An integrated approach to the use of optical characteristics of minerals for the development of an analyzer and a photometric separator is presented. It has been established that identification of pieces of veined and interspersed structures during photometric separation is not enough to use as a sign of separation the reflection coefficient of a piece. It has been revealed that it is necessary to scan the surface of a piece with a narrowly focused beam of light and use a special algorithm for processing optical information. To investigate the algorithms for identifying asbestos-containing pieces in photometric separation, a laser photometric analyzer has been developed that allows one to fix the reflection coefficients of a part of the surface of a piece when scanning it with a narrowly focused laser beam. It is noted that with its help it is possible to calculate the relative areas of reflecting minerals that occupy the surface of the sample under study. It is shown that in order to make a decision to remove a piece during separation it is necessary to know the content of the components in the piece. In this connection, it is of particular interest to consider the relationship between the ratio of the area and the weight content of the components in the pieces. As a result of the study, two formulas for calculating the content through known areas for vein and interspersed structures were obtained. It is established that the parameters of the size of the inclusions of minerals can be calculated if the coefficients of reflection of the constituent minerals are known. In this regard, it becomes possible to evaluate the content of a valuable component directly in the piece. To calculate the content, the form of inclusions is described using mathematical models of pieces of vein structure, which is characteristic of asbestos and interspersed structure - for coal and other minerals. The most effective algorithm for the identification of asbestos-containing pieces is established - the algorithm of the shared type. The results of imitating the sorting of asbestos ore are given |
