·Metal mining extraction and concentration need water The recycling of liquid effluents reduces its consumption This recycled water must contain low concentrations of metals This project s first objective was to start up a laboratory scale upflow anaerobic sludge blanket UASB reactor for biotransforming metal sulfates into metal sulfides of effluent from flotation
·In the western Yangtze Block South China Fig 1 a there are >400 Pb Zn deposits hosted in late Ediacaran to middle Permian carbonate rocks Zhou et al 2013a Wang et al 2014 Zhang et al 2015 which form the giant Upper Yangtze Pb Zn metallogenic province Zhou et al 2018a Although the mineralization style of these Pb Zn deposits is
·The IF algorithm is a robust unsupervised anomaly detection method based on an ensemble of isolation trees Liu et al 2008 2012 In these trees subsampled data points are recursively partitioned with axis parallel cuts at randomly chosen partition points between the minimum and maximum values of the randomly selected attributes until all samples are
Distribution of Fe Zn Pb Cu Cd and As from mining wastes and wastewater along a transect of Taxco river in Guerrero Mexico Miriam Mndez Ramírez 1 y María Aurora Armienta Hernández 2 1 Universidad Nacional Autónoma de Mxico Posgrado en Ciencias de la Tierra UNAM CU 04510 Mxico Mxico 2 Universidad Nacional
·The leaching content of HMs As Pb Cu and Zn present in RM FA and CM were extracted according to Chinese standard described in following 1 Preparation of the cement mortar The cement mortar was made according to Chinese standard GB/T 17671 method of testing cements determination of strength State Bureau of Quality Technical
·Intimate knowledge of the mineralogical assembly of the Yushui complex ore rich in Cu Pb and Ag is essential if efficient separation processing is to be conducted With the aid of testing instruments such as scanning electron microscope SEM X ray diffractometer XRD and mineral liberation analyzer MLA combined with energy dispersive X ray analysis
·The Coringa gold silver Cu Pb Zn deposit in southeastern of Tapajós Mineral Province is hosted in felsic volcanic rocks the Vila Riozinho Formation 1996 ± 21 Ma and in the Serra Alkali Feldspar Granite 1999 ± 25 Ma and has been interpreted to have formed in a post collisional volcano plutonic setting The mineralized shear vein
·Trans Nonferrous Met Soc China 31 2021 3530∠3548 Evidence of fluid evolution of Baoshan Cu∠Pb∠Zn polymetallic deposit Constraints from in situ sulfur isotope and trace element compositions of pyrite Jun ke ZHANG1 2 Yong jun SHAO1 2 Ke CHEN1 2 Hua jie TAN1 2 Rui chang TAN1 2 Tian dong ZHANG1 2 Zhong fa LIU1 2 1
·Trace element concentrations in C rastrospinosus in the northern Antarctic Peninsula were ordered from high to low as Zn > Cu > Cd > Pb in the intestine Zn > Cu > Pb > Cd in the stomach Zn > Cu > Cd > Pb in the liver and Zn > Cu > Pb > Cd in muscle Zn content was significantly higher in all tissues by at least one magnitude than other
·Impacts of Cu Pb and Zn on the growth of TSBOI were observed when the sterile liquid media adjusted to various metal concentrations mmol/L since heavy metal concentration is one of the key factors affecting its removal efficiency Representative data are presented in Fig 2 and Table S3 TSBOI showed the best tolerance to
·A dataset of nearly 3600 sphalerite spot analyses from 95 Pb Zn deposits worldwide determined by LA ICP MS was compiled from peer reviewed publications containing 12 elements Mn Fe Co Cu Ga
·From analysis of 52 760 assays from across the deposit it was found that there was a very poor correlation between gold and each of Fe Zn S Pb Cu As and Ag whereas Ag correlated reasonably well with both Pb and Zn Results from EPMA shows that gold varies widely in composition from host rock associated gold 96 wt % Au through more
·The Huangshaping deposit represents the largest Pb Zn polymetallic skarn deposit in the southern Hunan district of Nanling Range South China which is uniquely characterized by having both Jurassic W Sn Pb Zn and Cu Pb Zn skarn mineralization reserves kt WO 3 % kt Mo % kt Pb % kt Zn
·The changes in pH and HA values significantly affected the metal speciation The metals are mainly present as divalent Cd 2 Cu 2 Ni 2 Pb 2 and Zn 2 or trivalent Cr 3 cations species at acidic pH conditions while as metal carbonate for Cu Pb Ni and Cd or metal hydroxide complexes for Zn and Cr at alkaline pH conditions At
·As a result of little attention to the Pb Zn mineralization in the Cu Co Pb Zn system it is unclear about the discrepancy among these deposits The Jingchong Cu Co Pb Zn deposit with reserves of Mt Cu 3718 t Co 12250 t Pb and 72831 t Zn is characterized by lower Cu Co and upper Pb Zn orebodies Wang et al 2017 Wang et al 2022
·Metal pollution in urban soils due to smelting and electroplating has become a severe problem in China In this study the concentration chemical fraction and leaching behavior of typical metals Cu Zn Cd and Pb in soil samples from ten metallurgical sites were studied The results show that some of the soils were polluted with Cu and most were heavily polluted
·The orogenic gold deposits are more common than Cu Pb Zn deposits which implies a more special condition for base metal deposition in the orogenic belt Apart from regional metamorphism and active shear zones there are more prerequisites for the formation of metamorphic fluid induced Cu Pb Zn deposits compared gold mineralization
·Sedimentary basins are highly prospective for a wide variety of base metals and other critical raw materials Hoggard et al 2020 Skirrow et al 2013 and improved mineral exploration targeting in these settings could mitigate future supply chain sediment hosted Mississippi Valley type MVT and clastic dominated CD deposit types
·We conducted batch and column leaching experiments to investigate the removal of Cd Pb Cu and Zn from smelter soil by citric acid The removal efficiency of heavy metals by batch leaching reached a maximum % Cd % Pb % Zn % Cu at a concentration of M and a pH of 5 All of the above mixed solutions were centrifuged
The Kipushi deposit Zn Cu Pb Cd Ag Ge Ga is located in the southeastern part of the copper belt of Shaba It is remarkable for its mineralogical wealth and its economic importance These keywords were added by machine and not by the authors This process is experimental and the keywords may be updated as the learning algorithm
·The exchange kinetics of Cd Cu Pb and Zn in seven mining and smelting contaminated soils and the other two anthropogenically contaminated soils was investigated by using multi elementary stable isotopic exchange kinetic SIEK method and the experimental results were successfully interpreted by modelling using a sum of pseudo first order kinetics
·The Coringa gold silver Cu Pb Zn deposit in southeastern of Tapajós Mineral Province is hosted in felsic volcanic rocks the Vila Riozinho Formation 1996 ± 21 Ma and in the Serra Alkali
