Gold is purified primarily through a process called smelting, where raw gold ore is heated to high temperatures to separate impurities. Another common method is cyanidation, where gold is dissolved in a cyanide solution and then extracted through electrolysis or carbon adsorption. Additionally, a technique known as cupellation can be used, where ores are treated at high temperatures with lead, allowing impurities to be removed. Each method aims to achieve a high purity level of gold, often exceeding 99.9%.

How do you purified gold?
Gold can be purified through a process called electrolysis, where an electric current is passed through a gold-containing solution, causing the gold to plate onto a cathode. Another method involves using a mixture of hydrochloric acid and nitric acid to dissolve impurities in the gold, with the pure gold remaining in solid form after the acids are neutralized.

What happens when gold is treated with Mercury?
When gold is treated with mercury, it forms an amalgam. This process is often used in gold mining to extract gold from ore. The amalgam is then heated, causing the mercury to evaporate and leaving behind the purified gold. However, this method is hazardous due to the toxicity of mercury.
