Flotation is a cornerstone of mineral processing, exploiting differences in surface chemistry to separate valuable minerals from gangue. In a typical froth flotation circuit, finely ground ore is ...
Initial open circuit flotation of the 5t sample of near-surface saprolite – which is considered to be representative of Araxá’s mineralisation – produced: a 39.6% Nb2O5 concentrate grade at 54.3% ...
Flotation of zinc ores relies on the transformation of naturally hydrophilic zinc oxides and carbonates into hydrophobic sulphide surfaces that can be selectively separated from gangue. Central to ...
