摘要
随着矿产资源的不断开发，大量的尾矿被长期堆积，既浪费资源，又带来严重的环境问题。为此，作者对应用金矿尾矿制作蒸压砖的可行性进行了试验研究。结果表明，制得蒸压砖的密度为1900-2000kg／m^3，抗压强度达到国家标准规定的MU15级砖的要求，实现了尾矿的资源化。
With continuous exploitation of mineral resources, resulting in a great quantity of tailings were long-timely accumulated. This circumstance can not only waste mineral resources, but also cause serious environmental pollution. Thus, the feasibility research on preparing autoclaved brick using tailings of gold mines as raw materials is performed. The test results showed that the density of prepared autocloved brick reachs 1900 -2000kg/cm^3, and the pressive strength can achieve the national standard of MU15. The object of resourceful disposal of tailings is realized.
