Froth Flotation of Iron Ores CSIRO Research 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. Fatty

An overview of the beneficiation of iron ores via reverse

Research regarding iron ore flotation began in 1931, demonstrating that reverse cationic flotation is a very efficient method for beneficiating oxidised iron ores. This method can also be applied to reduce the silica content in magnetite concentrates obtained using wet low-intensity magnetic separation. Several studies describing the processing of iron ores via reverse cationic flotation are reviewed. The

Iron ore beneficiation technology, reverse flotation

The reverse flotation process of iron ore is used in iron ore with complex iron mineral composition and high iron grade. It is mostly used to process coarse concentrates of gravity separation and magnetic separation to obtain high-grade iron ore. There are two types of reverse flotation technology for iron ore, one is anionic collector reverse

Froth Flotation of Iron Ores sapub

02/01/2012· The flotation of iron ore started with the direct flotation of iron oxides using anionic collectors, but was latter largely replaced by reverse cationic flotation which has become the most widely used flotation route in the iron ore industry. The successful application of reverse anionic flotation in China’s iron ore industry in recent years offers a good opportunity to reduce costs while increasing iron recovery at the same time since desliming is not essential in the reverse anionic

reverse froth flotation for iron ore vierenmetzorg

Iron ore flotation can be performed in two technical routes: direct flotation of iron oxides and reverse flotation of gangue minerals with depression of iron oxides. Nowadays, reverse flotation is the most commonly used route in iron ore flotation. This review is focused on the reverse flotation of iron ores, consisting of reverse...

Iron ore slimes flotation ScienceDirect

01/10/2010· The relevant responses in iron ore reverse cationic flotation are silica grade and iron recovery in the valuable product. The flotation performance may be controlled via the dosages of amine (collector) and starch (depressant). Low amine dosages are desirable for this reagent is the most expensive. Amine dosage at 30 g/t is a realistic figure for preliminary laboratory tests. A slightly lower dosage (25 g/t) represents an attempt to reduce costs. The high dosage
