Abstract: In order to explore the comprehensive utilization method of Sifangou tailings,Qinling Gold Mine,tests on the preparation of sintered brick and steam-free and baking-free brick based on the process mineralogical characteristics were carried out.The results show that the composition and particle size of the tailings makes them suitable for brick making;the optimal test conditions for sintered brick preparation are 15 %bentonite ratio,7 %molding moisture,15 MPa molding pressure,10 ℃/min heating rate,1 050 ℃ sintering temperature and 2 h heat preservation time.The sintered brick can reach Grade MU25 and can be used in severe weathering regions;the optimal test conditions for steam-free and baking-free brick preparation are 25 MPa molding pressure,18 % molding moisture,and 20 % cement ratio.The influence of each factor on the compressive strength of the sample is as follows:cement ratio＞molding pressure＞molding moisture.This paper provides a basis and reference for tailings brick making and comprehensive utilization of Sifangou tailings in Qinling Gold Mine.
