mining - Students | Britannica Kids | Homework Help

The crude run-of-mine mineral must be processed to separate it from impurities such as mud, waste rock, or mixtures of other minerals. This procedure, called ore dressing, also serves to increase the mineral content of the ore before it is sent to the smelters. The resulting mineral is called a concentrate.
