Short summary
Froth flotation is being tested in Gonçalo pegmatites to produce a lepidolite concentrate. The flotation rejects are mainly composed by a mixture of feldspar, quartz and non-recovered lepidolite (very low content). The scenario could be improved by applying froth flotation also for feldspar/quartz separation: the feldspar concentrate can be used to produce sanitary ware and tiles and quartz for glass and silica flour, reaching an almost zero waste production.
