ABSTRACT
The industrial utilization of Karelia’s technogenic deposits, such as mine dumps where the pegmatite veins of some deposits have been mined since the early 20th century, was studied. Sheet muscovite-mica was extracted from pegmatite. The use of environmentally safe processing technologies and an integrated approach to the extraction of all minerals are of great importance nowadays. Mine survey has shown that the veins of the pegmatite deposits in the Chupa-Louhi District, Karelia, are of different types responsible for the geochemical characteristics and quantitative ratios of minerals. This would have a negative effect when enriching by conventional methods using a common scheme. Nowadays, the most acceptable method for the utilization of technogenic dumps is a bulk technology for the mining and enrichment of rocks with the selective extraction of the major minerals of quartz, microcline, plagioclase, muscovite and other associated minerals. The development of sensor separation technologies, a unique, rational and profitable alternative to conventional dressing processes, has provided the opportunity to improve ore dressing processes and subsequent enrichment The dump utilization technology, which is now in progress, is expected to lead to low expenses and the high productivity of crushing and sizing operations and to offer general-purpose enrichment schemes for the complete extraction of minerals of different particle-size composition within one dump using the flow method. The economic efficiency of the utilization of artificial dumps can be considerably increased by making the extraction of major mineral concentrates (quartz, feldspars and muscovite) more complete.
