Lead-zinc ore is a polymetallic mineral rich in elemental lead and zinc, mainly in lead-zinc sulfide and lead-zinc oxide ore. Among them, lead-zinc sulfide ore is an easy-to-select ore; lead-zinc oxide ore is a difficult-to-select ore. Due to the increasing global demand for lead-zinc mineral resources, both lead-zinc ores are valuable for mining.

Another primary method of lead production is to roast the ore in a reverberatory furnace until part of the lead sulfide is converted to lead oxide and lead sulfate. The air supply to the furnace is then cut off and the temperature rises; then the original lead sulfide combines with the lead sulfate and lead oxide to form metallic lead and SO 2.
