SEDEX: The Biggest Lead and Zinc Deposits in the World

SEDEX: The Biggest Lead and Zinc Deposits in the World. SEDEX (SEDimentary Exhalative) deposits are one of several types of sediment-hosted lead-zinc deposits. Rich accumulations of lead, zinc and silver are found in the ore minerals sphalerite (zinc sulfide) and galena (lead sulfide) deposited between thin layers of marine sand, silt and mud in sedimentary basins.

Mining in Wicklow Mountains National Park

The lead ore was washed in a circular structure known as a buddle. Here the heavier lead settled and the waste (gangue) was washed into slime pits. These pits were checked periodically to collect any lead that may have escaped previous collecting methods. The lead ore was then transported to be smelted.

How can metal mining impact the environment?

Open pit mining disturbs larger areas than underground mining, and thus has larger visual and physical impacts. As the amount of waste rock in open pit mines is commonly two to three times the amount of ore produced, tremendous volumes of waste rock are removed from the pits and deposited in

Mining and Mineral Use

Geologists use many methods to find mineral deposits that will be profitable to mine. Ore deposits can be mined by surface or underground mining methods. Mining provides important resources but has environmental costs. By U.S. law, currently mined land must undergo reclamation. This is not true for old mines. Metal ores must be melted to make metals.

ROMAN BRITAIN MINERAL MINING

Lead Lead was essential to the smooth running of the Roman Empire. It was used for piping for aqueducts and plumbing, pewter, coffins, and gutters for villas, as well as a source of the silver that sometimes occurred in the same mineral deposits. The largest Roman lead mines were located in or near the Rio Tinto (river) in southern Hispania.

History of lead mining

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.
