Chat Onlinefeed material followed by ore or two stages of recovery. FLOTATION. The flotation process consists of producing a mineral concentrate through the use of chemical conditioning agents followed by intense agitation and air sparging of the agitated ore slurry to produce a mineral rich foam concentrate.
Chat OnlineA froth flotation process is used to concentrate copper ore. It is a two-stage process that involves one rougher stage and one cleaner stage. The cleaner tailings return to the rougher flotation. Both stages are nonreactive unit operations that operate at steady-state.
Chat OnlineThe roasting of an uncyanided flotation concentrate made from the raw ore did not produce a product suitable for cyanidation. Cyanidation of a flotation concentrate made from the raw ore though it would clean up the exposed values was a difficult and costly treatment.
