Study of the material composition to develop a rational technology for the enrichment of porphyry copper ores from the Yoshlik I and Kalmakyr deposits

The task of the tests was to study material composition in order develop a rational technology for enrichment porphyry copper balance and off-balance ores Yoshlik I Kalmakyr deposits obtain collective, copper- molybdenum-containing concentrates, finished products form copper, molybdenum pyrite concentrates. ore samples studied using spectral, chemical, assay, granulometric, phase, gold silver, mineralogical, other types analyses. Due absence significant bonds with pyrite, there is no expediency carry out extensive studies hydrometallurgical processing It possible set up basic experiment determine proportion cyanidated gold. When raw materials enriched by flotation, not only various flotation reagents-collectors, technological parameters, but also grinding size are important obtaining concentrate, since required about half cost concentrate.
