Reuse of iron ore mineral wastes in civil engineering. Approximately 18,000 ha of land is currently under mining operations in Goa (Kumar, 2000).The present mining rate of 1621 million ton of ore, with high oreover burden ratio of around 1:3, means that there is a need of removal and disposal of 4050 million m 3 of waste per year.

201911&ensp·&enspFig. 1 shows the particlesize distribution of the iron ore jigging tailings sample and the concentration feed sample (grinding/classification at 1.4 mm). As observed, the d 80 of the tailings sample is approximately 4000 μm (4 mm) with only 4% of the particles below 37 μm (0.037 mm). The d 80 of the concentration feed sample is 840 μm (0.840 mm), with only 4% of particles below 10 μm (0

Chemical and Physical Variables Affecting Iron Ore
A statisticallydesigned experimental program has been used to study compositional and processing variables which influence the development of strength and reducibility of iron ore pellets. The effects of chemical composition and processing variables were investigated by indurating laboratorymade green pellets, of known composition, under approximately isothermal conditions in a pot grate
