A mobile flotation facility, based on two 5 L minicells equipped with on-line monitoring of pH, dissolved oxygen and pulp potential, was used to study flotation of pyrite from zinc concentrate (i.e. reverse flotation) at the Trout Lake circuit of Hudson Bay Mining and Smelting Co. Ltd., Flin Flon, Manitoba. A combination of 2 levels of pH (pH 7 and 5.5 adjusted with sulphur dioxide) and temperature...
The difficulty of density separations at high specific gravities (> 3 g/mL) with conventional heavy liquids has led to the development and refinement of magnetohydrostatic separators. Magnetohydrostatic separation involves the separation of particles on the basis of their relative density (and magnetic susceptibility) in a magnetic fluid acted on by a magnetic field. Most of the research in this...
