METHOD OF SEPARATION OF THE MINERALS Russian patent published in 2007 - IPC B07C5/342 

FIELD: mining industry; methods of dressing of the mineral resources.

SUBSTANCE: the invention pertaining to the field of the minerals dressing, in particular, to the methods of of the radiometric separation of the ores, and may be used for separation of the fluorescent minerals. In the process of separation of the minerals conduct transportation of the minerals in the form of the monolayer stream of the being separated material, its irradiation by the penetrating radiation, registration of the intensity of the luminescent emission of the mineral from the side opposite to the incident stream of the penetrating radiation, comparison of the intensity with the preset threshold value and the subsequent separation of the useful mineral according to the outcome of the comparison. Additionally conduct registration and storage of the intensity of the luminescence of the air and change the threshold value proportionally to received value of the luminescent emission of the air. Irradiation by the penetrating radiation conduct the incident stream with the width larger than the width of the stream of the separable material; the intensity of the air and the mineral luminescent emission is registered under the flat angle (180°) or the blunt angle concerning the incident stream of the penetrating radiation. At that the air luminescent intensity is registered beyond the limits of the width of the stream of the separable material, and the intensity of the luminescent emission of the mineral is registered within the limits of the width of the stream of the separable material in the zone of the material irradiation and-or behind it along the material motion. The invention ensures the increased selectivity and the self-acting maintenance of the level of the separation, that allows to exercise the process of the separation of the minerals more efficiently.

EFFECT: the invention ensures the increased selectivity and the self-acting maintenance of the level of the separation, that allows to exercise the process of the separation of the minerals more efficiently.
