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,
