- There are four main mining methods12:
- Underground mining: used to reach deeper deposits, but is more expensive.
- Open surface (pit) mining: typically used for more shallow and less valuable deposits.
- Placer mining: used to extract minerals from loose deposits, such as sand and gravel.
- In-situ mining: used to extract minerals from ore deposits that are still in solid form, such as copper and uranium.
