In view of the difficult problem that vanadium tailings slag has low ridges and cannot be applied to the field of vacuum extrusion plates,this paper mainly selects a plasticizer formula through the screening of fi-bers,water-retaining agents and plasticizers,and through orthogonal experimental design,range analysis and effect curve analysis.After the application of this formula,the plasticity index of vanadium tailings raw materi-al IP=13.1 can be made to meet the requirements of vacuum extrusion process.
