Lead and Zinc - Energy

6.1 Process Overview 6.1.1 Lead and Zinc Ore Mining Lead and zinc ore is nearly always mined below the surface of the ground. Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface. Lead and zinc ore is mined almost exclusively in underground operations, though a few surface operations do exist.

Lead Mines - an overview | ScienceDirect Topics

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.
