Gold Parting using Nitric Acid
24/03/2016 · The process of parting gold with nitric acid is old, and probably dates from the discovery of nitric acid itself; it is one of the simplest parting processes, and does not require a costly plant or much manipulative skill. The main objection to it is the cost of the acid. The operation comprises the preparation of a suitable alloy.
