accounted for a increase in the content of iron and a con- siderable reduction in the SiO2 content in the iron con- centrate, while the recovery of the mass and of Fe fell. It is important to add a depressant agent to the iron mi- nerals in the iron ore reverse flotation. In this work, corn starch and CMC carboxymethylcellulose were used.
Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic conditionthat is, the surfaces are either repelled or attracted by water. The flotation process was developed on a commercial scale early in the 20th century to

a good flotation performance at a relatively low temperature of 16 and the adsorption mechanism on quartz surface was established Zhu et al.,2016. However, the effects of -BLA and a-BDA on the flotation behavior of iron minerals had not been investigated, as well as the mechanism of separating quartz from quartz-iron system.
And this will separate the iron ore from other minerals. 4.Drying Since the mineral after flotation contains a large amount of water, it must be concentrated by a concentrator and then dried by a dryer to obtain the dry mineral. Magnetic separation flow chart. Magnetic separation process site
In the flotation separation process of scheelite and calcite, the mixed use of iron ions and depressant TA will improve the flotation separation efficiency of the two minerals. When the dosage of Fe 3 and TA are 1.0 10 4 molL and 5.0 10 4 molL, the recovery of scheelite and calcite are 83.75 and 9.4 at pH 8, respectively.

Jan 02, 2012 Theoretically, iron oxides should be easy to be separated from quartz in direct flotation. However, the presence of hydrolyzable cations in flotation pulp significantly reduces the selectivity of the direct flotation route. The hydrolyzable cations in iron ore flotation pulp are normally calcium, magnesium and iron.

Before strong magnetic and flotation separation, iron ore mining generally uses dry primary process.
Flotation is used to reduce the content of impurities in low-grade iron ores. Iron ores can be concentrated either by direct anionic flotation of iron oxides or reverse cationic flotation of silica, however reverse cationic flotation remains the most popular flotation route used in the iron industry.
