Flotation behaviors of ilmenite, titanaugite, and

2015-3-1  For this reason, the flotation behaviors of ilmenite and titanaugite were investigated to improve the flotation recovery of ilmenite. Mehdi Irannajad used a pretreatment method, microwave irradiation, to modify the surface properties of ilmenite, thus improving its flotation recovery in the presence of different gangue minerals including olivine, gabbro, tremolite, and quartz.

Selective flotation separation of ilmenite from

2017-9-10  The flotation separation of ilmenite from titanaugite can be performed using the mixed NaOL-DAA in a wide pH range of 5.0–7.0. In this pH range, the recovery of ilmenite remains constant at approximately 90%, while the recovery of titanaugite remains < 25%. The best separation result can be achieved with NaOL-DAA molar ratios of 10:1.

EFFECT OF OXIDATION ROASTING ON ILMENITE

2014-5-13  The maximum increase in ilmenite flotation recovery was about 50% at pH values ranging from 4.0 to 4.5. After the roasting of ilmenite at 600 °C, ilmenite was floated with a recovery of 91% at pH 6.3. The maximum improvement of recovery at this pH was about 17.5%. In alkaline aqueous solutions, ilmenite flotation recovery was improved slightly.

This is because, although flotation is more rapid and complete with denser pulps, the grade of concentrate becomes lower. It can also be seen that the total iron content gradually decreases with increasing pulp density.
