"Gallium is essential for the production of high-performance chips used in smartphones and tablets, while germanium is required, for instance, for the production of fibre optic cables.
According to Frenzel's estimate, based on comprehensive calculations, the annual global production of gallium and germanium could be at least seven times higher than it is at present. He said: "At least 2,900 tonnes of gallium could be produced every year, while current (2014) production is 440 tonnes. For germanium, current (2014) production is 165 tonnes, while it could be at least 1,200 tonnes."

It's good to know we have enough raw material for future production.
