An innovative process for the separation of carbonaceous minerals from bulk ores is presented. In this process, the surface of carbonate minerals is reacted with acid used to nucleate CO2 bubbles at the particle solution interface. Entraining the liberated CO2 gas at the surface via coating agent renders the particle more buoyant providing for a...
Flotation behaviour can be controlled, due to diminishment of granula quality and extension of specific surface area, by adding coarse particles (high- grade concentrates) to condition pulp. It has been substantiated that coarse particles can intensify fine particle flotation and its mechanisms are effects of carrier, intermedium and assistant aggregation of coarse particles.
Orebodies at Ok Tedi contain a number of different fluorine bearing minerals. Some of these minerals report to concentrate and are responsible for the presence of the penalty element, fluorine, within the concentrate. Previous analytical work has tended to examine geological samples for content, rather than determine the metallurgical behaviour of the different mineralogical species....
