Obogashchenie Rud

A number oftechnological developments are presented in this issue, based on application of dry methods of ore-preparation and beneficiation, significantly decreasingenvironmental damage, caused bymining and processing operations.


So, the paper by V. I. Lyashenko, et al., describes the scientific and practical results in development of radiometric technologies and technicalfacilities for preconcentration of uranium ores with a view to accomplish sorting of ore mined underground and carry out reprocessing of dumped wastes by means of modular installations. The authors propose, that separated cut-off grade ore and barren rock may not be wound up to surface, but instead used for backfilling ofcavities, filling of mine roads and rail tracks or such reject materials may be subjected to leaching.


Possibilities of low-grade scheelite ores separation by means of X-ray absorption method on TOMRA Sorting equipment are considered in the paper by I. V. Alushkin, et al. As a result of the studies, it was established that preliminary separation permits to increase WO3 content in subsequent flotation processing stage feed by the factor of 4-5, removing at the process head up to 84 % of machine-processed size fractions as separation final tailings regarding WO3 grade, thus providing for capital and operating expenses decrease, without sacrificing of high metallurgical and economical results.


The methods of dry magnetic and electrostatic separation were successfully employed with a view to develop a technology for production of a marketable ilmenite product from the Butkinsky Mining and Processing Complex rougher ilmenite-zircon concentrate(the paper by S. V. Dmitriev,et al.). It is noted, that by means of application of dry processing methods, not only ecological performance is improved, but higher processing results are also obtained owing to the absence ofliquid resistance in material flow.


The last paper in this issue is also dedicated to the environmental-related topics. The paper presents the commercial-scale testing results of the wastewaters complex acoustical treatment installation, developed by the author (S. A. Bakharev), being tested for treatment of effluent water discharged by mining-and-processing operations, located in valleys of spawning streams. It is shown, that with industrial wastewaters discharge of 500-3500 m3/hr, efficiency of acoustical purification from suspended substances and heavy metals reaches 85-90 %, and, with subsequent daily settling – 95-97 %.
