    Abstract:

    The study of smelting low ferronickel from pre-concentrate nickel-iron ore with 2.76%Ni and 38.00%Fe was carried out to find an effective way for stainless steel enterprises to use the low nickel laterite reasonable. The results show that Ni and Fe have a certain degree of enrichment, and impurities and harmful elements have different degrees of reduction after pre-concentration of nickel iron ore. Most valuable metal did not compound with impurities which greatly accelerated the speed and extent of melt separation reduction. Good alloy of 6.58%Ni with the overall recoveries of 93.38% and 89.95%Fe with the overall recoveries of 89.57% was manufactured under the following conditions: 10% coke, 1.0 basicity, 18% MgO and 3% Al2O3 of slag, melting at 1550℃ for 10min. The product can be used for the feed of producing stainless steel.
