Everything You Need to Know about the Gold Smelting Process
The gold ore extracted from the mines has many impurities, including traces of other metals. To separate the gold from these other metals, chemicals such as mercury or cyanide solution should be introduced in the gold. This process leads to gold coagulation, which results in nuggets or clumps of gold.

Gold Ore Grades Explained | PhysicalGold
Gold grade measures the amount of gold within ore before it's processed, while gold purity refers to the percentage of gold in the final, refined product. Gold purity is either measured in fineness (the number of parts gold per 1,000 parts) or gold karats, where 24 karat gold is deemed pure.

Ausome: Non-Toxic Technology Extracts More Gold From Ore …
Traditionally, once gold ore is mined from the ground, it's crushed to a powder and passed through a series of tanks in a process called leaching. Cyanide is then used to separate the gold from the ore into the leached solution. With the new process, the leaching and recovery process is done with chloride, one of two elements in table salt.

How Gold Is Refined: A Step-By-Step Guide
The crude gold is melted and then treated with chloride. This converts any foreign elements or minerals still in the gold into chloride, which will then naturally drift off the gold. The result of this process is 99.5 percent pure gold. The final step is to cast the gold into electrodes or anodes and place them in an electrolytic cell.
