Nano-Silica based mineral flotation frother: Synthesis

A Denver laboratory Flotation Cell was used to simulate the flotation process for 22 min according to previously detailed standard flotation procedures (Yang et al., 2013, Cilek and Karaca, 2015). Frother dosages of 10 g/t, 20 g/t and 30 g/t of Nano-silica Frother were employed and benchmarked against the plant or standard frother (SasFroth) at a dosage of 20 g/t and 45 g/t).

2014-4-25  Froth flotation is a widely used process of particle separation exploiting differences in surface properties. It is important to point out that overall flotation performance (grade and recovery) is a consequence of the quality and quantity of the solid particles collected from the pulp phase, transported into the froth phase, and surviving as bubble-particle aggregates into the overflow.
