Lead and zinc mining in Barry County occurred primarily in the 1880s through 1890s, with some production in the 1910s, 1930s and 1940s (IMOP database). There was likely unrecorded production in the 1930s. The primary lead and zinc mining area was the …
Lead is a metal found naturally in the environment as well as in manufactured products. Lead is used in the manufacturing of many items, including glass, rubber, paint, batteries, insecticides, plumbing and protective shielding for X-rays.
Because these waters migrate through underground mine workings before discharging, they interact with the minerals and rocks exposed in the mine. If sulfide minerals are present in these rocks, especially pyrite, the sulfides can oxidize and cause acid rock drainage.
Companies use Lead Mining software to find new business opportunities in their customer databases, sales history information, website visitors, social media following, and more. Lead Mining can help increase the sales team pipeline of deals by finding new leads in existing data or new upsell potentials for existing customers.
The 19th century was a period which saw Cornish mining technology used to deepen some of the mines in search of richer ore deposits. However, as the lead veins narrow with depth, this proved unsuccessful, and attention was switched to resmelting the lead-rich waste slag and slimes left over from previous medieval mining.

Lead for recycling may be in the form of scrap metal (roofing sheet, for example), or compounds of lead, such as the pastes from lead-acid batteries. Clean metallic lead can be melted and refined directly, but compounds and lead alloys require smelting, using processes similar to those used with lead ores.
Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point .
Lead processing either requires the mining of new, primary lead, or the recycling of used products and scrap metals. Both forms of lead must be melted using a smelting process in order to obtain pure and usable forms of the metal.
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 close-packed (hcp) crystal structure and a density of 7.13 grams per cubic centimetre.
Lead is a very corrosion-resistant, dense, ductile, and malleable blue-gray metal that has been used for at least 5,000 years. Early uses of lead included building materials, pigments for glazing ceramics, and pipes for transporting water.
Lead and lead compounds have been used in a wide variety of products found in and around our homes, including paint, ceramics, pipes and plumbing materials, solders, gasoline, batteries, ammunition, and cosmetics. Lead may enter the environment from these past and current uses.
