In search for an effective method for separation of rutile from its gangue minerals, a combination of magnetic and froth flotation technique was developed [15]. A challenge is always encountered in this separation technique in that, quite often than not, there is always a substitution of titanium in the rutile crystal lattice occurring by iron ...
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.
Sometimes, flotation is used as a subsequent and/or complementary stage in an effort to achieve a cleaner product. For eclogite type of rutile ores, besides …
The micro-flotation tests of single minerals were performed using an XFG-Ⅱ flotation machine (Fig. 2) with the stirring speed at 1750 rpm.The mineral suspension was prepared by adding 3.0 g of rutile (or almandine) to 40 mL of deionized water in the micro-flotation cell.

Pure rutile and almandine mineral had a similar floatability when SPA was used as a collector, and the depressant SF could selectively depress the almandine, while on the other hand, it had a weak depression effect on rutile flotation. Different from other research results, the depression mechanism of SF was mainly due to the fact that SiF 6 2−,
