Five Steps for Solving the Rare-Earth Metals Shortage | BCG
The rare-earth industry can be divided into three stages: upstream, or the mining of elements; midstream, the processing of elements into separate oxides; and downstream, the manufacturing of permanent magnets and other components made with rare earths. Making rare earths globally available starts in the upstream stage.
