  • Sub Zero - Gold Refining Forum

    2013-9-12  If what I understand is correct, (the ½ HCL mixed with 16 oz (1 lb) of Sub zero), do you mean that you mixed ½ gallon of HCL to 16 ounces of sub zero. That is about the right mix. You want about 4/1 mix HCL to sub zero (sub zero is about the same thing as sodium nitrate or nitrate of soda. Two things, P111 CPU’s don’t have very much gold.
