What are the main methods of mining? American

There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.

Mining: Making the Most of Radioactive Caches How

Mining methods depend on the type of deposit, whether it's suspended in water and the geography of the area. For instance, if miners find a deposit sandwiched between layers of rock and water, in-situ recovery will be a more cost-effective option. If experts deal with dry ore, they'll most likely stick with a type of open-pit or underground mining.
