Electrowinning and smelting are the final stages of gold production The concentrated gold solutions produced in the elution circuit (pregnant eluate and by the Sunrise Reactor, are passed through the electrowinning cells which converts the gold ions (charged gold particles) in the solution into solid goldIn a typical pyrytic gold ore, the gold is encapsulated within an iron sulfide crystal structure Highly oxidized ores generally do not respond well to flotation Advantages of the flotation process are that gold values are generally liberated at a fairly coarse particle size (28 mesh) which means that ore grinding costs are minimized.
