Black shales are sedimentary rocks containing >0.5% of organic carbon. They host polymetallic deposits which have been mined for Cu, Ni, Zn, Mn, P, Mo, V, U, Au and PGE (platinum group elements). Even sub-economic occurrences provide potential risk acid rock drainage when exposed to oxic surface environment. The natural neutralisation varies depending on the adjacent units, especially presence calcareous rocks. chemical mineralogical composition black shale is reflected in quality waters...
Chronic exposure to arsenic may be detrimental health. We investigated the behaviour, remediation and risk management of in Freiberg, Germany, characterized by past mining activities, near Verdun France, where World War I ammunition was destroyed. The main results included: (1) pot experiments using a biologically synthesized adsorbent (sorpP) with spring barley reduced mobility arsenic, (2) Omega-3 Index ecotoxicological tests verified that sorpP uptake toxicity plants, (3) reverse osmosis...
The Talvivaara deposit is hosted by metamorphosed black shales (black schists) and contains 300 million metric tons (Mt) of low-grade ore averaging 0.26 percent Ni, 0.14 Cu, 0.53 Zn. As a result tectonic deformation, the horizon containing > or = 0.8 Ni-Cu-Zn up to 330 m thick. situated in Early Proterozoic Kainuu schist belt, which consists mainly metasediments, with discontinuous serpentinite remnants 1.97 1.96 Ga age. Serpentinite-associated Cu-Co-Zn-Au-Ni deposits prospects Outokumpu...
Arsenic concentrations in soil and water were examined at the European level via a literature review data inventory first phase of AgriAs Water JPI project. can be derived from both natural anthropogenic sources. At scale, distribution arsenic agricultural topsoil mostly explained by geology. In next step, project investigated two regions: Saxony Germany Verdun France. The results compared with geogenic region around city Tampere Finland. Saxony, is partly widespread mining ore processing...
The Outokumpu Cu-Zn-Co deposits are associated with serpentinites, interpreted as ophiolitic. serpentinites surrounded by dolomite-rich rocks, calc-silicate fine-grained quartz metamorphosed black shales (black schists), and mica schists. ore is hosted mainly but also rocks Calc-silicate anomalously enriched respect to Ni Cr. original reserves in the area were 50 million tonnes (Mt) sulfide grading 1.2 3.8 percent Cu, 0.6 1 Zn, 0.1 0.2 Co, Ni, 0.8 g/t Au, 9 Ag.Black schists...
ABSTRACT Suitability of the PicoTAX total reflection X-ray fluorescence (TXRF) spectrometer was studied for determination As and trace metals in Haveri Au-Cu sulphide mine tailings leached with aqua regia water affected by acid drainage. Results 12 16 samples were compared accredited methods, inductively coupled plasma-atomic emission spectrometry (ICP-AES) plasma-mass (ICP-MS).
