refining gold process fire

Oct 09, 2020· Fire assaying involves mixing of the weighed sample of precious metals with a fluxing agent. The use of the fluxing agent here assists in reducing the melting point of the precious metal and removing the impurities present in the sample. A collecting agent, generally, nickel or lead, also gets added along with the fluxing agent.
