ABSTRACT. The flotation results show the mixed sodium oleate NaOLbenzohydroxamic acid BHA collectors at a molar ratio of 41 exhibit excellent performance in the flotation separation of ilmenite FeTiO 3 from titanaugite than NaOL alone at pH 6.0.The mixed collectors NaOLBHA increase the contact angle, which improves the minerals surface hydrophobicity and results in
Jun 18, 2014 Therefore, reverse froth flotation tests were conducted in a laboratory Denver cell with a kaolinitic ore. The evaluation of entrainment and true flotation was based on the recoveries of iron, titanium, and manganese oxides FeO, TiO 2, and MnO, and the contributions of each oxide on kaolin minerals determined by electronic microprobe. The ...
In general, the flotation of minerals containing titanium needs to be activated by metal ions due to a lack of activating sites on their surface. However, the activating process is indirectly inferred due to the lack of direct experimental observation. In this study, atomic force microscopy AFM was used to observe the activation process. The results revealed that the hydroxyl compounds

A process as in claim 1 wherein the flotation is performed using a concentrate that is high grade titanium oxide and flotation tailings that are insolubles. 15. A process as in claim 14 wherein the flotation concentrate is subjected to liquid-solid separation, calcining, size reduction and screening to produce various grades of titanium oxide ...
In this second part of the Review on foam and froth flotation, many other aspects of the flotation process are examined, referring mainly to the separation of particulate matter.
Mar 01, 2020 An XFG-type flotation machine Changchun, China was used for the flotation test. Either 2 g of a single mineral powder or 6 g of mineral powder mixture 3 g of ilmenite and 3 g of titanaugite was added to a flotation cell containing 40 mL of DI water .After stirring for 2 min at an impeller speed of 1700 rmin, the NaOL was added to the cell and agitated for 2 min.

China is rich in titanium resources, which accounts for more than 35 of the world. But, until today, the industrial TiO 2 recovery for ilmenite ore is slightly higher than 30 in the current pulsating high-gradient magnetic separation-flotation process HGMS so that a large amount of ilmenite value were lost in tailings. A centrifugal HGMS CHGMS method was introduced and

Rutile may be separated from ilmenite or ilmenite ores by agitating a mixture of ilmenite and rutile in particle form in an aqueous solution containing a collection agent to which hydrogen peroxide has been added. The slurry in agitated form is treated with air to produce a froth. The ilmenite particles will attach themselves to the air bubbles in the froth and may be skimmed off
