Title


N.S. RUDASHEVSKY, V.N. RUDASHEVSKY (CNT Instruments, LLC), A.V. ANTONOV (VSEGEI)

The universal technology of mineralogical investigations of bedrocks, ores and processed products

The described technology combines two complementary methods – electric pulse disintegration (EPD) and our patented hydroseparation (HS). Such combined EPD&HS technology is used as unique solution for mineralogical research of bedrocks, ores and processed products. The detailed mineralogical and geochemical investigations of the primary sample and heavy mineral HS-­concentrates of different size fractions are parts of a single 3D-­technology of mineralogical research. Some examples of combined EPD&HS technology application in geology, mineralogy, applied mineralogy and mineral processing for several rocks and ores are briefly described: Pt­-Au­-Pd ores of the Platinova Reef deposit of Skaergaard massif, Greenland, Denmark; Ag-­Au-­Pd-­Pt ores of the Bushveld Complex (chromitites of UG2, LG6, M1/2, Merensky Reef), South Africa; Ag­Au­Pt­Pd mineralization of carbonatites from Kovdor Massif, Kola Peninsula; Ag-­Au-Pt­-Pd mineralization of carbonatites from Loolekop deposit, Phalaborwa Massif, South Africa; 8 new platinum group minerals; Au-­ores of the Berezovsky deposit, the Urals; Au-­Ag-­ores from the Veladero deposit, Argentina; diamondiferous lamproite diatreme, Karelia; microobjects for U­-Pb and Re-­Os isotopic investigations.
Keywords: mineralogical research technology, precious metals, electric pulse disintegration, hydroseparation, kimberlites, lamproites, geochronology, new platinum group minerals.
