    The Borax Method of Gold Extraction for SmallScale

    Jun 01 2012 Methods. Borax was added to milled ore to reduce the melting point of gold to a level accessible to SSM. The amount of gold captured and the amount of mercury released into the environment was compared to two common amalgamation methods whole ore and heavy metal. Discussion. The borax method appears to capture more gold as well as eliminate.

    Gold Refining From Gold Ore to Dor233; World Gold Council

    Aug 08 2021 The two gold refining methods most commonly employed to derive pure gold are the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple but it.
