artical on iron ore reverse floation process

Jan 02, 2012· Althoughdirect anionic flotationwas the first flotation route employed in the iron ore industry, it was later largely replaced by the more efficient reverse cationic flotation route. The application of reverse anionic flotation in China in recent years effectively overcomes some flaws of reverse cationic flotation such as high reagent cost and high metal loss in desliming.

    An overview of the beneficiation of iron ores via reverse

    Mar 10, 2014· The use of frothers during thereverse cationic flotationof iron ores is not a common practice because thepartially neutralised ether mono- and diaminesused as collectors also act as frothers. However, several alcohol-based frothers were used during the reverse cationic flotation of iron ores in the USA and in Canada (Houot, 1983). To stabilise the abundant foam formation, small …

    Mostkinds of minerals require coating with a water repellent to make them float. By coating the minerals with small amounts of chemicals or oils, finely ground particles of the minerals remain unwetted and will thus adhere to air bubbles. The mineral particles are coated by agitating a pulp of ore, water, and suitable chemicals; the latter bind to the surface of the mineral particles and make them hydrophobic.
