Separating them out again can be very hard. In some ways, recycling rare earths from tossed-out items is about as challenging as extracting them from ore and processing them. Rare-earth recycling tends to use hazardous chemicals, such as hydrochloric acid. It also uses a lot of heat — and thus a lot of energy.Web
