High-alumina cement production from FeNi-ERF slag, limestone and diasporic bauxite
AbstractIn this paper the utilization of ferronickel electroreduction furnace (FeNi-ERF) slag for the production of high-alumina cement (HAC) is investigated through laboratory and pilot-scale tests. The process followed consisted of smelting reduction of slag mixtures with low-grade diasporic bauxite and limestone. In the laboratory-scale trials the main process parameters were defined, concerning raw material proportions, kinetics of the reductions and cooling rate of the product. The presence of a carbon-containing iron bath enhances FeOx reduction from the slag. Products from laboratory tests developed satisfactory compressive strengths relative to those of commercial HAC. According to the results of the laboratory tests, pilot-scale heat treatments were carried out in a 5-t electric arc furnace (EAF) and about 4 t of final mixture were produced.
