The results for the sample roasted at 650°C are given in Table 6, while the results for roasting at 700°C are given in Table 7. It can be seen from Tables 6 and 7 that low-intensity magnetic separation increased the iron grade by about 1.1-1.5% Fe using ore roasted at 700°C and by about 0.66-1.4% Fe using ore roasted at 650°C.
The prime objective of bauxite beneficiation for the metallurgical industry is to reduce the reactive silica content of the ore for lower caustic consumption, and higher alumina recovery. This is followed by reduction in iron content (mainly goethite), organics, boehmite etc., resulting in the overall improvement in quality and increase in ...
