Method for grinding and delaminating muscovite
After this step, the muscovite was concentrated by table gravity concentration (a wet method). In the second dry grinding step a steel-coated laboratory knife-mill (EXPERT) equipped with four rotating knives was used. The material was ground in a batch circuit (50 g, 10 min) and dry sieved under 100–45 μm.

DMS exploits the difference in specific gravity between the target and gangue minerals, and is commonly used in the separation of spodumene from other gangue silicates. The specific gravity of spodumene is between 3.1 and 3.2; this makes it slightly heavier than most gangue minerals such as quartz (2.65), albite (2.60) and muscovite (2.8).
