gold plants where uranium and gold are recovered from the same milled ore. Uranium is leached in acidic solution (pH 1 to 2), and any aurocyanide pre­ sent in solution in the feed to the uraniumleaching plant will precipitate as AuCN, and will be lost with the solid residue from the plant. This has been a major impediment to the development of processes for the simultaneous leaching of gold ...
