Extraction of Lithium from Lepidolite Using Mixed

This process enables us to extract Li from lepidolite via a water leaching treatment. 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.

Factors affecting the extraction of lithium

01.03.2013  A sulphation roasting using Na 2 SO 4 followed by water leaching process was developed by Yan et al. (2012a) to extract lithium from a lepidolite ore concentrate containing 2% Li and 4.46% F. A lithium extraction of 91.6% was achieved using calcines produced from the concentrate, Na 2 SO 4 , K 2 SO 4 and CaO (mixed at the weight ratio of 1:0.5:0.1:0.1), roasted at 850 °C for 0.5 h.
