FIELD: physics.
SUBSTANCE: positive and negative search indicator features and characteristics are detected in search samples using an analytical method. The search indicator features used are the detection of mineral particles in the search sample with a scattered occurrence form of indicator elements, as well as particles with their own mineral form. The search indicator characteristics used are values which characterise the element and mineral phase granularity of the search samples. Integral-scintillation element-phase spectral analysis is used to search for and evaluate quality of the mineral raw material.
EFFECT: high efficiency of searching for mineral raw material owing to high reliability and rate of detecting mineral irregularities in search samples.
