Method for improving carbon sequestration capacity of mine tailings, mineralized product and application
The invention relates to a method for improving carbon sequestration capacity of mine tailings, a mineralized product and application. The method for improving the carbon sequestration capacity of the mine tailings comprises the following steps: mixing organic amine and an acid solution to obtain a mixed amine solution, adding the mine tailings, and heating for reaction to obtain mixed slurry; introducing a gas containing carbon dioxide into the mixed slurry, stirring, filtering to obtain a mineralized product and a filtrate, adding amine to improve the carbon dioxide sealing capacity of the mine tailings, and realizing the sealing of the carbon dioxide and the resource utilization of the mine tailings, and further comprising adding an acid solution into the filtrate to form a protonated amine solution, the cyclic utilization of the organic amine solution is realized. The invention also provides application of the mineralized product as a building material, a roadbed material and/or a mine filling material. According to the method, the carbon sequestration capacity of the mine tailings is improved, and sequestration of CO2, resource utilization of the mine tailings and cyclic utilization of organic amine are achieved.
