Mining waste a new source of lithium

There’s an interesting snippet of information in a Forbes blog written by Tim Worstall. Among a number of positive stories about recent innovations in lithium batteries, Worstall mentions that he is currently involved in a project that: “has managed to work out an economic method of extracting lithium from one of the local minerals.

“It’s a mineral that absolutely no one at present uses, is here in the tens of millions of tonnes and, indeed, there is certainly a good half a million tonnes of it already sitting in old mine dumps.”

One of the potential stumbling blocks of energy storage is the shortage and exhaustion of rare earth elements, as we’ve noted before in Energy Storage Report. So it’s good to hear that an alternative source of at least one essential mineral has been found… and better still that comes from abandoned waste.
