direct flotation of iron ore

Froth Flotation of Iron Ores

Jan 02, 2012  The history of iron ore flotation started with direct flotation of iron oxides using anionic collectors such as petroleum sulphonate, fatty acids and hydroxamates. In 1950s, the direct flotation route was integrated in plants, including Humboldt Mine (USA, 1954), Republic Mines, (USA, 1956), and Anshan Iron Steel Corporation, (China, 1958).

Reagents in iron ores flotation - ScienceDirect

The role of reagents utilised in iron ores flotation is reviewed. Desliming and flotation stages should be performed at pH levels as low as possible to reduce the expenses with caustic soda. Ether amines are by far the mostly utilised class of collector. The degree of neutralisation of the ether amine is an important process parameter.

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.
