biotite milling operation
. XRD pattern of biotite mineral powder. - Figure 2 of 9 - ResearchGateThe milling was operated in the air with 50 g of mineral biotite per cell and a total of 200 g for 2 h. The average particle size (d80) of biotite was 150 μ m.biotite milling operation,Hard Rock Lithium Processingsuch as spessartine, biotite, pollucite, amphibole and . industries in the design and operation of efficient . maximize milling efficiency, considering both steel.
