  • Miller Gold Refining Process by Chlorination

    In order to purify gold and remove the silver from it by any process analogous to the cementation with nitre or salt in a reasonable time, the alloy must be in such a fine state of division that the silver will be removed almost instantly, or diffusion must be assisted by actually keeping the alloy in a molten state. Nitric acid, the active ingredient in the first cementation process described
