Cap rock mantled halite diapirs and their surrounding sediments, if calcareous, are often the host of Zn-Pb-Fe-(Ba, Sr) mineralization with <10 7 tons ore at <15% combined Pb + Zn (Zn > Pb) and trace Ag, Cd, ±Hg, ±Cu. From combined field, petrological and geochemical (fluid inclusion, H-, C-, O-, S-, Sr-, Pb-isotopes) studies, mineralization …
Haerdaban is a newly discovered Zn–Pb deposit (0.64 Mt at 6.19 wt% Zn and 1.09 wt% Pb) in the Western Tianshan, NW China. Sulfide mineralization mainly occurs as veins, breccias, and semi-massive ores within the dolomitic limestone and calcareous slate. Here we use Rb–Sr sphalerite and SHRIMP U–Pb zircon geochronology to place …
The western Hunan–eastern Guizhou Zn-Pb metallogenic belt is one of the important Zn-Pb mineralization regions in China. The Dadongla deposit, located in the northeast of Guizhou Province, is one of the typical Zn-Pb deposits in the region and has estimated resources more than 12 million metric tons (Mt) with an average grade of 4.11 …
The results indicated autotrophic bioleaching can solubilize valuable/toxic metals from slag, yielding maximum extraction efficiencies of 90% for Zn, 86% for Cd and 71% for In, although the extraction efficiencies of Pb, As and Ag were poor. The bioleaching performance of Zn, Cd and Pb was independent of leaching system, and leaching …

The Lautenthal sphalerite-galena vein deposit is part of the world-class Upper Harz Pb-Zn-Ag district in the Harz uplift block of the Paleozoic Variscan fold belt in Germany. Its sphalerite-dominated mineral association was studied using bulk-ore chemistry, electron probe microanalysis, and laser ablation-ICP-mass spectrometry. …
From the Middle Ages until the beginning of the twentieth century, extensive Zn–Pb mining and smelting was carried out in East-Belgium. By lack of waste treatment techniques and sustainable management practices, metal-bearing slags and unprocessed waste were dumped in huge tailings, which still represent an important source of …

High-energy electrolytic Zn//MnO 2 batteries show potential for grid-scale energy storage, but the severe hydrogen evolution corrosion (HEC) caused by acidic electrolytes results in subdued durability. Here, an all-around protection strategy is reported for achieving stable Zn metal anodes. First, a proton-resistant Pb-containing (Pb and Pb(OH) 2) interface is …
The Baiyinnuo'er skarn deposit is one of the largest Zn-Pb deposits in northeastern China, with 32.74 million metric tons (Mt) resources averaging 5.44% Zn, 2.02% Pb, and 31.36 g/t Ag. The deposit formed in three stages: the preore stage (prograde skarn minerals with minor magnetite), the synore stage (sulfides and retrograde skarn minerals ...
The Pb-Zn district of the PAZ was exploited in twentieth century. It has produced ca. 400 kt of Zn and 180 kt of Pb (BRGM 1984; Ovejero Zappino 1991).Three types of Pb-Zn mineralization are described in Cugerone et al. ().Type 1 is minor, disseminated, and laminated mineralization, probably associated to sedimentation during …
The Uragen giant sandstone-hosted Zn–Pb deposit has a proven reserve of 5.90 Mt metals in the southern ore zone and potentially 10 Mt metals for the whole deposit, and orebodies are strictly confined to the bleached clastic rocks of the Lower Cretaceous red beds. The bleaching has been used to guide lead–zinc exploration; however, its nature …
The average Zn level is 70.81 ± 28.91 μg g-1 dry weight (DW) in C. rastrospinosus muscle, which is higher significantly than average levels of Cu (0.56 ± 0.41 μg g-1 DW), Pb (0.29 ± 0.33 μg g-1 DW) and Cd (0.12 ± 0.05 μg g-1 DW). Zn and Cd concentrations in the stomach and intestines were significantly positively correlated.
Zn and Pb and an average grade of about 10% Zn + Pb (GT207SGMB 2006). Historical accounts of mining in the DRVD are focused on Zn-Pb deposits occurring as lamellar, banded, and stratiform orebodies in the Neoproterozoic Dengying Formation (Lin 2005a;Wangetal.2014). No sig-nificant base metal sulfide orebodies have been found previ-
Anthropogenic activities release large quantities of heavy metals into the atmosphere. In China, the input of these heavy metals through local and trans-boundary atmospheric deposition is poorly understood. To assess this issue, herein, we use Pb and Zn isotopes to constrain the sources of Pb and Zn in a 210Pb-dated sediment core …
The Sichuan–Yunnan–Guizhou (SYG) Pb–Zn mineral province, which has significant Pb–Zn repositories in China, is situated in the western Yangtze Block. Despite decades of research, the Pb–Zn source of deposits is still disputed between the basement rocks, sedimentary wall rocks, or the Emeishan flood basalts. The newly-discovered …
