Nov 10, 2021 For 200 grams of copper or brass pins, you will need 800ml of nitric. From 200 gram plated pins, you can expect 0.5 grams of gold. Or less. Depends on the thickness of the plating and the size of the pins. Thinner pins, bigger yield.

Sep 24, 2021 Kerl states that if all the silver is to be dissolved from gold by one boiling with nitric acid the amount of silver must be at least eight times the weight of the gold. When the proportion, 1:2½, is parted, the resulting gold is left as a porous sponge, if dilute acid is used for the first treatment.get price

Jun 27, 2012 lazersteve. Your nitric acid will be fine for AR, but you will need to adjust the amount used to dissolve the gold. The normal recipie is 4ml:1ml; 31% HCl: 70% Nitric Acid per gram of gold to be dissolved.
