奥托昆普公司新开发一种处理富镁硫化镍精矿的冶炼工艺.这种工艺不需要转炉吹炼,不仅大大地简化了工艺流程,而且有利于环保.先在闪速炉中熔炼硫化镍精矿,加入三价铁,降低炉渣溶化温度,把精矿在闪速炉中直接氧化生成品位高于须经转炉吹炼的冰镍,把闪速炉炉渣
Outokumpu has developed a new smelting process for magnesium-rich nickel sulphide concentrate that does not require converter blowing, which greatly simplifies the process and is environmentally friendly. Smelting in a flash furnace Nickel concentrate, adding ferric iron, reducing the melting temperature of the slag, the concentrate is directly oxidized in the flash furnace to produce a grade higher than the ice-nickel to be blown by the converter, and the flash furnace slag
