  • Gold Recovery And How To Choose The Right Process

    Typically, this type of gold is recovered with froth flotation. The gravity flotation combination to recover sulfide associated gold begins the same way as the free milling process, with crushing and grinding. The exception here is that instead of sending the cyclone overflow for cyanide leaching, it is sent instead for flotation processing.
