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.
Zinc processing, the extraction of zinc from its ores and the preparation of zinc metal or chemical compounds for use in various products. Zinc (Zn) is a metallic element of hexagonal closepacked (hcp) crystal structure and a density of grams per cubic centimetre. It has only moderate

Usually, lead is found in conjunction with other metals such as silver and zinc. Lead materials are mined as a by product of these other more valuable metals. Extracting the lead materials from the ore is a multistep process. First the lead ore is ground into small particles that are less than, giving the ore a texture similar to table salt.
The history of lead and zinc mining in Arkansas is linked because ores of these two metals often occur together. Lead and zinc in Arkansas occur principally along the upper White River and its tributaries in Baxter, Boone, Independence, Lawrence, Marion, Newton, Searcy, Sharp, and Stone counties. Other locations include the Kellogg Mine in Pulaski County and the Ouachita Mountain mineral belt.
Abandoned lead and zine mines and chat piles in Galena, Cherokee County, that have since been reclaimed. In 1870, the discovery of zinc ore in far southeastern Kansas marked the beginning of a century of lead and zinc mining in the Kansas part of the TriState mining district.

Surficial leadzinc deposits in much of southwest Missouri were similar to the surface and nearsurface ores in Washington County. Much of the ore was in clay residuum and near surface bedrock (disseminated and fracture fill), and could be mined by handmining techniques.
China Nerin Engineering said the event – celebrating construction starting on Jiangxi Copper''s leadzincsilver project in the Yinzhushan mining area – took place on June 28 and was attended by various guests from the contractor, mining company and government.
Therefore much lead ore is obtained as a byproduct of other metal mining, usually zinc or silver. Only half of all lead used yearly derives from mining, as half is recovered through recycling, mostly of automobile batteries. Besides the ore itself, only a few raw materials are necessary for the refining of lead.

Zinc 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 ...
