Gold is one of the natural materials with high value and extensive uses in various industries. To refine gold, different methods can be used, including electrical refining, chemical refining, and mechanical refining.
Components of Gold:
- Gold (Au): The main component of gold, usually making up about 99% of its composition.
- Copper (Cu): This element is often used in higher-quality gold alloys and can make up to about 5% of the composition.
- Other Alloys: Such as nickel (Ni) and zinc (Zn), which may be present in small amounts in gold alloys.

| Element | Typical Composition |
|---|---|
| Gold (Au) | 99% |
| Copper (Cu) | Up to 5% |
| Nickel (Ni) | Less than 1% |
