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...

For beneficiation of converter slag, the role of surface phenomena on slag composition was studied. This work includes some experimental data, which were measured for basic oxygen steel (BOS) slag in Isfahan Steel Plant. All data were collected on site in the plant. The results support the idea that surface activity plays a major role in converter slag formation. It was also a new finding t...

The use of steel-making slag as catalysts for microwave-assisted dry reforming of CH4 was studied. Carbon materials (an activated carbon and a metallurgical coke), mixtures of carbon materials + Fe-rich slag and mixtures of carbon materials + Ni/Al2O3 were tested as catalysts. Mixtures of slag with carbons gave rise to higher and steadier conversions than those achieved over carbon materials. T...

The present investigation revealed the effect of using silica fume and copper slag as a partial replacement of cement and fine aggregate, respectively on the mechanical properties of the concrete. Due to the depletion of natural sand resource worldwide with the increment of industrial waste, simultaneously, partial replacements of fine aggregate with copper slag have been attempted. Therefore, ...

The effect of pig iron slag particles on soil physico-chemical, biological and certain soil enzyme properties was studied. Contamination of iron slag particles altered physico-chemical, biological and enzyme properties of soil. While soil pH increased slightly, electrical conductivity, carbon, potassium and phosphorus contents increased significantly in polluted soil. Contamination of soil with...

smelting of hammerable iron and its treatment in antiquity and Medieval produced also by-product: slag. Because of small yields of iron the process produced only small amounts of slag that did not attract attention of smelters concerning its possible use. the use of slag pieces was only accidental. a lot of slag pieces and blocks from slag pit shaft furnaces were used as a material for mound bu...

Alumina-rich iron ore is a widely existed polymetallic deposit in the nature, and it has a high comprehensive utilization value. Because the alumina and iron contents of alumina-rich iron ore vary from each other, there are many different measures and processes to recover iron and alumina from the various kinds of alumina-rich iron ore. In the blast furnace (BF) ironmaking process, the alumina ...

–The objective of present work is to use this industrial waste i.e. Slag as particulate filler material to the epoxy matrix composites by molding technique with different weight fractions ( 0%, 5%,10%,15%, 20% ) to study the mechanical behaviour of reinforced polymer composite material. The change in weight is studied for Slag under different tests like, tensile, bending and impact for obtainin...

(Received: November 27, 2010; Accepted: February 9, 2011) Abstract: The effect of pig iron slag particles on soil physico-chemical, biological and certain soil enzyme properties was studied. Contamination of iron slag particles altered physico-chemical, biological and enzyme properties of soil. While soil pH increased slightly, electrical conductivity, carbon, potassium and phosphorus contents ...

The surface tensions of a number of common commercial ferroalloys have been measured during their granulation in water. These measured values are significantly lower than would be expected from a normal metal-gas interface and are more typical of the interfacial tensions of slag-gas interfaces. This would seem to indicate that the slag-metal interface on the surface of a granule produces no sig...
