    01/12/2014· Extraction of lithium from a zinnwaldite containing waste was investigated by Jandová et al. (2009). The concentrate (1.40% Li) obtained from dry magnetic separation of the waste (0.21% Li) was treated by the gypsum roast method (with CaSO 4 and Ca(OH) 2). About 96% Li was leached out from the sinter made at 950 °C.
