Obogashchenie rud (Mineral processing)

“Obogashchenie Rud” is the leading journal in the field of mineral processing, concentration processes and technological mineralogy. Published since 1956. Volume up to 48 pages, 6 issues per year, circulation up to 1,000 copies. ISSN 0202-3776.

Mission of the journal is to elucidate innovative directions of development of mineral processing science and practice in Russia and abroad.

Publications cover different kinds of mineral and raw material resources: iron and non-ferrous ores, non-metallic mineral resources, technogenous materials. All spectrum of the processes and technologies applying for processing of these materials and ores is elucidated: crushing, comminution, classification, separation with usage of gravitational, electrostatic, magnetic, radiometric and other methods as well as flotation, pyro- and hydrometallurgy, sintering, filtration, thickening etc. The journal also publishes papers about development of the new equipment for mineral processing and crushing. Special sections are devoted to putting into practice and usage of up-to-date analytical methods for ores and products during mineral processing, provlems and remedies of technological mineralogy. The field of development of automatic control systems in mineral processing, designing and engineering of mining and concentrating works (from large industrial complexes to mobile modular units) are observed. Especial attention is paid to environment protection measures, storage and utilization of wastes, ground reclamation. Applied investigations are added by prospective developments in the field of fundamental science. "Obogashchenie Rud" journal is an expert peer-review edition. It gives also information about national and international events for mineral processing specialists, where "Obogashchenie Rud" is an information partner or sponsor, as well as about scientific bodies and industrial enterprises operating in the field of mineral processing and personally about famous scientists and specialists.
