In this paper, it is introduced the baking-free high-performance permeable brick is prepared with the process tests of compression moulding and extrusion molding respectively by taking the tailings after beneficiating iron of an abandoned mine in China as the object of study. The blending strategies for compression moulding and extrusion molding processes are put forward. The permeable bricks prepared with the two processes are with excellent properties and could meet the requirements of building materials so that the business cycle of treatment of wastes with processes of wastes against one another is realized.
