| titleOfInvention | High-low temperature treatment filling method for cyanided tailings |
| abstract | The invention belongs to the technical field of pollutant treatment methods in the field of environmental protection, and particularly relates to a method for treating and filling cyanided tailings at a high and low temperature; the cyanide tailings are dried at low temperature by using a solar greenhouse to remove most of cyanide, then a small part of the cyanide is removed by using a roasting furnace, and the residual heat generated by the roasting furnace is supplied to the solar greenhouse for use, so that the cyanide in the cyanide tailings is economically and effectively removed, the cyanide-removed cyanide tailings and a gel material are mixed and size-mixed for goaf filling, the heavy metal in the cyanide tailings is stabilized and immobilized, the strength and porosity of a filling body are increased, a clean, economic and feasible process is provided for the filling and utilization of the cyanide tailings, and the method has a wide application prospect. |
