the most popular flotation route in iron ore industry, the direct flotation of iron ox ides still appears desirable for some low grade iron ores that contain a vast amount of quartz. For example, at Republic Mine, Michigan, U.S.A., a hematite ore is upgraded from 36.5% Fe to 65.4% Fe with a Fe recovery of 82.5% using the direct flotation route.
· Samples of water were collected from iron ore mining areas of Tensa region of Sundargarh district. One sample was also collected from Kiriburu iron ore mines of SAIL. The analysis was carried out to determine the effect of iron ore mining on the water quality of the nearby areas of the mine.
· Water quality for flotation on a mine site can vary significantly over time (Levay and Schumann, 2006, Luukkanen et al., 2003, Stén et al., 2003).The composition of flotation water depends on the ore being processed, the reagent suite, the water source and the way the site water system is managed.
Iron ore concentrates can be obtained by the flotation of iron ores providing mixtures containing at least one ether canine of formula (I): R 1 O--(C n H 2n) y--NH--(C m H 2m--NH) x H,. in which R 1 is a linear or branched chain aliphatic hydrocarbon moiety having 6 to 22 carbon atoms and 0, 1, 2 or 3 double bonds; n and m independently of one another represent the number 1, 2 or 3; …
The respective effects of water quality and collector adsorption on ore flotation could not be irrefutably decoupled. However, it could be concluded that of the tested waters, the copper thickener overflow was the least conducive to xanthate adsorption and valuable mineral recovery.
