FIELD: mining.
SUBSTANCE: offered invention relates to a method for detection of a mineral in target material, a sorting method of raw material flow and to a device for determination of presence of target mineral in the material. The mineral detection method in the raw product involves irradiation of material rock fragments with electromagnetic radiation, for example microwave radiation, and recording of thermal response of material of rock fragments during or immediately after the irradiation to detect mineral in the material as per rate of its heating or its part on the recorded radiation.
EFFECT: proposed method is based on the fact that temperature change rate at heating of crystals by microwave radiation in target material is different, which allows improving efficiency and accuracy of sorting of rock fragments to detect presence or absence of mineral in a material respectively at power consumption reduction.
