【 摘 要 】

The results of studies of the cyanide and an alternative methods for leaching gold and silver from oxidized ores of the Malmyzh field are presented. The possibility of recovering gold and silver from oxidized porphyry copper ores by thiosulfate solutions in agitation and percolation modes without intensifying the process – heating the solutions and adding copper ions – has been shown. Also, in a separate cycle – copper leaching with low-concentration sulfuric acid-sulfite solutions with additional opening of the silicate matrix with ammonium hydrofluoride – has been studied. The possibility of using ammonia-thiosulfate leaching in percolation mode has been investigated.
