Quarrying Processes Of Lead Zinc Deposit
: Mineral Resources
The most active hydrothermal process today produces volcanogenic massive sulfide (VMS) deposits, which form from black smoker activity near midocean ridges all over the world, and commonly contain copper, zinc, lead, gold, and silver when found on the surface . The largest of these deposits occur in Precambrian age rocks.

Metal Deposits – Physical Geology
Mining and Mineral Processing. Metal deposits are mined in a variety of different ways depending on their depth, shape, size, and grade. Relatively large deposits that are quite close to the surface and somewhat regular in shape are mined using openpit mine methods (Figure ). Creating a giant hole in the ground is generally cheaper than making an underground mine, but it is also less ...
Mining in Ireland
This period also witnessed the most important episode of coal mining, slate quarrying and pyrite production in Ireland. Today, Ireland is internationally renown as a major zinclead mining province. Over the last 40 years a string of significant base metal discoveries have been made, including the giant ore deposit at Navan (>70Mt).
