Minerals | Free FullText | Flotation of Chalcopyrite and ...
The interaction of OM with sulphide minerals and its effects on their flotation are little understood. Although chalcopyrite recovery and grade are generally high in the flotation of most copper and molybdenum ores, this is not the case for molybdenite, whose flotation is much lower and sensitive to changes in hydrodynamic and pulp conditions in the flotation cell [9,10,11,12].

NEWCREST''S INDUSTRY FIRST APPLICATION ... Eriez Flotation
The HydroFloatTM cell works on combining the principals of flotation with hindered settling. The key characteristic of the HydroFloat™ cell is the presence of an aerated fluidized bed. Using this approach, deslimed, reagentised feed from a classification stage is introduced into the top of the separator via a feedwell

AgglomerationFlotation of Finely Ground .
Agglomerationflotation of a mixture containing chalcopyrite and quartz with 1:1 ratio (w/w, weight by weight) showed that Si recovery in froth was low and did not change with varying conditions (agitation strength, KAX and kerosene dosages); however, Cu recovery was significantly improved with increasing agitation strength, KAX and kerosene dosages, and thus the separation efficiency was improved.
