The present paper introduces the steel production and BOF slag processing techniques in Steelmaking Sector of Bayuquan Iron and Steel Subsidiary, Ansteel. The technology of slag tailings utilization has been developed under the consideration of the properties of slag tailing and the characteristics of slag forming in BOF steelmaking operation practice. The processing of the BOF slag includes ho...

Copper ore processing generates a large amount of copper slag, which has properties that are similar to fine aggregate. slag promising future in the construction industry as an alternative Up 50% aggregate substitutions have been successful. The performance concrete could be improved by microbiologically induced calcium carbonate precipitation. impact micro-organisms on mechanical and flexural ...

The present paper investigated the process of the slag wool fabrication using high temperature blast furnace (BF) slag modified by coal ash (CA). The liquidus temperature and viscosity of the slag system with different mass ratios of BF slag and CA were measured through an inner cylinder rotation method. The approximate mass ratio used to fabricate the slag wool was therefore determined and sla...

The article deals with the problems of slags processing from copper-smelting production, both current production and those which had been accumulating over many years enterprises' activity in heaps (stale). There are data about possible methods slag processing. It is proposed a technology for joint stale Urals pyrite cinders (waste sulfuric acid) - smelting obtain poor matte, into copper precio...

The current research on metallurgical remains from scientific excavations in northeast Yunnan the Bronze Age period is insufficient. In order to study smelting technology of north-eastern Yunnan, samples slag and mineral excavated Yubei Di site Dongchuan were examined. Based outcome characterization analysis, a simulation was executed utilizing software Factsage 7.1 generate phase diagram that ...

Copper matte converting is an essential process in copper pyrometallurgy. Replacing traditional batch Peirce–Smith converters (PSCs), continuous becoming a new trend. In this work, thermodynamic modeling of the was carried out under actual production conditions. There were five phases process: matte, copper, Cu2O, slag, and gas. To directly produce anode divided into oxidation period reduction ...

Ground granulated blast furnace slag is widely used as a mineral admixture to replace partial Portland cement in the concrete industry. As the amount of slag increases, the late-age compressive strength of concrete mixtures increases. However, after an optimum point, any further increase in slag does not improve the late-age compressive strength. This optimum replacement ratio of slag is a cruc...
