Get PriceLead 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.
Get PriceThe earliest period of lead mining in Kansas was probably in Linn County in the 1830's, but the first commercial production of lead in the state was near Galena in 1877 (Schoewe, 1958, p. 418421). Nearly all of the lead and zinc was won by underground mining methods; however, some strip mining of the ores was tried in the Galena area.

The Broken Hill silverleadzinc ores are probably the most famous in Australia, and have particular significance in mineral processing as it is these sulphide ores which provided the impetus (in the early part of last century) to develop an industrial flotation practice. ...
Get PriceZinc mining is the process by which mineral forms of the metal zinc are extracted from the earth through mining. A zinc mine is a mine that produces zinc metal. Some mines produce primarily zinc, but some mines produce zinc as a sideproduct of some metal that has a higher concentration in the ore. Most zinc mines produce zinc and lead or zinc ...
