PROCESS OF EVALUATION OF MICA-CARRYING CAPABILITY OF MUSCOVITE PEGMATITE Russian patent published in 1997 - IPC

Abstract RU 2096814 C1

FIELD: search and evaluation operations, elaborate prospecting for muscovite pegmatites. SUBSTANCE: evaluation of mica-carrying capabilities of muscovite pegmatites is carried out by measurement of maximum intensities of photoluminescence of ions of bivalent manganese and trivalent iron in samples of feldspar. With satisfaction to inequality J2+Mn

/J3+Fe
 > 0,4 one makes preliminary conclusion on prospects of examined object. Average content of raw material is then calculated by formula and with Ccut.> 16 kg/m3 16.0 kg/cu.m mica-carrying capability of pegmatite veins is estimated as industrially perspective. EFFECT: increased authenticity of equalitative and quantitative evaluation of mica-carrying capability of muscovite pegmatites. 2 dwg , 1 tbl
