钼尾矿在建筑材料中的二次利用研究进展

我国是钼资源大国,随着钼矿开采量的逐年增加,产生了大量的钼尾矿,这不仅侵占土地资源,也污染矿区周边环境,因此,尾矿的资源化利用问题己迫在眉睫.钼尾矿作为一种二次资源,具有堆存量大、成分复杂、利用率低等特点;目前在钼尾矿资源综合利用方面,建材化是个重要方向.文章介绍了钼尾矿的矿物组成和化学成分,并综述了国内钼尾矿在砖、陶瓷、微晶玻璃、保温材料、胶凝材料、水泥、混凝土、胶砂等新型建筑材料中的应用研究进展,并论述了钼尾矿建材化过程中存在的问题,提出了建议并展望.

Research progress in secondary utilization of molybdenum tailings in building materials

China is a big country with molybdenum resources. With the annual increase of molybdenum mining, a large number of molybdenum tailing is produced, which not only occupies land resources but also pollutes the surrounding environment. Therefore, the recycling of tailings is an urgent problem. As a kind of secondary development resource, molybdenum tailing has the characteristics of large quantity, complex composition and low utilization rate.At present,Sbuilding materials is an important direction in comprehensive utilization of molybdenum tailing resources.This paper introduces the mineral composition and chemical composition of molybdenum tailings, and summarizes the domestic molybdenum tailings application research progress of new building materials in brick, ceramic, glass-ceramic, insulation materials, gelled material, cement, concrete, mortar, etc. and discusses the problems existing in the process of molybdenum tailings building materials and puts forward some suggestions and prospects.
