Description

technical field [0001] The invention relates to the field of metallurgy technology, in particular to an interval number-based modeling method and optimization method for the whole process of hydrometallurgy. Background technique [0002] With the gradual reduction of high-grade ore, the hydrometallurgical process has begun to be highly valued by countries all over the world. Compared with traditional pyrometallurgy, hydrometallurgy technology has the advantages of high efficiency, cleanliness, and is suitable for the recovery of low-grade complex metal mineral resources. Especially in view of the characteristics of my country's mineral resources, which are rich in lean ore, complex symbiosis, and high impurity content, the industrialization of hydrometallurgy is of great significance for improving the comprehensive utilization of mineral resources, reducing solid waste production, and reducing environmental pollution. [0003] The whole process of hydrometallurgy includes g...
