    Tailingsfo Dry Stacking of tailings. Dewatering tailings to higher degrees than paste produces a filtered wet (saturated) and dry (unsaturated) cake that can no longer be transported by pipeline due to its low moisture content. Filtered tailings allow better recovery of dissolved metals and process chemicals (e.g. gold and cyanide).

    The cyanidation process was invented in 1887 when the gold recovery started to have some problems due to the lack of good technology. Basically the process is supported by two facts, gold is soluble in dilute solutions of cyanide, and second, the pregnant solution can be processed successfully by using zinc powder or activated carbon and electrowinning .
