    The Process Of Finding And Refining Raw Gold Nyk Daily

    Jul 31, 2020 The purpose of off-site refining is to expel any remaining impurities from the gold. Off-site refineries achieve this by melting the crude gold then treating it with chloride. Chloride combines with any unwanted minerals or elements and naturally separates from the gold. Refiners expect the gold to be at least 99.5 pure after this process.
