A SUSTAINABLE TAILINGS REPROCESSING PROJECT: A CASE OF STUDY IN PORTUGAL (Papers SGEM2018)

J. Figueiredo, M. C.Vila, A. Fiuza
Thursday 11 October 2018 by Libadmin2018
ABSTRACT Tailings embankments are part of the legacy left by the intensive mining industry. These vast impoundment storages are associated with some adverse environmental and social impacts creating insecurity to the stakeholders. Mining tailings may also be a source of minerals with high (...)


ASSESSMENT OF THE POSSIBILITY OF USING WATERS FROM POLISH HARD COAL MINES AS A SOURCES OF RARE EARTH ELEMENTS (Papers SGEM2018)

B. Bialecka, H. Swinder, M. Thomas
Thursday 11 October 2018 by Libadmin2018
ABSTRACT In recent years we have observed a rapid increase in the demand for rare earth elements (REEs), related to industry intensive development in the field of new technologies. The biggest producer of REEs is China, which provides global markets with more than 83% of the whole amount of (...)


CHARACTERISTICS OF THE PROCESSING PRODUCTS FROM POLISH COPPER ORES IN TERMS OF THE QUALITY OF CONCENTRATES AND WASTES COMPOSITION, BASED ON MINERALOGICAL ANALYZES (Papers SGEM2018)

R. Kubik, A. Bakalarz, M. Duchnowska
Thursday 11 October 2018 by Libadmin2018
ABSTRACT Mineral processing products must be verified in order to develop highly effective technology of enrichment. At every stage of mineral processing - improvement is possible through monitoring and verification of the components of processes. Process control is possible, among others, (...)


COMPARATIVE RESEARCH OF CYANIDE AND SULFATE-CHLORIDE GOLD LEACHING FROM OXIDIZED GOLD-COPPER ORE (Papers SGEM2018)

A.Sekisov, A. Rasskazova, P. Korpi, T. Konareva, M. Rasskazov
Thursday 11 October 2018 by Libadmin2018
ABSTRACT The porphyry copper Malmyzh deposit is situated in the Russian Federation (Khabarovskiy kray). An oxidized ore sample from Malmyzh deposit with 0.8 ppm gold content was obtained and research of gold leaching of gold from oxidized gold-copper ore was carried out. Starved cyanide (...)


COMPARATIVE STUDY OF THE EFFECTIVENESS OF METHODS FOR EXTRACTING GOLD FROM STALE TAILINGS OF SORPTION (Papers SGEM2018)

А. Koizhanova, M. Erdenova, G. Sedelnikova, E. Kamalov, Z. Zhanabai
Thursday 11 October 2018 by Libadmin2018
ABSTRACT The results of refractory sorption tailings biooxidation and gold extraction from are presented. Selected of a representative sample and the phase composition of sorption tailings of the gold extraction plant LLP «Altyntau Kokshetau» was studied. According to the research it was found (...)


COPPER AND ORGANIC CARBON UPGRADING SELECTIVITY ANALYSIS IN THE COPPER ORE FLOTATION PLANT (Papers SGEM2018)

M. Duchnowska, A. Bakalarz
Thursday 11 October 2018 by Libadmin2018
ABSTRACT Polish sedimentary copper ore located in Lower Silesia (SW Poland) consists of three lithological fractions: sandstone, dolomitic and shale. The main copper-bearing minerals are chalcocite, bornite and chalcopyrite. The main carrier of organic carbon is shale ore. This part of ore is (...)


EVALUATION OF THE EFFECTIVENESS OF PRECIPITATION METHODS FOR THE SEPARATION OF RARE EARTH ELEMENTS (REES) FROM MINE WATERS (Papers SGEM2018)

B. Bialecka, H. Swinder, M. Thomas
Thursday 11 October 2018 by Libadmin2018
ABSTRACT The article presents the results of investigations into the effectiveness of precipitating rare earth elements (REEs) from mine waters using solutions of alkalinizing reagents (NaOH, Ca(OH)2, Na2CO3), sulphur-containing compounds (sodium trithiocarbonate, sodium (...)


EXTRACTION OF GOLD FROM MAN-MADE MINERAL RAW MATERIALS BY METHODS OF FLOTATION ENRICHMENT AND CYANING (Papers SGEM2018)

M. Erdenova, B. Kenzhaliyev, А. Koizhanova, S. Temirova, N. Abdyldaev
Thursday 11 October 2018 by Libadmin2018
ABSTRACT The effectiveness of the application of ultrathin grinding during processing of man-made raw materials (stale tails) of the Kazakhstan concentrator is shown. According to the results of rational analysis, gold is found in rock-forming minerals in finely dispersed form (28.2%), is (...)


FLORENCITE IN FLY ASH FROM THE RYBNIK POWER PLANT (POLAND) (Papers SGEM2018)

M. CEMPA, Z. ADAMCZYK, B. BIALECKA
Thursday 11 October 2018 by Libadmin2018
ABSTRACT The demand for rare earth elements (REEs) in the global economy has incentivised many researchers to search for alternative sources of those metals. For many years fly ashes have been the subject of such research, which indicate that they might be fit for REE recovery. One of the (...)


HYDROTHERMAL ACTIVATION OF FLY ASH FROM BROWN COAL COMBUSTION (Papers SGEM2018)

Z. ADAMCZYK, B. BIALECKA, M. CEMPA, G. MAJKA, A. POLANSKA
Thursday 11 October 2018 by Libadmin2018
ABSTRACT In Poland, like in many other countries, research is conducted toward creating sorbent materials based on fly ashes. The present shows the synthesis of fly ash from brown coal combustion in pulverised-fuel boilers of the Bełchatów Power Plant. The synthesis was conducted in an autoclave (...)
