Abstract

Abstract

The production of solid waste from non-ferrous metal mining and smelting is large, usually containing multiple heavy metals, which have both environmental risks and resource utilization value. This article established a solution for analyzing the environmental attributes and resource attributes of solid waste through an improved analytic hierarchy process (AHP) and the Topsis calculation method. Combined with the analysis of the composition and structural characteristics of 15 typical solid wastes, the solid waste attribute scores can be quantified, and their treatment paths can be guided. The results showed that the resource attributes of solid waste, such as mining waste and beneficiation tailings were stronger than environmental attributes, and the score of building materials utilization direction was greater than 0.5, indicating a bias towards building materials utilization; the environmental attribute of smelting solid waste, such as waste acid neutralizing slag was stronger than the resource attributes, indicating that its environmental pollution risk was high and must be treated harmlessly; smelting solid waste, such as goethite were rich in valuable metals such as Fe and Zn, and the economic and technological feasibility of metal extraction was high. The resource attributes were stronger than the environmental attributes, indicating its resource utilization approach for metal extraction. The established resource and environmental attributes analysis method can provide important guidance for the treatment and disposal of solid waste from non-ferrous mining, beneficiation, and metallurgy.
