| Abstract Scope |
Titanaugite particles are main gangue mineral and seriously affected the flotation of fine ilmenite. In this work, the mechanisms of micro-fine titanaugite enter to ilmenite in the flotation was investigated by DLVO theory and Warren method. The Hamaker constant based on the Lifshitz approach was calculated. The result show that it is hard for titanaugite to enter the ilmenite concentrate due to the slime coatings. Entrainment is the main reason that titanaugite enters into froth products. A good separation efficiency for binary mixture of the minerals could be achieved with a 34.52% TiO2 grade and 55.54% recovery in the 3 mg/L sodium silicate. |
