ABSTRACT. The consumption of iron ore has increased rapidly over the past decade due to the tremendous growth of the iron and steel industry. The depletion of high-grade iron ore resources makes it inevitable to utilise the existing low-grade iron ores/fines/tailings with proper beneficiation to meet the present specification and demand.
