Abstract
A novel method of extracting iron from high-iron red mud and preparing low-carbon cement clinker from tailings was proposed. Thermodynamics of smelting reduction were calculated. The effects of different conditions on iron recovery were investigated systematically. Properties of cement samples prepared from water quenched slag were analyzed. Results showed that increasing temperature, Na2O content and C/S and decreasing A/S appropriately were beneficial to increase the liquid content in slag. Iron recovery was 97.6% under optimal conditions, and the obtained metal met the industrial standard of pig iron for steelmaking. Vitreous content in water quenched slag was 99%, and its pozzolanic activity was comparable to that of S95 grade ore powder. Due to energy consumption and CO2 emission from decomposition of limestone in calcination process of cement clinker reducing significantly, the CO2 emission was reduced to about 400 kg per ton of cement clinker based on the 50% doping amount.
