Gold tailing and neutralization slag sintered ceramsite and preparation method thereof
The invention provides gold tailing and neutralization slag sintered ceramsite and a preparation method thereof, and relates to the technical field of environmental protection and solid waste comprehensive treatment. The preparation method comprises the following steps: by taking gold tailings as a main raw material and acid mine wastewater neutralization slag as a fluxing agent and a binder, granulating, drying, preheating, roasting and the like to prepare the lightweight ceramsite. The prepared ceramsite product meets related environmental protection requirements of Technical Guidelines for Pollution Prevention and Control for Recycling of Solid Waste (HJ 1091), realizes full resource utilization of solid wastes such as gold tailings and neutralization slag, and has the advantages of excellent performance, high cylinder compressive strength, low water absorption rate and small bulk density. The preparation method has the advantages of high preparation efficiency and low cost, and has good economic benefits, environmental protection benefits and social benefits.
本发明提供了一种黄金尾矿及中和渣烧结陶粒及其制备方法，涉及环境保护与固体废物综合治理技术领域。该制备方法以黄金尾矿为主要原料，配以酸性矿山废水中和渣作为助熔剂和粘结剂，经造粒、干燥、预热、焙烧等过程制得轻质陶粒。制得的陶粒产品满足《固体废物再生利用污染防治技术导则》(HJ 1091)相关环保要求，实现黄金尾矿、中和渣等固体废物的全资源化利用，并且陶粒性能优良，筒压强度大、吸水率低、堆积密度小。该制备方法具有制备效率高、成本低的优点，具有很好的经济效益、环保效益和社会效益。
