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.

Introduction of lead-zinc ore beneficiation production line: Lead-zinc ore is often symbiosis in nature, and generally beneficiation adopts a combined flotation process. That is, after the ore is crushed to a certain size, the heavy medium is used to remove the large low-grade waste rock, and then the enriched ore is processed by the flotation […]
