To get pure gold from jewelry, you can use the Miller process or the Wohlwill process. The Miller process heats gold with gaseous chlorine to remove impurities. The Wohlwill process uses electrolysis, which helps separate gold from unwanted materials. Both methods effectively produce high-purity gold suitable for reuse.
The refining process often begins with melting the gold. Use a furnace to heat the scrap gold until it reaches its melting point. Once melted, pour the gold into a mold to solidify into a more manageable shape.
Next, use a method called aqua regia. This mixture of hydrochloric and nitric acids dissolves the gold, separating it from other metals. After that, filter the solution to capture the gold particles.
Finally, carefully neutralize the acids and precipitate the pure gold from the solution. Wash the gold to remove impurities and then dry it. This final product is pure gold ready for repurposing.
Having refined your scrap gold into pure gold, you can now explore various options. You may consider selling the gold, crafting new jewelry, or investing it in other forms. Each choice opens new avenues for creativity and profitability.
