Kinetic considerations in the flotation of phosphate ore

Advanced Powder Technology, 2005
Abstract A study was conducted on the flotation with oleic acid of sedimentary phosphates from Sierra Espuna, in the province of Murcia (Spain), also comprising an analysis of the kinetic considerations governing the operation. Two different flotation cells were used for this purpose, i.e. a Hallimond tube and a subaeration cell (Denver D-12).

Distributed flotation kinetics models – A new implementation approach for coal flotation

Minerals Engineering, 2014
Abstract Composition-dependent flotation kinetic models with distributed flotation rate constants for predicting the flotation response of the various components of coal have been available for quite some time. However, the full potential of these models have not been realised because the floatability distribution of particles, a key requirement for ...

ABILITY OF KINETIC FLOTATION MODELS TO SIMULATE INTERACTIONS BETWEEN GRINDING AND FLOTATION

Canadian Metallurgical Quarterly, 2005
Pour optimiser globalement les procedes de comminution et separation, les modeles de flottation doivent etre capables de reagir de facon realiste aux changements des proprietes de la population de particules traitee. L'objectif de cette etude est d'evaluer les competences des modeles usuels de simulation de la flottation a reagir aux changements de ...

In-line static mixer rapid flotation system for improved flotation kinetics

Mining, Metallurgy & Exploration, 1993
The US Bureau of Mines investigated rapid froth flotation through more efficient bubble-particle collisions that improved the overall flotation kinetics. An in-line static mixer efficiently mixed the bubbles, water and ore, selectively attaching these bubbles to the hydrophobic mineral’s surface.

Flotation Kinetics of a Pyritic Gold Ore

International Journal of Mineral Processing, 2011
Abstract Kinetics of semi-batch flotation behavior of a gold ore from North-Western Quebec, Canada was investigated with respect to fineness of grind (P80). The gold was mostly associated with pyrite in native form as inclusions and was also in contact with pyrite along the boundaries of non-sulphide gangue.

Influence of flotation cell hydrodynamics on the flotation kinetics and scale up of flotation recovery

2012
Flotation is a physicochemical process and its success is governed by a number of factors; including the ore mineral association and particle size distribution, the pulp chemistry, as well as the hydrodynamics and gas dispersion of flotation machines. Due to the interactions occurring, it is difficult to characterize the effect of a specific factor and
