METHOD FOR SEPARATION IN THE EARTH'S WOMB OF OF FLUORITE RAW MATERIAL INDUSTRIAL BODIES FIT FOR THE PRODUCTION OF OPTICAL FLUORITE |
摘要 |
This method can be used for extracting raw material for use in obtaining synthetic calcium fluorite-based monocrystals, special glasses and ceramics. It provides a precise estimate of the location of technological varieties of fluorite raw materials enabling the calculation of the reserves of industrial categories. The method comprises determining, by means of a mineralogical mapping of the fluorite deposits, including the configuration of X-ray fluorescent spectrums and the sum of trivalent dysprosium and samarium calculated therefrom, the contours of the geological bodies made up of various technological varieties of raw fluorite.
