When it comes to purifying gold, there are several methods that can be used. One common method is melting the gold. By subjecting the gold to high temperatures, impurities are removed and the gold becomes more pure. Other methods include using acid treatment, chlorine, or electrolysis. However, melting remains a straightforward and effective approach.
1. Acid Treatment
To purify gold, one must use an acid treatment to dissolve impurities and separate the desired metal. Acid treatment involves using a mixture called aqua regia, which is a combination of nitric acid and hydrochloric acid. Aqua regia is highly corrosive and should be handled with extreme caution.
The acid dissolves the gold alloy, forming gold chloride. Other metals present in the alloy are also dissolved in the acid. However, the dissolved gold chloride can be separated from the other dissolved metals using a solvent called Butyl-Diglyme.
This process allows for the purification of gold by removing impurities and leaving behind the desired metal. It’s important to note that acid treatments involving flammable liquids like nitric acid should be conducted in a well-ventilated area and with appropriate safety measures in place.
2. Using Chlorine
By subjecting gold to a process involving the use of chlorine, the purification of the metal can be achieved. This method, developed by Dr F. B. Miller of the Sidney Mint, involves heating the ore in clay pots and spraying it with chlorine. The impurities in the ore, such as silver, form chlorides with chlorine, while the gold remains unaffected. After a few hours, the molten chlorides can be skimmed off, leaving behind purified gold.
This process results in gold with a purity ranging from 99.6% to 99.7%. The use of chlorine in purifying gold is a critical application in the gold industry. It’s important to note that this method doesn’t affect the flammability of gold. Additionally, the purified gold can be further treated with products like DeoxIT Gold, a contact enhancer, to improve its performance in critical applications.
Using the process of electrolysis, melting gold can effectively purify it. Electrolysis is a technique that utilizes an electric current to drive a non-spontaneous chemical reaction.
In this case, a mixture of hydrochloric acid and gold chloride serves as the electrolyte solution. When an electric current is passed through the solution, gold at the anode dissolves and collects at the cathode. This allows impurities, such as copper and silver, to be removed from the gold.
The cathode, which is made of pure gold strips, can then be melted and cast into bars of high purity, typically 99.5%. The conductivity of gold makes it an ideal metal for the electrolysis process, ensuring efficient purification and the production of high-quality gold bars.
