Froth Flotation of Iron Ores - article.sapub.org

2012-1-2  With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century’s practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore.

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.

The beneficiation of the jig slimes waste from the South African Sishen mine was investigated with three techniques to upgrade it to concentrates suitable for iron making. The slimes were first characterized by chemical, particle size and iron deportment analyses. Three beneficiation routes were then explored: reverse flotation of the as-received slimes, pre-concentration by magnetic ...
