Mathematical models for froth transportation for the froth and attached particles, including froth velocity profile on the cell surface and residence time distribution of the froth, have been developed for the Outokumpu 50 m3 tank flotation cell used in the primary rougher circuit in the Anglo Platinum Bafokeng Rasimone Platinum Mine concentrator.
A pilot-scale flotation apparatus has been developed for the purpose of determining floatability parameters for an ore.
A special nanobubble generation system has been developed for evaluating the effect of nanobubble on froth flotation.
A single bubble experiment has been developed for the determination of the capture efficiency of particles by bubbles in flotation under well-controlled hydrodynamics and physico-chemical conditions.
A new type of device, a dissolved-air flotation column, was developed for separation of oily wastewater.
semi-batch type flotation column was developed for use as a convenient testing and research apparatus especially in laboratories that do not have sufficient headroom for a full-size experimental column installation.
A liberation/flotation model has been developed to evaluate flotation performance, in which the grade distribution of composite particles is incorporated explicitly.
A new apparatus for electro-flotation has been developed by using the impeller of stirred tank as electrode(s).
A model for a semi-batch flotation separation process has been developed, based on available microprocess probabilities, and compared to experimental data obtained using a WEMCO laboratory flotation cell.
In order to design a flash flotation model, a reliable laboratory method to characterise the response of GRG when subjected to flash flotation conditions has been developed.
