Abstract: 

The Grave granite located in 25 Km Shahindezh from west Azerbaijan and contains 8-12 percent Biotite (Microscopic studies). In this paper biotite separation from mentioned granite have been investigated. Samples were crushed with jaw and roll crusher and rod mill sequentially. Optimum time for communition in the wet rod mill was 10 minutes and about 90 percent of mica (Biotite) grain were freed from other rock - forming minerals (e.g. quartz and feldspar). Mineral processing of -20+40 mesh particles was performed with flotation and shaking table methods and product with Biotite grade of 90 percent and recovery about 57 percent was obtained. The particles of -60+170 mesh were processed by flotation method and the particles of -40+60 mesh were processed by shaking table. The recovery and grade from two different methods were evaluated and results were compared.
