Coconut shell activated carbon For gold mining
In gold minning, activated carbon is used to extract the gold cyanide complex. Coconut shell based activated carbon is excellently suited to this application because of their extreme hardness, excellent adsorption characteristics and good regenerability.
There are several gold processing operations requiring activated carbon:
CIP (Carbon in Pulp): gold pulp is mixed with sodium cyanide, then is contacted with activated carbon in aseries of large agitated adsorption tanks
CIC (Carbon in Column) for Heap leaching: dilute cyanide solution percolate over a heap of crushed ores and is thenpumped through activated carbon columns.
