METHOD OF DETERMINATION OF BENEFICIATION POSSIBILITY OF TIN-CARRYING ORES IN WEATHERING HILLS OF RARE-EARTH METAL DEPOSITS

摘要

FIELD: geology. SUBSTANCE: samples are taken. Contents of lead, barium, tin, bismuth, molybdenum, zinc, wolfram, cobalt, nickel, titanium, magnesium, K₂O, CaO, TiO₂, MnO, MgO oxides, sulfide and colloid tin are found. Coefficients of geochemical zone are calculated by obtained data and degree of benefication possibility is determined with due account of them. EFFECT: decreased number of small-quantity samples and accounting of geochemical characteristics of ores and enclosing rocks when examining rare-earth metal ores in weathering hills and in loose deposits.
