The first step in the production stage is recovering the minerals. This is the process of extracting the ore from rock using a variety of tools and machinery. The second step is processing. The recovered minerals are processed through huge crushers or mills to separate commercially valuable minerals from their ores.

The two main stages in underground mining are development (removing the unwanted and non-valuable rock and other components) and production mining (excavating the target resource.) Depending on the processes employed to recover resources, extraction techniques, and shaft type, there are various categories of …
