Application Research on Copper Tailings Replacing Sandstone to Produce Portland Cement Clinker
The content of chemical components such as SiO2,CaO,Fe2O3,Al2O3,MgO in copper tailings is relatively high,which is very close to the composition of building materials such as cement,glass,ceramics,etc.After treatment,it can be used as an ideal raw material to replace traditional high-quality calcium and siliceous minerals,and is suitable for industrial reuse in the field of silicate building materials.Based on this,the feasibility of using copper tailings as siliceous raw materials to produce Portland cement clinker was elaborated.
