Hard Rock Lithium Processing - SGS

8.03%. Due to its high lithium content, spodumene is considered the most important lithium ore mineral. A typical run of mine ore can contain 1-2% Li 2 O, while a typical spodumene concentrate suitable for lithium carbonate production contains 6-7% Li 2 O (75% - 87% spodumene). Higher grade concentrates with 7.6% Li 2 O and low iron content are

How Does Lithium Mining Actually Work and Will We Have Enough?

Feb 20, 2018· Still, hard-rock lithium mining can be competitive, at least in mines that are already in operation. Over 145 minerals contain lithium, but only five (spodumene, lepidolite, petalite, amblygonite, and eucryptite) are utilized in lithium extraction. Of those five, spodumene provides the largest proportion of all mineral-derived lithium.
