Iron ore flotation Practice, problems, and prospects

Problems or conditions which have militated against a widespread adoption of the flotation process by the iron ore industry, are discussed in contextual relationship to supply, economics, alternatives, and process limitations. Prospects for increased use of secondary flotation are shown to be excellent, but to be less certain for primary flotation.

Froth flotation

Froth flotation

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century. It has been described as "the single most important operation used for the recovery and upgrading of sulfide ores". The development of froth flotation

IRON ORE FLOTATION WITH NONTOXIC REAGENTS K L 1 and E Larsen2,* ABSTRACT The Sydvaranger magnetite mine was shut down in 1996 due to low iron ore prices. It was reopened in 2009. The flowsheet has remained more or less as in the old plant, based upon two grinding steps followed by magnetic separation.

iron ores with a high content of impurities, such as sulfur, have been processed [2]. Pyrrhotite (Fe1 xS) is a kind of common sulde which exists in magnetite ore as an associated mineral with little industrial value. The contamination of sulfur emanating from pyrrhotite in magnetite concentrates has been a problem in iron ore smelting process.

Reagents in iron ores flotation. The degree of neutralisation of the ether amine is an important process parameter. The partial substitution of amine by non polar oils seems to be an attractive route. Part of the amine may be also replaced by polyglycols in its frother role. Starches still represent the most important class of iron oxides depressant.

problem in iron ore smelting process. However, the magnetic separation of pyrrhotite from magnetite is problematic, due to their similar magnetic property and magnetic occulation between pyrrhotite and magnetite [3]. Flotation has been commercially used as a method for removing pyrrhotite from magnetite for high sulfurous iron ores [4].
