Les mines françaises de plomb et de zinc

Revue géographique des Pyrénées et du Sud-Ouest, 1955
La France possède de très nombreux gisements de minerais de plomb et de zinc. Mais ces gisements, situés surtout dans les terrains métamorphiques des massifs hercyniens, sont d'accès difficile et de médiocre importance ; leur exploitation n'est guère rentable.

History of Zinc Exploration and Mining in Tennessee

1992
Abstract The mining of zinc in Tennessee dates back to 1854 although the presence of zinc minerals had been reported as early as 1844 by Gerard Troost, the first State Geologist. When the Mossy Creek open pit mine, in what is now Jefferson City, Jefferson County, was opened, it became the first mine in what is now known as the Mascot ...

Metal Accumulation by Some Plants Growing on Zinc-Mine Deposits

Oikos, 1977
Zinc accumulation by Thlaspi cepeaefolium (Wulfen) Koch, Biscutella levigata L. and Anthyllis vulneraria L. growing on calamine soils was studied in shoots, leaves and roots at different times during one season. Measurements were made polarographically. A. vulneraria and B. levigata accumulate the highest ammounts of zinc in the roots and leaves during

Nocardia arseniciresistens sp. nov., isolated from lead–zinc mine tailing

International Journal of Systematic and Evolutionary Microbiology
A strain with aerial hyphae presented, designated KC 131T, was isolated from lead–zinc mine tailings, Lanping, Yunnan province, Southwest China. The strain was Gram-stain-positive, acid-alcohol-fast, aerobic and non-motile. Based on 16S rRNA gene sequence and phylogeny analysis, strains Nocardia ninae NBRC 108245T (98.4%), Nocardia alba YIM 30243T (98 ...
