Three types of V-Ti (vanadium-titanium) iron concentrate powder were studied on their features as well as their influences on the properties of cold-bonded iron ore pellets. The research results indicated that the relations between the fineness modulus of the three types of V-Ti iron concentrate is in the order of LM>HL>SX, and SX has the smallest fineness modulus and particle sizes. The relations between average wetting speed of the three types of iron concentrate powder is in the order of HL>LM>SX, and the wettability of HL powder is the highest. The relations between mixing time of the three types of iron concentrate powder is in the order of SX≈LM>HL. Under the same briquetting pressure, SX had the best pelletizing performance.
