Method for thiosulfate leaching of precious metal-containing materials |
摘要 |
<p>A process for recovering a precious metal from a precious metal-containing material, comprising: <SL> <LI>(a) providing a particulate precious metal-containing material; <LI>(b) contacting the precious metal-containing material with a thiosulfate lixiviant and a calcium-containing material; <LI>(c) after the contacting step, forming the precious metal-containing material into agglomerates, wherein the agglomerates comprise particles of the precious metal-containing material, thiosulfate lixiviant, and calcium-containing material; <LI>(d) forming the agglomerates into a heap; and <LI>(e) thereafter passing the thiosulfate lixiviant through the heap to form a pregnant leach solution in which at least most of the precious metal content of the precious metal-containing material is dissolved. </SL></p> |
