A slurry of groundore, water and a weak cyanide solution is fed into large steel leach tanks where thegoldand silver are dissolved. Following this leachingprocessthe slurry passes through six adsorption tanks containing carbon granules which adsorb thegoldand silver. Thisprocessremoves 93% of thegoldand 70% of the silver.

Gold processing-Gold processing-Mining and concentrating: The nature of theoredeposit determines theminingand mineralprocessingtechniques applied. Oxideoredeposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineralprocessingcannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for ...

In cyanidation, metallicgoldis oxidised and dissolved in an alkaline cyanide solution. Whengolddissolution is complete, thegold-bearing solution is separated from the solids. Withoresof highergoldcontent (greater than 20 grams ofgoldper tonne ofore), cyanidation is accomplished by vat leaching, which involves holding a slurry ofore...
