Lithium is found in very low concentration in igneous rocks. The largest concentrations of lithium-containing minerals are found in granitic pegmatites. The most important of these minerals are spodumene (Li 2 O, Al 2 O 3. 4SiO 2) and petalite (Li 2 O, Al 2 O 3. 8SiO 2). Spodumene has a theoretical Li2O content of 8.03%. Due to its high lithium ...

2.2. Intensive Grinding with Sodium Sulfide (Na2S) As a grinding additive for increasing the lithium solubility, sodium sulfide (Na2S, SS), was used in this study. SS was prepared from sodium sulfide nonahydrate (Na2S9H2O, 96%), supplied from Junsei Chemical Co., Ltd. (Tokyo, Japan), which was calcined at 120 C for 6 h for dehydration. The

Mixed grinding with Na2S followed by water leaching was performed to extract Li from lepidolite. The leachability of Li increases dramatically in the ground mixture, regardless of the mixing ratio over the range of 1:1 to 3:1, while only 4.53% of Li was extracted in lepidolite ground without Na2S. The leachability increased with an increase of the grinding time, and ultimately, 93% of the Li ...

popularity of lithium can be attributed to an anticipated increase in demand for lithium ion batteries. The most common lithium-bearing minerals occur globally in pegmatites and granites. Spodumene [LiAl(Si 2 O 6)] is the most desirable economic lithium-bearing mineral due to its high lithium content (theoretical Li 2 O content of about 8 wt%).
