Ore and Metals: Obogashchenie rud (Mineral processing)

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.

Author`s data	Kameneva Ye. Ye. , elena.kameneva@mail.ru
Abstract	The results of technologicalmineralogical studies of gabbrodiabases and granites — main types of rocks, used in Karelia for crushed stone production, are presented. It is shown, that crushed stone, produced in gabbrodiabases crushing, is characterized by stability of properties. Main characteristics of granite crushed stone are less consistent, indicating a necessity of more detailed study of granites at the stage of geological prospecting and exploration works.

Abstract	The article describes the advantages of KID^® crushers as compared with other machines in production of cubeshaped crushed stone. It is shown, that the main distinction of inertia crushers from widely known eccentric crushers consists in adjustable reduction ratio of crushed material, permitting one KID^® crusher to take the place of two crushing stages. Introduction of simplified twostage processing flow sheets at crushed stone production plants permits to reduce capital investments in their construction by 32 %, power inputs — by 20 %, reduce liners steel wear almost by the factor of two, and increase labor productivity more than by 20 %.
Keywords	Cube-shaped crushed stone, crushing, KID^® crusher, two-stage crushing flow sheet.

Abstract	The results of the study of thickening process as a preoperation prior to hydrometallurgical treatment stage in the Arkhangelskoye and Nikolayevskoye deposits gold-bearing ores processing are reflected in the article. It is shown, that regarding the Arkhangelskoye deposit ore with high content of friable minerals that form large quantity of fine size fractions in grinding, flocculants application in thickening is required. In thickening feed ore of the Nikolayevskoye deposit as well as tailings, produced in this ore processing, application of flocculants is not advisable.

Abstract	Promising outlook in application of particle dynamics and discrete element methods for modeling and optimization of a wide variety of natural and man-made materials treatment processes is shown. These approaches permit to take into consideration important factors that are disregarded by other approaches, providing for detail visualization of processes, also in «stroboscopic illumination», which permits to discern slow components. Advance in this trend may serve as impetus to development of new effective machines and technologies. Primary tasks are set for investigations. General statement of respective tasks is presented.
