The present application provides a smelting nrethod of nickel-containing metal, which comprises the following steps: Step1: mixing a low-grade nickel rnaterial with lime and carrying out oxidizing
roasting to obtain ferronickel ore; Step 2: pelletizing the ferronickel ore, first reductant sodium sulfate, water and binder to obtain fen-onickel ore pellets, adding the ferronickel
ore pellets to a rotary kiln, and then mixing in second reductant for prereduction to obtain high-grade feronickel rarv matcrials; Step 3: can')/ing out smelting reduction on the high-gradc ferronickcl raw materials in an SRV to obtain nickel-containing hot metal. The method for efficicntly smelting nickel-containing hot rnetal provided by the present application, by optimizing the rarv rnaterial conditions and pretreatment process, significantly improves them grade of fenonickel in the raw materials charged into the vessel, realizes the low-cost, high-quality and continuous
smelting of nickel-containing hot metal, and can be directly applied to the smelting of
nickel-containing stainless steel in an AOD vessel.
