Trace element distribution patterns in sphalerite and chalcopyrite were studied for the zone refined Sofía D massive sulfide body in the María Teresa deposit which comprises a lower lower portion of dominant pyrite sheathed upward by zones of chalcopyrite Cu zone sphalerite Zn zone and galena sphalerite ± fahlore ± barite Pb Zn Ag zone
Chalcopyrite sphalerite and pyrite trace element contents vary significantly between the metallogenic districts as well as between different ore stages Random Forest discriminates the stratiform sediment hosted Cu Co districts based on trace element geochemistry High Ag and Tl in chalcopyrite is attributed to the Polish Kupferschiefer Ga
Chalcopyrite is the main mineral source of copper ore for extracting and producing copper However with the continuous mining of copper ore the grade of chalcopyrite decreases year by year and its composition becomes more and more complex The traditional pyrometallurgical extraction process has been unable to make efficient use of such resources

Chalcopyrite CuFeS 2 makes up a large and increasing fraction of the world s future copper resources but is highly refractory to leaching with common lixiviants less common reagents recently proposed for chalcopyrite leaching and reviewed here show varying chemical effectiveness and economic potential
Leaching studies of chalcopyrite CuFeS 2 notoriously reach divergent conclusions about kinetics mechanism and passivation behavior during leaching even for the same lixiviant oxidant seldom explored reason for this is likely natural variability in the chemical crystallographic and electromagnetic properties of chalcopyrite samples tested

Chalcopyrite is one of the most important copper minerals; however the extracted efficiency of chalcopyrite is still not satisfactory in hydrometallurgy owing to its high lattice energy which leads to its low dissolution kinetics To overcome the difficulties many advanced technologies have been developed including the selection of high effectively
