▎ 摘　　要

NOVELTY - Serpentine is soaked in graphene waste sulfuric acid solution, dissolved, separated by filtration, concentrated by evaporation crystallization, and pH of fractional precipitation solution is adjusted. The resultant material is calcined, and tail gas absorption is carried out. Graphene waste sulfuric acid solution is converted into components such as concentrated sulfuric acid, sulfate, and graphene waste sulfuric acid solution. Serpentine metallic elements are converted to metal sulfate or metal oxides. Serpentine silicon element is converted into porous silica. USE - Processing of serpentine using graphene waste sulfuric acid solution (claimed). ADVANTAGE - The method efficiently provides processed serpentine without affecting the environment. Graphene waste sulfuric acid solution obtained after processing serpentine, can be recycled effectively.
