Abstract The demand for copper is expected to outpace supply in the coming decades due part emergence of wind and solar technologies, which require about five times as much traditional energy sources. This work introduces a potentially transformative hydrometallurgical process extract from chalcopyrite, thereby sustain high rate production throughout 21 st century. Chalcopyrite reacted with van...

Accurate ab initio full-potential augmented plane wave (FP-LAPW) electronic calculations within generalized gradient approximation have been performed for Mn doped ZnSnAs2 chalcopyrites, focusing on their electronic and magnetic properties as a function of the geometry related to low Mn-impurity concentration and the spin magnetic alignment (i.e., ferromagnetic vs antiferromagnetic). As expecte...
