Flotation of chromite and serpentine ScienceDirect
Jun 15, 2007· It is well-known that flotation of chromite and serpentine is very difficult, especially in oleate flotation, due to similar surface properties of both minerals and to the ions such as Mg 2+ deriving from the ore and depressing the adsorption of RCOO − ions on the chromite surface . Modifying agents may be used to increase selectivity.
