Ambient Temperature Flotation of Sedimentary

Flotation operations are generally carried out at room temperatures, or at temperatures less than 30 °C. An increasing operation temperature would incur expensive flotation separation, especially for the separation of silicate gangues in the direct flotation process of sedimentary phosphate ores [ 13 ].

Flotation kinetics of a pyritic gold ore - ScienceDirect

2011-1-17  Flotation kinetics of a pyritic gold ore was studied with respect to particle size. Gold recovery increased by 4% with grinding from a P 80 of 205 microns to 53 microns. Second order kinetics is a much better representation of semi-batch flotation. The first order flotation rate constant is independent of particle size in this range. The second order flotation rate constant is more sensitive to variation of P 80.
