Sustainable Mining and Metallurgy

As an important industrial base in China, the accumulation of bulk industrial solid waste in Panzhihua is becoming more and more serious. Its resource utilization is of great significance to promote the development of low carbon building materials and achieve sustainable goals. This paper systematically reviewed the application status of five typical industrial solid wastes, including tailings, smelting waste, coal gangue, desulfurization gypsum and sludge, in the field of building materials in Panzhihua City, and focused on the analysis of their innovative technical paths and application effects in the fields of concrete, brick and composite cementitious materials. On this basis, this paper further reviewed the main problems existing in the current solid waste recycling process, including technical bottlenecks such as insufficient activity of some materials, high cost of large scale application, and high risk of heavy metal leaching. In view of the above problems, it is proposed that the research on efficient excitation and stabilization technology should be strengthened, the application scenarios and market scale of solid waste should be expanded, the ways of resource utilization should be innovated, and the policy support system should be improved, so as to promote the efficient recycling of industrial solid waste in Panzhihua and provide strong support for the realization of the goal of “ dual carbon ”.
