Froth Flotation of Iron Ores

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.

Froth Flotation of Iron Ores - sapub

In 1998, three reverse anionic flotation circuits were built in China’s major iron ore area, Anshan. In 2003, these circuits processed 6.77 million tons of iron ore, with a feed grade of 29.9% Fe, a concentrate grade of 67.5% Fe, a tailings grade of 8.31% Fe, and a Fe recovery of 82.1% [51].

In the past, direct flotation methods have been proposed, but presently the one largely employed is the inverse flotation method, in which the quartz gangue is floated, while the iron oxides/hydroxides are kept depressed, with the help of starches (Iwasaki, 1983; Numela and Iwasaki, 1986).
