Iron blastfurnace slag or Pidgeon process' slag was employed as a ffllux in smelting of copper concentrates of a lab-scale.
Results obtained were as follows:
(1) Each slag was very effective as a flux in smelting of copper concentrates. Effective results were obtained with only 10 percent of these fluxes for the concentrates.
(2) Copper yield was 99.1-99. 4 percent in 5-min. smelting at 1, 300°C using 10°C 30% of these fluxes.
(3) increase of silica content in the charge impioved matte grade, though specific gravity of matte decreased and that of slag increased.
