The desirable area of operation is clearly somewhere in the region where the recovery of cobalt is high, and the recovery of iron to the alloy is still reasonably low. Note that, in actual practice, there is less than 100 per cent carbon utilization, and the carbon addition would need to be somewhat higher than that shown here, because of burn-off of some of the reductant.
