RECOVERY OF GOLD AND SILVER VALUES |
摘要 |
<p>A method of recovering gold and silver values from a solution obtained as a result of the leaching of a gold and silver bearing ore with a cyanide solution and contacting the solution with activated carbon to adsorb the gold and silver values in solution, the method being characterised by lowering the pH of the solution to a suitable value below 8, generally between 4 and 5, prior to contacting it with carbon and by the contact time being such that substantially all the gold and silver values are adsorbed on to the activated carbon.</p> |
