what type of mining are to remove silver from the earth

There are four main mining methods:underground, open surface (pit), placer,andin-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.
