reverse flotation of low grade iron ore in china

An overview of the beneficiation of iron ores via reverse

Despite the recent success of the reverse anionic flotation of iron ores in the Anshan province in China, reverse cationic flotation remains the most popular flotation route used in the iron ore industry ().Comparing reverse anionic and cationic flotation is difficult because the processes are governed by the chemical, physical and metallurgical properties of the iron ores.

Froth Flotation of Iron Ores sapub

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.

Finding baseline flotation parameters for the reverse

Low-grade iron ores are commonly beneficiated by a combination of magnetic separation, gravity separation and direct- or reverse flotation. Fine size iron ore fractions, less than 150 micron, requires flotation to be beneficiated to high-grade saleable iron ore product for pelletizing.

Experimental Research on High Intensity Magnetic

An iron ore contains specularite and hematite which are its main iron minerals and carbonates such as calcite which are its main gangue minerals. The ore is very apt to produce slime in the grinding process,leading to a deteriorated beneficiability. The rough iron concentrate can be obtained by using high gradient magnetic separator to discard tailings with the grinding fineness of 95% -0.074mm.
