mineral processing kinetics

Flotation Kinetics: Mineral Processing and Extractive Metallurgy .The physical variables that influence the rate of flotation are examined. The probabilistic model of flotation is used to establish the effect of the particle si2e and density, bubble size and agitation on the rate of flotation. In quiescent flotation, it appears that the flotation rate is limited by the particle-bubble collision and.mineral processing kinetics,Flotation KineticsThe ultimate success of the flotation process depends on the capture of hydro- phobic mineral particles by bubbles in the pulp phase and the successful transfer of the aggregate to the froth phase. In the earlier days of flotation, there was con- siderable controversy regarding the mechanism of particle-bubble attachmenr'".

Enhancing process kinetics for mineral carbon sequestration

The current low-cost process for mineral carbonation involves the direct carbonation of a slurry of magnesium or calcium silicate mineral with supercritical CO2. The process is currently limited by the slow reaction kinetics of the carbonation reactions, and in particular the slow dissolution rates of the silicates in weakly acidic.
