INFLUENCE OF DIELECTRIC-BARRIER DISCHARGE ON THE VALENCE STATE OF IRON AND NICKEL IN AQUEOUS SOLUTIONS (Papers SGEM2018)

R. Yakushin, V. Kolesnikov, V. Brodskiy, A. Perfilieva, A. Chistolinov
Thursday 11 October 2018 by Libadmin2018
ABSTRACT Dielectric barrier discharge is low-temperature plasma generated in cases with an dielectric material between the electrodes. The demanding applied task of water treatment is the removal of heavy metal ions, including iron (Fe) and nickel (Ni), ions, from aqueous solutions. The (...)


INVESTIGATION OF THE INFLUENCE A MORPHOLOGIC CHARACTERISTICS OF THE NOBLE METAL PARTICLES ON GRAVITY EFFICIENCY DEVICES (Papers SGEM2018)

S. Korchevenkov, T. Aleksandrova
Thursday 11 October 2018 by Libadmin2018
ABSTRACT The article covers the theory of gravity separation suspension flows. The indicated factors affect the separation processes. The proposed criterion estimates the possibilities of dividing the hydraulic separation coefficient, which is alternative the equal fall coefficient, but taking (...)


LEACHING OF URANIUM FROM COAL BY ALKALINE AND MIXTURE OF SODIUM CARBONATE AND SODIUM BI-CARBONATE (Papers SGEM2018)

E. M. Makhatha, L. S. Patience
Thursday 11 October 2018 by Libadmin2018
ABSTRACT In this study, alkaline leaching using sodium carbonate and sodium bicarbonate analysis was applied on different raw samples while the raw samples were digested to analyse the uranium content prior to leaching using successively ICP-OES. The recovery of Uranium is by use of very (...)


PRELIMINARY ANALYSIS OF ELEMENTS IN WATER SUPPLY SLUDGE AT RoNNEHOLMS MOSSE FIELDS, SOUTHERN SWEDEN (Papers SGEM2018)

M. Hogland, J. Burlakovs, G. Celma, Z. Vincevica-Gaile, W. Hogland
Thursday 11 October 2018 by Libadmin2018
ABSTRACT Sydvatten AB operates the water plant Ringsjö Agency in Stehag, Southern Sweden, and the company has since the 1970s deposited waterworks sludge in the sludge landfill at Rönneholms Mosse (bog), Sjöholmen (WGS84 55°48’46.1"N 13°18’25.6"E). In order to handle the produced future waterworks (...)


PROCESSING OF CARBONACEOUS ORES CONTAINING ULTRA-DISPERSED METALS WITH USING HIGH-FREQUENCY CURRENT (Papers SGEM2018)

A. Afanasova, T. Aleksandrova, N. Nikolaeva
Thursday 11 October 2018 by Libadmin2018
ABSTRACT Due to the depletion of free-milling raw materials the involvement of new types of deposits is the strategy of developing mining industry of Russia. The black shale raw materials show interest as a non-traditional source of precious metals since its genetic and positional gold-carbon (...)


RESEARCH OF THE PURIFICATION PROCESSES OF CHLORIDE MAGNESIUM MELTS FROM IMPURITY COMPONENTS (Papers SGEM2018)

A. Yessengaziyev, A. Ultarakova, B. Kenzhaliyev, M. Onayev, K. Kasymdzhanov
Thursday 11 October 2018 by Libadmin2018
ABSTRACT The production of a titanium sponge obtained by the reduction of titanium tetrachloride by magnesium is accompanied by the formation of a huge amount of chloride waste. They are annually stored in landfills - storages, polluting the environment. Consequently, one of the topical (...)


RESEARCH OF THE RHEOLOGICAL PROPERTIES OF PULPS IN THE SEPARATION OF MINERAL RAW MATERIALS (Papers SGEM2018)

A.O. Romashev, V. A. Potemkin, T. N. Aleksandrova
Thursday 11 October 2018 by Libadmin2018
ABSTRACT Separation processes are highly influenced by medium in which separation is performed, particularly its rheological properties. One of the most important rheological parameter of medium is viscosity. Many researchers have noted the primary role of viscosity in separation processes. (...)


RESEARCH ON DOLOMITIC LIMESTONE CAPITALIZATION IN TERMS OF ECONOMIC EFFICIENCY (Papers SGEM2018)

A. Donea Ciocan, C. Badulescu, D. Marchis, T. Goldan, M. C. Nistor
Thursday 11 October 2018 by Libadmin2018
ABSTRACT This paper presents the research undertaken in order to establish a processing technology for the Budureasa dolomitic limestone. For this, a series of physico-chemical and mineralogical analyzes were performed, but also unitary processing operations such as grinding, calcination, (...)


RESEARCHMENT OF CARBONACEOUS ORES DRESSABILITY WITH THE USE OF DIRECTIONAL EXPOSURE (Papers SGEM2018)

U.M. Pavlova, A. O. Romashev, T. N. Aleksandrova
Thursday 11 October 2018 by Libadmin2018
ABSTRACT Among the carbonaceous ores, the shales occupy a special position in terms of formation, petrographic and chemical composition, and in their characteristic role in the development of the fuel and chemical industries. One of the promising types of this raw material are dictyonema (...)


RUTILE AND QUARZ INCLUSIONS IN ECLOGITIC GARNETS FROM THE BULKUR ANTICLINE OF THE NORTNEASTERN SIBERIAN PLATFORM (Papers SGEM2018)

A. Biller, S. Ugapeva, V. Popov
Thursday 11 October 2018 by Libadmin2018
ABSTRACT Inclusions in diamond associated minerals are additional information about the formation of minerals in the depths of the mantle. Considerable attention is paid to the study of rutile inclusions in garnets in literature. Until now, there is no consensus on formation of oriented (...)
