The influence of roasting temperature on lithium, rubidium and iron extraction is shown in Fig. 11. Experiments were conducted at a mica:limestone weight ratio from 2.5 to 5:1. At the 5:1 ratio used by Jandova and Vu (2008) the lithium extraction was <1%. The results shown in Fig. 12 are for a 5:2 ratio, which produced some lithium extraction.
