The invention aims at features to the lead-and-zinc tailings and provides a method of manufacturing steaming-and-pressing silicate wall materials, wherein the features include low content of silica, large density, coarse granules and the like. The method of manufacturing silicate bricks with lead-and-zinc tailings has the advantages that the lead-and-zinc tailings with high true density, containing a certain number of coarse granules and high bulk density is used and can be used for aggregates of the silicate bricks with good effects of moulding pressure transition and beneficial for compression moulding. High compression moulding density can be obtained. The defect that the content of the silica in the lead-and-zinc tailings is not enough can be overcome through adulteration partial ground fine quartz sands. The method of manufacturing silicate bricks with the lead-and-zinc tailings is a processing method of the lead-and-zinc tailings that the technology is simple and the cost is low.
