Land-based nickel resources include nickel sulfide and nickel laterite, with the consumption of high grade nickel sulfide, usage of nickel laterite received more attentions. The mineralogy and sintering behavior of nickel laterite based limonitic style which has high iron and low nickel and silica was studied to offer an technical support for producing hot metal with nickel through blast furnace route. The result shows that the main phase in this nickel laterite are goethite (FeO(OH)), gibbsite (Al(OH)3) and NiFe2O4. The TG (Thermogravimetric Analysis) and DSC (Differential scanning calorimetry) revealed the removing regularity of free water and hydroxy in the minerals. The yield of the sinter increases from 63.29 to 81.40 with increasing carbon dosage up to 12%, and then decreases when it continuously increases. Similar regularities were found for the strength of the sinter. Magnetite is the main phase in the sinter and kirschsteinite (CaFeSiO4) is the main binder phase.
