The depletion of high-grade lead–zinc ore has led to the necessity of developing low-grade lead–zinc ore for the sustainable utilization of lead–zinc resources. A simple method for extracting lead and zinc from low-grade ore that cannot be enriched through flotation was proposed. Initially, the low-grade ore underwent chlorination roasting, followed by leaching …
