieces of ore causing a variation in the air gap between the sensor and the irradiated surface.
Целью -изобретени вл етс повышение эффективности обогащени полезHfcix ископаемых.The purpose of the invention is to increase the efficiency of minerals HFcix enrichment.
Указанна цель достигаетс тем, что согласно способу рентгенорадиометрического обогащени полезных ископаемых , заключаквдемус в последовательном пропускании кусков перед источниками первичного гамма-излучени , возбуждени в куске вторичного гамма-излучени , регистрации вторичного гамма-излучени от .каждого This goal is achieved by the fact that, according to the method of X-ray radiometric enrichment of minerals, concludes with the demus in sequential transmission of the pieces in front of the sources of primary gamma radiation, excitation in a piece of secondary gamma radiation, registration of secondary gamma radiation from each
10 куска и разделении кусков о.тносительно заданного порогового значени критери обогащени , производ т одновременное измерение характеристического флуоресцентного рентгеновско15 го излучени и рассе нного от куска гамма-излучени пропорциональными счетчиками, а в качестве критери обогащени используют отношение интенсивности характеристического The 10 pieces and pieces of pieces with respect to a given threshold value of the enrichment criterion, simultaneously measure the characteristic fluorescent X-ray radiation and the gamma radiation scattered from the piece by proportional counters, and the enrichment ratio is the characteristic
20 флуоресцентного рентгеновского излучени элементов к интенсивности рассе нного куском гамма-излучени источника , при этом интенсивность рассе нного излучени регистрируют в 20 fluorescent x-ray radiation of elements to the intensity of a source scattered by a piece of gamma radiation, while the intensity of scattered radiation is recorded in
25 энергетической области, соответствующей фотопику рассе нного излучени , а так же тем, что обогащение золотосодержащих руд по генетическому спутнику золота ведут, регистриру 25 of the energy region corresponding to the photopic of scattered radiation, as well as the fact that the enrichment of gold-containing ores through the genetic satellite of gold is carried out, registering
