高镍锍分层熔炼法
layer smelting method of high nickel matte
gaon一el{u feneeng ronglianfa高镇梳分层熔炼法(layer smelting methodof high niekel matte)在高温下添加熔剂熔炼高镍铣使铜、镍组分生成密度不同的产物而得以分离的过程，为高镍镜处理方法之一。 本法始于189。年，是将高铜镍毓与NaZS混合，入鼓风炉在1273K的高温下熔炼。高镍镜中的Cu:S易溶于Na乃形成密度较小(3 3ookg/m3)的熔融体浮在上层;Ni3S:在NaZS中的溶解度小，且随温度降低而急剧下降，形成密度较大(4500一5。。Okg/m“)的熔融体沉于底层。静止冷却后就实现了铜、镍分离。 鼓风炉产出的上层产物进转炉吹炼，得到粗铜和硫酸钠。后者又可用作低层二次鼓风熔炼的硫化剂。在鼓风炉内的主要反应如下: NaZSO‘·7HZO一 NaZSO‘+7HZO个(上部炉料预热) NaZSO‘+4CO一 NaZS+4CO:个(中部NaZSO‘还原) NaZSO4+4C一NaZS+4CO个嘴化区) 上层产物含NaZS 35%一40%、Ni3S:4纬~10肠，呈黑色，冷却时易爆裂;底层产物含Ni声280%~85%、CuZSI%一4%、NaZSS%，呈灰色金属光泽，有一定强度。 本法具有不用焦炭、镍损失少、工艺简单等优点，但劳动强度大，燃料和硫化钠消耗高，当前使用的不多。
