However, concentration by gravity machines becomes less efficient as the particle size reduces to finer size. A typical flowsheet used for gravity pre-concentration recovers approximately 45%–65% columbite-tantalite, but significant Ta/Nb losses in gravity tailings occur in the fine fractions and overflow slimes (Bulatovic, 2010). The froth ...
