This technology breaks through key technologies of blast furnace dust reconstruction and low-carbon reduction by adopting a "multi-component collaboration + multi-scale graded separation" system. Relying on GreenNovo Environmental Technology's "pyrometallurgical enrichment-hydrometallurgical graded extraction" process, it achieves efficient recovery of zinc, indium, and other metals, with a wastewater recycling rate of 95%. It covers five stages: pyrometallurgy, hydrometallurgy, melting, casting, and water treatment, featuring stable processes, high recovery rates, and zero discharge, forming a closed loop for clean resource utilization.
