NEW MANUSCRIPT ON COMBINED EPD&HS TECHNOLOGY FOR MINERALOGICAL RESEARCH IS OUT FOR PUBLISHING IN

Laboratory studies of ore formation and quantitative process mineralogy should include studying all constituents of samples, including accessory minerals on a single grain level. The described technology combines two complementary methods - electric pulse disaggregation (EPD) and our patented hydroseparation (HS). Such combined EPD&HS technology is used as unique solution for mineralogical research of bedrock, ore and processed products. It also includes the following stages of the sample processing and research:

1) mineralogical and geochemical analyses of the primary sample;

2) EPD of the sample (by means of the CNT EPD Spark-2 device);

3) wet screening of EPD products;

4) obtaining heavy mineral concentrates by hydroseparation (by CNT HS-11) from each size fraction;

5) selection of characteristic grains of useful (indicator) minerals from the coarse fractions of the heavy mineral HS-concentrates;

6) monolayer polished sections from all heavy mineral HS-concentrates;

7) mineralogical in-situ investigations of monolayer polished sections of the heavy mineral HS-concentrates and selected characteristic grains by quantitative mineralogical methods;

8) the synthesis and compilation of all information related to research tasks. Combined EPD&HS technology is now used successfully in various research centers and universities around the World resulting in over 300 publications: see www.cnt-mp.com.

The most popular applications of the combined EPD&HS technology are:

I) mineralogical investigation of ores of precious metal deposits, especially gold and platinum group elements (PGE);

II) discovery of new precious metal minerals;

III) study of potentially diamondiferous rocks;

IV) extraction of fine grained particles for geochronology (zircon, baddeleyite, apatite, rutile, Os-minerals and others);

V) use of EPD for paleontology.

VI) EPD recovery of undamaged pristine crystals of gemstones and diamonds
