利用Ni-Fe合金熔体制备镍铁氧化物的方法
摘要：
本发明公开了一种利用Ni‑Fe合金熔体制备镍铁氧化物的方法，其将氧化镍矿经电炉还原熔炼‑精炼脱硫‑转炉吹炼脱杂所得Ni‑Fe合金熔体送喷雾造粒制成Ni‑Fe合金颗粒；Ni‑Fe合金颗粒进一步进行球磨、筛分获得粒径≤25μm的Ni‑Fe合金粉末；Ni‑Fe合金粉末经流态化氧化焙烧制备镍铁氧化物。该制备方法直接采用氧化镍矿冶炼流程的中间产物，具有流程短、能耗低、原料便宜、环境友好的优点。
摘要（英）：

The invention discloses a method of using Ni-Fe alloy melt to prepare iron-nickel oxide, comprising: subjecting nickel oxide ore to reduction smelting by an electric furnace, performing refining desulfurizing, performing converter blowing and cleaning to obtain Ni-Fe alloy melt, and subjecting the Ni-Fe alloy melt to spray granulating to obtain Ni-Fe alloy particles; subjecting the Ni-Fe alloy particles to further ball milling, and screening to obtain Ni-Fe alloy powder having particle size of not more than25 mu m; subjecting the Ni-Fe melt powder to fluidized oxidizing roasting to prepare iron-nickel oxide. The method herein directly utilizing intermediates of a nickel oxide ore smelting process has the advantages of short process, low energy consumption, low material price, and good environmental friendliness.
