flotation chromite flotation

Flotation of chromite and serpentine - ScienceDirect

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 [5]. Modifying agents may be used to increase selectivity.

Nickel flotation for High Talc Ores - Strategic Met

Flotation of low grade nickel sulfide ores into a concentrate suitable for smelting, and at acceptable nickel recovery, can be challenging. Alteration of the gangue minerals can mean talc is present in considerable quantities. Talc floats naturally and can be very difficult to depress without significant nickel losses. High talc bearing ores have often been considered untreatable.
