  • Placer Gold Recovery Methods

    Placer Gold Recovery Methods

    major flaw of the gravity separation method is that very fine gold, referred to as , flood, or colloidal gold, is lost in processing. Early miners recovered no more than 60% of as sayed gold values, and as late as 1945 recovery of free gold averaged only 7075% (Spiller, 1983). Moreover, it is likely that most remaining placer deposits have a higher percentage of fine gold .

    Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation of gold. It is necessary to determine the suitability of a gravity concentration process before it is employed for concentration of an ore. The concentration criterion is commonly used for this purpose, designated in the following equation (where represents specific gravity): = ( ) ( .
