The invention provides a method for evaluating a drying and pre-reducing process of laterite-nickel ore, which belongs to the technical field of metallurgy. The method comprises the following steps of: pulverizing and screening the laterite-nickel ore, adding a carbon reducing agent into the laterite-nickel ore in proportion, mixing uniformly and pelletizing the uniform mixture; and obtaining a flat substance by screening, heating the flat substance to 900-1000 DEG C at the heating rate of 5-30 DEG C/min, simultaneously, introducing an inert protective gas at the flow rate of 0.2-1L/min, cooling the smoke generated by reaction, cooling gas generated after reaction, analyzing the cooled gas by means of infrared analysis to obtain the content of CO/CO2 in the smoke, and calculating the mass loss of the materials. The method provided by the invention has the following beneficial effects and advantages that the mass loss of the materials and the CO/CO2 content change in the tail gas along with the time and temperature are tested by using a thermogravimetric analyzer and an infrared gas analyzer together, and the method for evaluating the pre-reducing process of the laterite-nickel ore is provided; and the pre-reducing degree of the laterite-nickel ore is evaluated to guide the melting process in an electric furnace, so that a production process is more efficient and consumes less energy.
