Determination of surface chemistry and flotation

Flotation is a standard method used to recovery rare earth minerals from complex, magmatic and hydrothermal deposits (Romero and Mccord, 2012, Khanchi et al., 2014). Allanite is a rare earth silicate mineral found in the epidote mineral group. The general formula of allanite is A 2 M 3 Si 3 O 12 [OH].
