  • Gold Refining | From Gold Ore to Doré | World Gold Council

    2 天前The Miller process is rapid and simple, but it produces gold of only about 995 percent purity The Wohlwill process increases purity to about 9999 percent by electrolysis In this process, a casting of impure gold is lowered into an electrolyte solution of hydrochloric acid and gold chlorideGold miners too take special care to make the impact of mining for gold as light as possible Reclaiming land to its previous natural state is the final and perhaps9 Step Process for Discovering, Mining & Refining GoldOther process used for a long time is the Wohlwill Process and is considered as the second part of the Miller process due to refine its product This is an electrolytic process based on the dissolution of gold in an acid bath prepared with chlorine gasGold Smelting & Refining Process
