INHIBITION OF THE DEPLETION OF PRECIOUS METAL VALUES FROM PREGNANT LIXIVIANT SOLUTIONS |
摘要 |
<p>Methods for inhibiting depletion of metal values from pregnant lixiviant solutions comprise contacting the requisite metal ore with a prep-robbing inhibition agent (PRIA) comprising one of: (I) alkyl polyglucoside surfactants; (II) imidazoline based amphoteric surfactants; (III) hydroformylation products of lower (C2-C8) alkanes in an organic solvent medium, and (IV) esters and aldehydes. The method is particularly effective in heap leaching of gold with a cyanide lixiviant.</p> |
