Molybdenum tailings are used as the main raw material and a certain amount of fly ash is added to prepare molybdenum tailings sintered brick.The effect of fly ash content on the properties of molybdenum tailings sintered brick is investigated.The results show that the optimum content of fly ash is 6%,the compressive strength of molybdenum tailings sintered bricks prepared under this condition is 25.87 MPa,the flexural strength is 12.85 MPa,the bulk density is 1.83 g/cm3,the water absorption rate is 13.65%,and the ignition loss is 8.17%.All the indexes meet the standards of building bricks.
