2020 7 29 around the community residing in the vicinity of the defunct mine Mining has become prominent in this area because of the existence of copper lodes veins and veinlets It was therefore necessary to assess these selected metals associated with copper mining as their concentration has a tendency to affect the environment and human health.
PDFThe Ely Mine which operated from 1821 to 1905 and its area of downstream impact constitute the Ely Copper Mine Superfund site The site was placed on the National Priorities List in 2001 The aquatic ecosystem at the site was assessed using a variety of approaches that investigated surface water quality sediment quality and various ecological indicators of stream ecosystem
2016 1 1 Several critical elements including Re Se and Te which lack primary ores are concentrated locally in some porphyry Cu deposits and despite their low average concentrations in Cu Mo Au ores 100s of ppb to a few ppm about 80 of the Re and nearly all of the Se and Te produced by mining is from porphyry Cu deposits.
