Role of silica and alumina content in the flotation of ...

2016-3-10  In reverse flotation, the removal of silica from iron ores is typically carried out by amine based collectors. Reagents such as dodecylamine, ether amines, ether monoamines, di-amines and quaternary ammonium salts are used in cationic flotation (Ma et al., 2011, Vieira and Peres, 2007).

Iron Ore - Clariant Specialty Chemicals

The FLOTIGAM® series includes ether amines, ether diamines and other cationic collectors for every iron ore flotation challenge. Our FLOTIGAM® collectors are able to produce iron ore concentrate with low silica content by froth flotation, resulting in high purity concentrate, which is needed for steel production.

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.

Froth Flotation of Iron Ores - Publications

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.
