Abstract
The present invention concerns a slag composition having a high lithium content, suitable as additive in the manufacture of end-user products, or for the economic recovery of the contained lithium. The lithium concentration indeed compares favorably with that of spodumene, the classic mineral mined for lithium production. This slag is characterized by a composition according to: 3%<LiO<20%; 1%<MnO<7%; 38%<AlO<65%; CaO<55%; and, SiO<45%.
