US-China trade war opens a market for African rare earth suppliers

Rare earths are minerals used for a variety of military equipment and consumer electronics. China has only a third of the world’s rare earth reserves, but it accounts for 80% of US imports because it controls nearly all of the processing facilities

RARE EARTH MAGNETS HAVE BECOME A COMMON FEATURE IN THE WORLD OF POWER TOOLS.

We generally see two main types of rare earth magnet in use today, neodymium magnets and samarium cobalt magnets. They both come in different grades and have different properties and applications. Neodymium magnets, the stronger of the two, use an alloy that contains mainly neodymium, iron, boron, and varying degrees of dysprosium and praseodymium.
