Study on the Preparation of Carbon-Containing Pellets from the Mixed Ore of V-Ti Iron Concentrate and Titanium Concentrate

The preparation of pellets with taking the iron concentrate and titanium concentrate as the raw materials, the pulverized coal as the reducing agent and the CMC as the binder were researched in this paper. It was deduced from the orthogonal experiment results that the impact of quantities of binders on the compressive strength is the greatest, carbon ratio takes the second place, water content takes the third place, and pressure the least; the impact of the water content on the drop numbers is the greatest, pressure takes the second place, carbon ratio takes the third place and quantities of binders the least. Suitable parameters of forming process are ore ratio is 1:1, quantities of binders is 2.5%, carbon ratio is 18%, water content is 8% and pressure is 16 MPa.
