Role of Surface Phenomena on Converter Slag Composition

Abstract

<em>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 that Mg and S are strongly surface active in melt of converter slag. These findings contribute to better understanding of the slag composition. The ultimate aim of this work is to develop a novel practice, “molten flotation" for separating valuable constituents of converter slag.</em>
