Abstract

The activated carbon from the coconut shell can be used as an adsorbent for the recovery of gold. The optimum condition for gold recoverywas obtained at pH 3 (for adsorption) and pH 5 (for desorption) with 1 M thyocyanate solution and a 5 cm length of column (the mass ofactivated carbon is 20 grams). In this condition, the average gold recovery is 90.00%, silver 7.28% and copper 4.93%, that were used severalgold ore samples. The average purity degree of gold is 49.67%, depend on the concentration of gold, silver and copper in the gold oresample.
