Abstract:The Kivcet process is a modern lead smelting technology suitable for large-scale lead-zinc smelting plants. The process flow of the first domestic Kivcet furnace is summarized and the improvement and optimization of this process in terms of ore drying, material transportation, feeding equipment, automation control and furnace body optimization are introduced, to achieve the goal of introducing this technology from abroad into a green, intelligent and integrated modern industry in China. At the same time, the operation status is briefly analyzed, and through comparison of production technical indicators, it is proved that the Kivcet process has the advantages of strong adaptability to raw materials, stable operation, high metal recovery rate, low cost of treating zinc leaching residue, production safety and environmental protection.
