  • Refining Gold: Remove Zinc by Distillation

    It seems desirable to remove zinc more completely than can be done by acid-treatment, and also to obtain it in a form at once available for precipitation again. I feel safe in saying that from 40 to 50 per cent, of the zinc originally used for precipitation could be thus recovered. Philip Argall says, in speaking of the practice at Cyanide, Colo., upon the Cripple Creek ores: “Our general
