Lithium is the 25th most abundant element of earth’s crust and currently in increasingly high demand with prices rising sharply. It’s well known as a key ingredient in Li-Ion batteries, but is also used for lubricating greases, pharmaceutical purposes, chemical processes, ceramics and glass manufacturing, in air purification, optics, metallurgy and even as a colorant in pyrotechnics. The three largest lithium producers in the world i.e. Australia, Chile, China have a share of approx. 90% leaving Europe dependent on imports. However, several deposits have been discovered in Europe e.g. Austria, Germany, Finland, Portugal, Serbia, Spain, but with the exemption of a small mine in Portugal, they have not been developed yet, largely due to environmental concern and fierce local protests again because of potential environmental damages. There is the need for more environmentally-friendly mining.
