The beneficiation of lithium minerals from hard rock ores

Jan 15, 2019· In a separate study, the same authors conducted a grade-recovery modelling and optimization of the froth flotation process of a lepidolite ore and showed that at pulp pH of 2 and collector dosage of 500 g/t, lepidolite recovery of 91.51% and concentrate with Li content of 1.96% can be achieved (Vieceli et al., 2016b).

Before both chemical treatments, lepidolite was calcined at 800ºC and was transformed in a more reactive species, β-spodumene. The H 2 SO 4 digestion at 175ºC (followed by water leaching) allowed 88% Li recovery into the solution in 30 min. By the contrary, the HCl leaching process carried out at 90ºC also achieved similar yields but

Factors affecting the extraction of lithium from lepidolite

Mar 01, 2013· The lepidolite concentrate (2.55% Li or 5.49% Li 2 O), which was produced from a beneficiation of the lepidolite ore, was used as the feed material for this study. The XRD pattern of the concentrate in Fig. 1 shows that it contains mainly lepidolite phase (KLi 2 Al 1.128 Si 3.868 O 11 FH) and a minor amount of albite (NaAlSi 3 O 8).The chemical composition of the concentrate measured
