Sediment geochemistry of streams draining abandoned lead/Zinc Mines in central Wales: the Afon Twymyn
Journal of Soils and Sediments, 2010Co-Authors: Patrick Byrne, Ian Reid, Paul J. WoodAbstract:Purpose Despite the decline of metal mining in the UK during the early 20th century, a substantial legacy of heavy metal contamination persists in river channel and floodplain sediments. Poor sediment quality is likely to impede the achievement of ‘good’ chemical and ecological status for surface waters under the European Union Water Framework Directive. This paper exaMines the environmental legacy of the Dylife lead/Zinc mine in the central Wales mining district. Leachable heavy metal concentrations in the bed sediments of the Afon Twymyn are established and the geochemical partitioning, potential mobility and bioavailability of sediment-associated heavy metals are established. Materials and methods Sediment samples were collected from the river bed and dry-sieved into two size fractions (

Application of Lamella Thickener at Huize Lead/Zinc Mines
Yunnan Metallurgy, 1998Co-Authors: Zhang ZhiAbstract:A conventional thickener at Huize Lead/Zinc Mines has been modifed into a lamella one with installation of tilting plates.The laella thickener is used in treating slurry from the second neutralization in Zinc hydrometallurgical plant. It has met the demand of expanded throughput, and improved yield rate of supernatant and quality of electrowon Zinc.

potentially harmful elements and their health implications in cultivable soils and food crops around lead Zinc Mines in ishiagu southeastern nigeria
Journal of Geochemical Exploration, 2019Co-Authors: Smart C Obiora, Anthony Chukwu, G U Chibuike, Alexander N NwegbuAbstract:Abstract This study assessed the concentrations of potentially harmful elements (Cu, Pb, Zn, Mo, Ni, Co, Cd, Cr, Mn and As) in agricultural soils and plants (tubers, fruity and leafy vegetables) and their possible health risk implications on human in the lead-Zinc mining districts of Ishiagu, Nigeria. The concentration of potentially harmful elements in the soils varies according to the order Pb > Mn > Zn > Co > Cu > Ni > Cr > Cd > As > Mo. The potential ecological risk assessments show that the agricultural soils are contaminated by Pb, Zn and Cd and exceeded recommended limits. The concentration of Pb and to some extent Zn, Cr and Cd are higher in the leafy vegetables compared to the tubers and exceeded EU and WHO/FAO maximum allowable limits. Plant concentration factor (PCF) was identified to be higher in Cd, followed by Zn > Cu > Mo > Cr > Ni > Pb > Mn > Co > As. The Daily In-Take of Metals (DIM) values for the PHEs through the ingestion of tubers, fruit, and leafy vegetables were generally below 1; the sequence of DIM values for adults and children for all the plants studied in the order: Zn > Mn > Pb > Cu > Cr > Ni > Cd > As; also, the DIM values were higher for the children compared to the adults, in consistent with the observation of previous workers. The DIM values for Pb, Mn and Cd for all the plants exceeded the USEPA IRIS (2006) threshold limits. The health risk indices indicate that Pb, Mn and Cd contamination in the food crops have greater potential to pose serious health risk to the consumers, including decrease in immune system and dysfunction of vital organs, rise in Pb levels in the blood of children, kidney damage and development of carcinogenic cells in the body, with more prevalence in the leafy vegetables. Development and implementation of effective monitoring and regulation of the activities of mining industries and land use types in the area, massive sensitization campaign for the inhabitants and miners on mining best practices, are recommended for reducing these negative effects of mining in the environment; application of lime-rich soils can be adopted to limit the mobility of the PHEs to some extent.
