19.08.2018A process of lithium extraction from spodumene ore has been patented as early as the middle of the twentieth century [ 5 ]. This has led it to be the leader in the commercial mining of lithium rich minerals industry. The former process is still nowadays the most used by companies and is the base of many future spodumene projects.

Spodumene is a fairly prevalent mineral, but mostly dull and uninteresting in its most common forms. However, its two distinctly colored transparent varieties, Kunzite (pink) and Hiddenite (green) are very aesthetic and valued as gemstone s. Hiddenite is much rarer than Kunzite, and can is highly valued, especially the deeper green color forms.

The principal ore for lithium production is alpha-spodumene, which is a lithium aluminosilicate of empirical formula LiAlSi 2 O 6; in its pure form it contains 8% lithium (as Li 2 O) but most productive ore contains much less, typically 1.5–4.5% Li 2 O. The first step is to concentrate the ore to about 90% spodumene by flotation and gravity separation. Australian processing
