  • Gold Recovery And How To Choose The Right Process

    Gold deposits can be grouped into two primary classes placer deposits where the gold is exposed from weathering and erosion and hard rock where the gold is still trapped within the host rock. Gold recovery methods for these two types of deposits vary greatly from simple panning to a complex network of grinding chemical leaching gravity

  • Extraction of Gold by Flotation Processcnlitereagent

     · Gold is an easy-floating mineral so extraction of gold by flotation process has always been one of the effective ways to process gold-bearing ores. In primary gold deposits gold minerals often coexist with sulfide minerals such as pyrite chalcopyrite galena and sphalerite.

  • 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.
