Flotation separation. Flotation is mainly used to separate fine-grained titanium ore. Commonly used flotation reagents are sulfuric acid, tar oil, oleic acid, diesel oil and emulsifier, etc. The beneficiation methods include positive flotation titanium and reverse flotation gangue minerals. Commonly used flotation equipment is a flotation …

Reverse flotation is a process that the gangue minerals report to froth products while the valuable minerals stay in the flotation cell as tailing. According to the types of the collector, it can be generally divided into anionic collector reverse flotation and cationic collector reverse flotation. Reverse flotation has been applied in the ...
The reverse flotation separation of kaolinite and diaspore has been achieved by using the collector dodecylamine (DDA) and depressant cationic polyacrylamide (CPAM) at pH 5.5–8.5. ... pyrophyllite and illite, containing titanium and iron impurities. A unique undesirable feature of Chinese diasporic ores is their low Al 2 O 3 to SiO 2 mass ...
Vanadium titanomagnetite (VTM) is an important mineral for developing titanium resources, but the comprehensive recovery of ilmenite separation is extremely poor, resulting in the low-efficiency utilization of titanium resources. Here, the separation of ilmenite from VTM ore is studied by combining magnetic separation and flotation technologies. In …
For instance, there is a substitution of titanium in the rutile crystal lattice which could occur by iron in the form of isomorphism, making rutile similar to almandine, …
Flotation is one of the most effective technologies for the up-gradation of coal fines of particle size below 0.5 mm because of the inherent hydrophobic nature of coal.Contrary to this, reverse flotation of coal in which coal particles are depressed and gangue particles floated, was developed as an alternative process to minimise the …
High density conditioning in a slightly acid circuit, pH 6.0 to 6.5, with H2SO4, sodium fluoride, and oleic acid actuates the titanium minerals for rapid flotation. This computation effectively rejects the gangue minerals and any apatite. Flotation is in "Sub-A" Flotation Machines with 30-35% solids with fuel oil and a frother added as ...

Flotation work was conducted on two plant samples. The first was a high-titanium product containing considerable amounts of zircon and silica as quartz and aluminosilicates, and the second was a low monazite/zircon material containing high levels of silica. A three-stage process including reverse flotation was developed to treat the first sample.
