Abstract In the present study, copper (Cu) and iron boride (FexB) were produced for the first time through molten salt electrolysis using chalcopyrite (CuFeS2) in an oxide-based borax electrolyte. Molten salt electrolysis was carried out at 1073 K and a current density of 600 mA/cm2 for 3600 s under galvanostatic conditions. Cu and Fe/FexB were deposited on the graphite crucible surface used ...
