Copper tailing dry desulfurization method, resource utilization method and cement concrete active material
The invention provides a method for removing sulfur-containing impurities in powdery copper tailings in a dry manner, and provides possibility for the powdery copper tailings to be used as a cement concrete active material. According to the method, the copper tailings are pretreated to obtain proper water content and particle size, a proper magnetic field and a proper entering magnetic field are matched, sulfur-containing impurities in powdery materials with low water content and sulfur content are effectively removed and dehydrated, and application of dry desulfurization to removal of the sulfur-containing impurities in the copper tailings is realized. According to a resource utilization method of the copper tailings, based on the desulfurized copper tailings, the desulfurized copper tailings are graded according to the particle size, and reasonable treatment such as modification and grinding is carried out on the desulfurized copper tailings according to the particle size, composition and the like of the desulfurized copper tailings, so that the treatment cost is reduced, and meanwhile, the desulfurized copper tailings are subjected to reasonable resource utilization.
