The slag produced is very angular and porous with a rough surface texture (Figure 1). The chemical properties of the aggregates vary depending on the furnace, feed stock and slag formers used to produce the steel. The aggregate formed from the slag is comprised of calcium oxide (CaO), silicon oxide (SiO 2), iron oxide (Fe 2 O 3
Jan 27, 2020· Slag is a byproduct of metal smelting, and hundreds of tons of it are produced every year all over the world in the process of refining metals and making other industrial byproducts, slag actually has many uses, and rarely goes to waste. It appears in concrete, aggregate road materials, as ballast, and is sometimes used as a component of phosphate fertilizer.

The iron from these operations contains about % vanadium which is removed as slag by low temperature treatment with oxygen. In China this is carried out by spray refining, while in South Africa it is done in a shaking ladle and in Russia a special oxygen steel converter is used.
The model predicts the sulfur and silicon content in the metal and the FeO and sulfur content in the slag as a function of time. It is based on fourcomponent simultaneous mass transfer: sulfur and silicon in the metal and FeO and sulfur in the slag.

Abstract. Equilibrium between MnOCaOMgOSiO2Al2O3 slags and carbon saturated MnSiFeC alloys was investigated under CO at 1500 o C. Manganese and silicon activities were obtained by using the present data and the previously determined MnO and SiO 2 activities of the slag. Quadratic multicoefficient regression equations were developed for activity coefficients of manganese and silicon.
Jul 31, 2007· The first two controllers were installed on furnaces at Silicon Smelters near Polokwane in South Africa, one of which is up until recently been regarded as the largest silicon metal furnace in the world. Subsequent to these installations, a further Minstral was installed on a large FeSi furnace at the PEM furnace at Laudun in France in October ...

We are industry specialists in solid / liquid separation and mineral processing applications for the minerals, chemical and industrial markets offering ...
Work has been conducted to investigate the effects of FeO in the slag and silicon in the metal on hot metal desulfurization. Laboratory experimental results show that FeO decreases and silicon increases the rate of desulfurization. Silicon in the metal is consumed by the reduction of FeO and also by the desulfurization reaction. A mathematical kinetic model was developed to describe both the ...

Atoll Metal Recovery is a world leader in the provision of metal recovery services to metallurgical processors and mining companies. Since its formation, Atoll Metal Recovery has built 11 major metalfromslag recovery plants in Southern Africa, capable of processing between 120 and 200 t/h of slag.
The latter slag type is presented in Figure 5 and Figure 6. Fluxing to produce the required slag composition was carried out using either silica or a combination of silica and lime (in the form of burnt lime or limestone). The resulting ternary slag contained in mass percent about 3040% MgO, 3040% Al2O3 and 2030% SiO2. In the quaternary slag ...
