The primary lithiumbearing mineral in this ore is usually spodumene, and therefore most of these mines produce spodumene concentrate as the final product. The spodumene concentrate is then usually sold and shipped to lithium hydroxide or carbonate conversion plants, mostly located in Asia, where it is converted to these respective lithium chemical products.

Spodumene has a theoretical Li2O content of %. Due to its high lithium content, spodumene is considered the most important lithium ore mineral. A typical run of mine ore can contain 12% Li 2 O, while a typical spodumene concentrate suitable for lithium carbonate production contains 67% Li 2 O (75% 87% spodumene). Higher grade concentrates

In the complex production required to transform spodumene concentrate into lithium compounds such as lithium carbonate or lithium hydroxide, calcination plays a key role in not one, but two parts of the process, making it an essential technique in efforts to exploit this increasingly important lithium ore. While the beneficiation of lithium from brines has long been the primary focus of

Lithium resources occur in two distinct categories: lithium minerals, largely from the mineral spodumene (Li 2 2 O 2), and salts, largely from lithiumrich brines in salt lakes. Canada, China and Australia have significant resources of lithium minerals, while lithium brine is produced predominantly in Chile, followed by Argentina, China and the USA.

Most lithium is commercially produced from either the extraction of lithiumcontaining salts from underground brine reservoirs or the mining of lithiumcontaining rock, such as spodumene. Lithium production from clay sources is expected to become commercially viable, though perhaps not until 2022.

This is especially so because of the high lithium levels in spodumene as compared to the levels present in brine. The spodumene gemstone price has been increasing by the day. Another advantage is the shortness of time between the discovery of the source of raw materials and the production. Extracting Lithium. The process of obtaining lithium

As lithiumrich brine deposits were developed, the more costly use of spodumene as an ore of lithium declined. At times, the demand for lithium has exceeded what can be produced from working brine deposits. In those times spodumene can become an important source of lithium metal.
