| Abstract Scope |
The Ghana Integrated Iron and Steel Development Corporation (GIISDEC) was established in 2019 to exploit commercial iron ore deposits in the Country. This initiative necessitates the search for locally available materials that can substitute for conventional materials used for iron and steelmaking technologies. This work investigated the response of Ghana’s Akokorowa iron ore to reduction by chars of end-of-life tyres (ELT). Composite pellets of the ore-ELT mixture were subjected to gas emission studies by heating in a horizontal tube furnace under pure argon flowing at 1.0 litre/min followed by analyses of the offgas using a continuous infrared (IR) gas analyser. Reaction products were characterised by SEM/EDS and XRD analyses and the extent of reduction was determined. The results indicated that premium grade iron nuggets can be produced from the Akokorowa iron ore using ELT as reductant and measured extent of reduction was up to 100% after 40 min of heating. |
