Abstract: With the traditional production technology and taking Chengchao iron tailings of Wusteel as the main raw materials，black body brick is prepared by adding a mount of self-developed coloring aid additives. So，the effective method of producing low-cost and high-grade building materials is explored. The tests result indicated that under the condition of the ratio of iron tailing to TM of 98.4∶1.6，ball grinding time 36 h，slurry equalizing time 24 h，water adding by 6% in pelleting，pelleting hold time of 48 h，molding pressure 60 MPa and heat preservation for 50 min at 1 180 ℃，the performance of black body brick met the national standards with water adsorption rate of 0.30%，rupture modulus of 69 MPa，damage intensity of 1 503 N.
