In this paper, different doses of sodium hexametaphosphate (SHMP) were added as grinding aids in the process muscovite grinding, and effect SHMP on efficiency was studied. The experiment results show that increases significantly with increase dosage. mechanism improving analyzed by various test methods. Experimental showed when used a aid, ordered structure crystals destroyed, surface roughened...

Mineralogical and chemical analyses of three textural varieties of pyrophyllite samples collected from Baliadihi mine of Keonjhar district, Orissa, India are investigated. Mineralogically they consist of quartz, pyrophyllite, altered feldspar as major minerals and muscovite, chlorite, tourmaline, hematite etc. as minor minerals. The samples exhibit compositional variation of SiO2 65.56 71.66%, ...
