Comparison of environmental performance of modern

All the other species entering the slag concentrator was given the recovery of 6%. The BBR-BCC process was an exception, because otherwise the discharge slag copper would have been too high with these parameters. Thus, the recovery was increased to 93% for all the copper compounds and 20% for the others, resulting in slag with 0.6% Cu.
