Lithium is a soft, silver-white alkali metal with atomic number 3. As of 2015, the end use of lithium was estimated to be as follows: lithium-ion batteries (35 percent), ceramics and glass (32 percent), lubricating greases (9 percent), air treatment (5 percent), continuous casting mould flux powders (5 percent), polymer production (4 percent), primary aluminum production (1 percent) and other uses (9 percent) (Jaskula, 2014). Lithium is found in brine lake deposits containing lithium chloride and in hard rock pegmatite deposits. It can be sold in a range of product types; as mineral concentrate, brine, compound (lithium carbonate or lithium hydroxide) and metal depending on its intended end use (Goonan, 2012; Jaskula 2014).
