1, professional treatment: When gold jewelry is accidentally contaminated with mercury, the safest way is to send the gold to a professional jewelry store or sales store for treatment. Shopkeepers usually use professional equipment and methods to ensure the safety and integrity of gold.
2. Heat treatment: Another method is to heat gold with a gasoline spray wheel for jewelry processing. Because both mercury and lead have low melting points, they will volatilize at high temperature, thus restoring the original color of gold.
