在电炉熔炼铜镍精矿的焙砂时,大约有四分之一的钴量随炉渣废弃(不可回收损失)。用转炉吹炼低冰镍时,进入高冰镍的钴量占23％,在镍电解净液系统给予回收。占钴量52％的转炉渣,需再次返回电炉熔炼处理。由于钴在电炉熔炼和转炉吹炼两个工序形成恶性循环,所以回收率很低。由此可 Approximately a quarter of the amount of cobalt is lost with the slag (irreversible loss) when smelting copper-nickel concentrate calcine in an electric furnace. When using a converter to blow a low-ice nickel, the amount of cobalt entering the high ice nickel accounts for 23% and is recovered in a nickel electrolytic clean-up system. 52% of the amount of cobalt converter slag, to be returned to the smelting furnace. Since the cobalt in the electric furnace smelting and converter blowing two processes forming a vicious circle, so the recovery rate is very low. From this can
