Apple’s investment in the mining company MP Materials will also help the tech giant reduce its dependence on China for rare earth metals.

Apple has announced a $500 million investment in MP Materials, a rare earth mining company based in the US. With the deal, the two companies will partner on the development of a rare earth magnet recycling line in Mountain Pass, California, allowing Apple to use reprocessed electronics and scrap material to build its products.

Apple has signed a $500 million deal with MP Materials for rare earth magnets, mitigating supply risks after China curbed exports this year and representing a major coup for MP that sent its shares soaring by a fifth.
