Froth Flotation of Iron Ores

2/1/2012· Although the reverse cationic flotation route has become the most popular flotation route in iron ore industry, the direct flotation of iron oxides 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

Treatment and Recycling of the Process Water in Iron Ore

The bench-scale flotation tests were conducted in a XFD-63 flotation cell (self-aeration) whose volume for rougher flotation and cleaning flotation was 0.5 L, using 200 g ore at every turn to obtain a Fe concentrate. Fatty acids (RA-715) were used as collector, NaOH was used as pH regulators, starch was used as depressant, and CaO was used as activator. The flotation flow sheet was illustrated

Reprocessing of Sangan iron ore tailings by flotation

The flotation of iron ores is usually performed by reverse flotation using cationic or anionic collectors [17]. The reverse flotation using cationic collectors is the most popular flotation route for the upgradation of low-grade iron ores and iron ore tailings [18, 19]. In the reverse cationic flotation route, after depression of iron

Pneumatic flotation Application of Mineral Processing

The increasing demand for highly enriched iron ore concentrate with low silicate and sulfide content as feed material for pelletizing systems also makes this technology very interesting for iron ore beneficiation. The company carried out a test campaign with its own Hybrid Flotation cell in the laboratory. An iron ore concentrate containing 67 % Fe and 1.3 % S was used as the feed material

Froth flotation Wikipedia

His "Bradford Ore Separator," patented 1853 and subsequently improved, was used to concentrate iron, copper and lead-zinc ores by specific gravity, but lost some of the metal as float off the concentration process. The 1886 patent was to capture this "float" using surface tension, the first of the skin-flotation process patents that was eclipsed by oil froth flotation. It is uncertain if his

Developments in the physiochemical separation of iron

1/1/2015· Two particular items that transformed iron ore processing were, firstly, the use of rod mills for fine grinding and, secondly, the application of the flotation process to separate values and nonvalues. Rod mills were being introduced into all phases of mineral processing and, for iron ore plants, yielded about a 6% increase in recovery, at grade, compared to size reduction equipment in prior
