The article substantiates the relevance and necessity of developing mathematical models in foundry production, as well problems prospects their use. Based on an analytical review world literature it was emphasized that many studies authors literary sources, not enough attention is paid to development technological process extracting non-ferrous metals from slag industrial waste. A brief descrip...

Alumina is a common substance deporting in copper smelting slags when various secondary fractions, e.g. e-scrap or WEEE, are used as feedstock such along with primary sulphide concentrates. Properties of iron-silicate at high alumina concentrations, the iron-alumina spinel saturation, have been studied 1300 °C by temperature equilibration-quenching method combined EPMA (electron probe microanal...

Abstract Most of the solid household waste generated in world is disposed by incineration. Wastes during incineration debris pose a danger to environment and must be of. Determining application areas incinerator slags an urgent research task. The article provides information on conditions volumes slag formation. It possible extract copper-containing material from gravitational enrichment. use c...

The Balkan Peninsula played a crucial role for the introduction of metallurgy during Copper Age and numerous archaeometallurgical examinations have delivered highly interesting insights on this topic. However, there is lack systematic analytical research copper ore smelting metal exchange later Bronze Age. In paper we focus first results slags from sites Ružana, Trnjane Čoka Njica, Eastern Serb...

Vanadium extraction methods were developed for iron-vanadium-phosphorus (FeV-P) melts derived from processing of V-bearing titanomagnetites and steel slags. Studies on phase relationships of V slags were carried out to provide important understanding of the extraction processes. Phase relationship in vanadiferous slag was investigated experimentally at 1573K, 1673K and 1773K, for the compositio...

As one solid waste with potential for phosphorus removal, application of slags in water treatment merits attention. But it was inhibited greatly by alkaline solution (pH>9.5) and cemented clogging generated. To give one solution, phosphorus removal was investigated by combining deep-sea bacterium Alteromonas 522-1 and basic oxygen furnace slag (BOFS). Results showed that by the combination, not...

The article describes the effect of fluxing ability (FA) ores used as a flux on slag formation and copper losses. In Kazakhstan, at Balkhash smelting plant (BCSP), currently fluxes have very low SiO2 content—about 62%—whereas Al2O3 content is 12%. Its was estimated, it shown that silica an exceedingly FA. Only half participate in formation. To obtain slags with magnetite concentration, consider...

The theoretical equation for predicting volume expansion of steel slag is deduced based on both chemical reaction and physical changes of free lime in steel slag during the hydration process. Laboratory volume expansion testing is conducted to compare the results with the theoretical volume expansion. It is proved that they correlated well. It is furthermore experimentally proved that certain v...

The knowledge of sulfide capacities FeO-containing slags is necessary for better understanding the resulfurization reaction in hot metal pre-treatments. In this study, copper-iron-sulfur liquid alloy was equilibrated with CaO–SiO2–FeO ternary slag to measure and FeO activities simultaneously at temperature below melting point pure iron. experimental result that capacity increased increasing con...
