  • Mining Of Zinc Zinc Zinc Home

    At first, the zinc ore is crushed in the zinc mining equipment and the zinc ore is miledl after it is moved to the crushing place The raw material used for the production of zinc is zinc concentrate, which is the result of a flotation process after the ore has been mined and crushed The Ore is drilled and blasted in large volumes, transferred to underground rock crushers by large loadersDue to ore body formations, lead and zinc ores are normally deepmined (underground), whereas copper ores are mined in open pits Lead, zinc, copper, and silver are usually found together (in varying percentages) in combination with sulfur and/or oxygen 12182 Process Description2,57 In underground mines the ore is disintegrated byAP42 1218 Leadbearing Ore Crushing and Grinding
