- 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.

There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. The method used depends on the type of mineral resource that is mined, its location beneath the surface, and whether the resource is worth enough money to justify extracting it.www.americangeosciences.org/critical-issues/mini… - People also ask
