Rare Earth Mining: The Dark Underside of

2021-4-20  Rare earth minerals are a highly valued commodity. China currently controls 80% of the world’s resources and refines most of the rare earth minerals mined in the world. This in and of itself is not an issue unless rare earth minerals become politicalized, which occasionally they do. In 2010 China restricted rare earth mineral shipments to Japan.
