Effect of spodumene leaching with sodium hydroxide on its ...
Spodumene exists generally in granite pegmatite deposits, which contain quartz, feldspar, muscovite as well as some tantalite and niobite. Flotation is the most important process to selective separate spodumene from other aluminosilicates (Jie et al., 2014). Since many investigations on flotation of spodumene have been conducted

Fine and coarse fractions of spodumene were obtained from a pegmatite ore and their flotation was investigated under different conditions. In particular, the optimum pH and collector dosage were studied. It was found that the best flotation performance occurs at pH 10 using 250 mg/L of sodium oleate. It was also observed that upon the addition of CaCl2, spodumene flotation recovery increases ...

Spodumene Grinding
In the flotation process, coarse stage grinding minimizes the grinding cost and formation of slimes. In the majority of cases, a grind size (K80) of approximately 200 microns is sufficient for flotation. After primary grinding, mica, if present in an appreciable amount, should be floated to minimize interference with spodumene flotation.
