METHOD OF VIZIOMETRIC ANALYSIS OF QUALITY OF ORE AND DEVICE FOR IMPLEMENTATION Russian patent published in 2017 - IPC B03B13/00 B07C5/34 

FIELD: chemistry.

SUBSTANCE: method viziometric analysis of ore quality involves the preparation of ore sample, the formation of the flat portion of the sample, and illumination in the zone of fixing of images formed by the measurement the flat portion of the sample in the visible spectrum, a computer image analysis calculation of mass fraction, ratio of the basic mineral forms and impregnation of minerals. To improve the accuracy of the analysis of the mineral composition of the ore, flat portion ore is formed at the lower end of the sample formed by placing a sample on a transparent plane surface, the lighting and fixing the flat image portion of the sample are carried from the bottom up in the two-dimensional scanning operation, comprising, for example, longitudinal movement along the planar portion sample frontally oriented to the flat portion of the sample measurement area. Preparation of ore sample comprises crushing ore to a particle size -5 mm, Allocation class 1 -3 mm, Washing and drying of the selected class. The method is carried out by using apparatus comprising a table for placing the sample, a source of light flux, a device for transmitting a light signal, the optical transmitter of light signal into digital, the controller. The apparatus is equipped with a device for the joint movement of the luminous flux source and means for transmitting signal light source or a light flux device to transmit the light signal and optical signal light transmitter along the table for placing the sample. The source of the luminous flux is formed as a light pipe. Device for transmitting light signal is in the form of longitudinal mirrors and longitudinal lens. The optical transducer is a longitudinal photosensitive element. Source of light flux, the device for transmitting a light signal and an optical transmitter are arranged below the table for placing the sample, with the ability of front moving along a table for placing the sample.

EFFECT: improved accuracy of analysis of the mineral composition of the ore.
