Claims (4)

1. Способ сепарации алмазов, включающий транспортировку породы в виде потока отдельных частиц, облучение породы рентгеновским излучением с широким энергетическим спектром, регистрацию распределения интенсивности излучения, прошедшего через участок потока породы, на разных энергиях, определение наличия в отдельных частицах породы алмаза и отделение таких частиц, отличающийся тем, что наличие алмаза определяют по характерным отклонениям двумерного распределения оптической плотности частицы породы от индивидуальной модели оптической плотности однокомпонентного вещества.1. A method for the separation of diamonds, including transporting the rock in the form of a stream of individual particles, irradiating the rock with X-rays with a wide energy spectrum, recording the distribution of the intensity of radiation transmitted through the section of the rock flow at different energies, determining the presence of diamond in individual particles of the rock and separating such particles , characterized in that the presence of diamond is determined by the characteristic deviations of the two-dimensional distribution of the optical density of the rock particles from the individual optical model the density of a single component substance. 2. Способ по п. 1, отличающийся тем, что индивидуальную модель оптической плотности строят для главного вещества методом робастной регрессии как полиноминальную модель двухмерной плотности.2.
