Paper Abstract

The paper presents the research results of pegmatites from Karelian deposits. The aim of this research was to find selective features of microcline, biotite, muscovite, quartz, and plagioclase for determining the opportunity of their selection from original ore by optical sorting method which based on color differences of analyzed objects. Studies have shown that the solution of the problem of these minerals separation is possible in 3 stages. In the first stage groups "microcline", "muscovite and biotite", "quartz and plagioclase," are separated according to the values of channels hue H and lightness L in the color model HLS. In the second stage biotite and muscovite are separated from each other by the values of the channel hue H and saturation S. Finally, in the third stage couple "quartz - plagioclase" are separated. But these minerals are indistinguishable from each other by color, so it's proposed to separate them by selective feature "surface structure."
