Combined EPD&HS Mineral Processing Lab
 |  |
EPD&HS Mineral Processing Lab is:
- ideal extraction and perfect separation of mineral constituents from any rock/ore type or processed product regardless of density, hardness, abrasiveness or grain size;
- pristine undamaged crystals and mineral grains extracted from any sample;
- practically no loss of accessory minerals, regardless of their grain size;
- representative heavy mineral concentrates from 100 to 10,000 times the original proportions of the desired minerals from small (100 g to 3 kg) or large (up to 200 kg) samples;
- no use of hazardous chemicals, no dust; only water and electricity are consumed during mineral processing;
EPD&HS Lab is used to:
- study the crystal morphology, mineralogy and mineral chemistry of PGM, gold, base metals and other useful constituents of different rock types containing low concentrations;
- enhance the chances of finding well formed grains and crystals of accessory minerals for their identification and characterization (e.g. PGM, gold, diamond, zircon, baddeleyite, etc) (Figs. 1-3);
- carry out prospecting and technological mapping at the phase level from small samples (100-2000g);
- produce ultraclean separates of accessory minerals for any analytical purpose (i.e. mineral identification, isotopic studies, X-ray diffraction etc.) without using toxic chemicals and reactants which may leach or crush desired minerals;
- determine the identity of accessory minerals, their grain-size distribution and mineral associations; important information for economic evaluation and extraction;
- detect the occurrence of useful minerals and elements in possible secondary mineral deposits (process products such as mine tailings, industrial slags, etc);
- separate intact crystals and/or crystal fragments of various precious and semi-precious stones;
- contribute to better understanding of the paragenesis of deposits through detailed studies of accessory minerals;
- conduct analysis of losses in tailings from concentration mills, etc
