Lithium is found in trace amount in numerous plants, plankton, and invertebrates, at concentrations of 69 to 5,760 parts per billion (ppb). In vertebrates the concentration is slightly lower, and nearly all vertebrate tissue and body fluids contain lithium ranging from 21 to 763 ppb. read more
Instead, lithium is usually extracted from lithium minerals that can be found in igneous rocks (chiefly spodumene) and from lithium chloride salts that can be found in brine pools. [4] The largest producer of lithium in the world is Chile, which extracts it from brine at the Atacama Salt Flat. read more
Once lithium's discovery had been announced others soon found it to be present in all kinds of things such as grapes, seaweed, tobacco, vegetables, milk and blood. Another lithium ore is spodumene, which like petalite is a lithium aluminium silicate, and there is a large deposit of this ore in South Dakota. read more
