mining method selective

Mining method selection is a decision that has a huge impact in every aspect of the mine. Each ore deposit has its own unique characteristics and for that the selection of the optimal mining method is a complex task. There are several factors to be considered in order to make a decision of the mining method to be adopted.

    What are the main methods of mining American

    There are four main mining methods underground, open surface pit, placer, and insitu 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.
