Prior to melting, chalcopyrite is in a strong lattice formation, and is difficult to dissociate. As temperature increases, bond energy decreases, so the decomposition of chalcopyrite requires relatively lower potentials, but efforts for molten-state processing have been hindered by the persistence of high electronic conductivity of chalcopyrite.
