Research Status and Prospects for the Utilization of Lead–Zinc Tailings as Building Materials

Lead–zinc tailings are the typical solid wastes in mines with high yield and low utilization rates some countries at present. They mainly stockpiled reservoirs, occupying massive land resources threatening health of environment. One advantages building material production sustainability is ability to utilize large amounts industrial wastes, use lead–zinc materials an effective way meet dual needs environmental protection economic development. This paper reviews progress utilizing as summarizes status cement, geopolymer, concrete, brick, foam ceramic. According previous research, contain silica–alumina oxide, which can be used cement clinker. The addition sintered reduce sintering temperature. active components contained concrete instead or preparation geopolymers. Meanwhile, also a fine aggregate. However, there few studies on durability tailings. Additionally, most research results laboratory stage, difficult promoted. In view these problems, corresponding suggestions prospects given end order provide reference for
