Abstract Scope |
The reduction of Ghana’s Opon Mansi iron ore (OPM) using chars generated from end-of-life acrylonitrile butadiene (ABS) has been investigated in a horizontal tube furnace. Composite pellets of the pulverised ore (-250 μm) containing pulverised chars of ABS (-250 μm) were rapidly heated at 1200 and 1500 °C under high purity argon gas and the off gas was continuously analysed for CO and CO2 using an online infrared gas analyser (IR). The extent of reduction after 40 min was calculated at each temperature and the metal produced was characterised by XRD and SEM/EDS analyses. The results show that OPM consists of medium grade hematite (assaying 74.56 wt % Fe2O3), which is easily reduced within 40 min by ABS. It was concluded that metals production from iron ores is a promising route for disposing of No. 7 plastics, which are usually not recycled in Ghana. |
