text: Spodumene, i.e. lithium aluminium silicate, LiAlSi 2 0 6 (Li 2 OAl 2 0 3 -4Si0 2 ), is particularly interesting as a raw material, because its content in ore concentrate is relatively high and the lithium can be easily separated from it, for example, by pressure extraction performed using sodium carbonate, or by using a concentrated mineral acid, such as sulphuric acid.
