Barium sulfate waste residue comprehensive utilization method and wall filling material
The invention discloses a new process aiming at recycling treatment and comprehensive utilization of barium sulfate waste residues, and is suitable for all barium salt production manufacturing industries. The process has the main innovations that sintered ores and symbionts in the waste residues produced from production of barium sulfate are stripped for the first time, the waste residues are sorted according to the difference of densities of components, and barite and coal which are not reacted completely are recycled and return to a furnace for reuse; the barium sulfate content of the recycled barite component can reach more than or equal to 80%; and the rest of the residues after harmless treatment are used for preparing an energy-saving wall filling material-a foam concrete block having a radiation protection function. The process not only solves barium sulfate waste residue accumulation and land occupation and various pollution problems on the environment but also recycles the barite and coal which are not reacted completely, besides, makes full use of the radiation protection performance of barium, prepares the novel radiation-protection foam concrete block, saves energy, protects the environment, achieves the purpose of comprehensive utilization of resources, and thoroughly solves the solid waste emission problems in the barium salt production industries.
