The aim of the paper was to evaluate the geometrical properties of regular and irregular chalcedonite particles contained in enrichment products obtained in a laboratory ring jig. Investigative programme included carrying out the tests of aggregate enrichment together with the vision analysis of regular and irregular particles of feed and enrichment products obtained from different layers of the jig bed. Various types of shape coefficients were calculated and the most effective among them for the assessment the particle shape, were selected. The particle size distribution of the feed and their enrichment products according to the minimum Feret’s diameter, were also determined. The results obtained by the vision system were discussed in the context of its potential utilization in evaluation of the enrichment process of mineral aggregates in a water jig.
