TECHNICAL NOTES 9 FLOTATION - Mineral Tech

Almost all successful models of the flotation process have been based on the premise that flotation is a kinetic process. In this way a model can be formulated in terms of a rate of flotation which can be quantified in terms of some of the many chemical and physical factors that define the environment inside a flotation cell.

feldspar flotation concentrate

The amine flotation of feldspar from magnetite concentrate was investigated using zeta potential measurements, Hallimond tube flotation tests and laboratory-scale flotation tests. The zeta potential of various feldspars (microcline, albite, anorthite, oligoclase and anorthoclase) were determined as a function of pH; the point of zero charge ranged from pH 1.4 to 2.5.

Microflotation tests were carried out using a modified Hallimond tube (Fuerstenau et al., 1957). For these tests pyrite/water suspensions were prepared with one gram pyrite and 100 ml aqueous solution. Prior to flotation, the pyrite was oxidized for 30 min and 24 hs. After this step, the suspension pH was
