Lead and zinc ores often occur together, and there are a large number of countries that mine and process lead ore, making it among the most widespread metals in terms of primary production (Kesler, 1994). Most of lead mining is done by highly mechanized underground methods, although some deposits are mined from open pits.
The Tsagenbulagen deposit is located approximately 6 km southeast of Jiawula and represents one of the largest Ag-Pb-Zn deposits in Northeast Asia. Ore at Tsagenbulagen shares the same geological setting as the Jiawula and Tsav deposits and belongs to two independently produced silver polymetallic ore deposits within the same ore field (Nie et ...

Carbonate Replacement Deposits (CRDs) are geological formations that result from the replacement of pre-existing carbonate rocks by ore minerals, often metals such as lead, zinc, and copper. These deposits are significant sources of base metals and are of economic importance due to the concentration of valuable minerals within them.
Sediment-hosted Pb-Zn deposits contain the world's greatest lead and zinc resources and dominate worldproduction of these metals. They are a diverse group of ore deposits hosted by a wide variety of carbonate andsiliciclastic rocks that have no obvious genetic association with igneous activity. A range of ore-forming processes in a variety of geologic and …

4.3.1 Type of Lead Ore Deposits. Lead deposits are members of a class of ore deposits known as the "hydrothermal" deposits, in which metals were initially leached by hot highly saline aqueous fluids in the subsurface of the Earth's crust and transported to the site of deposition. Lead and zinc are often found together in ore deposits ...
The metallic lead and zinc in MVT ore deposits are chemically bonded with sulfur to form sulfide minerals. The ore deposits were formed as sulfide mineral crystals precipitated from the hot brines on the walls of open, vertical fractures (cracks) in carbonate rocks below the surface. As crystal growth continued, all open space was filled,
