  • Melting and Refining of Gold Home Springer

    CHAPTER 11 Melting and Refining of Gold Refining of gold comprises the following sequence of operations: melting, refining, degolding, and electrorefining Melting goldBut the metal is a crude metal; hence a refining procedure is necessary to get pure metal The extraction of metal also needs proper refining to remove the impurities which a metal absorbs through all the chemicalbased procedures An electronic refining apparatus is used for the refining procedure, which provides 999% pure metal Conclusion:Extraction of Metals – Concentration, Reduction and Refining
