Barite in the approximately 513 Ma Lemarchant volcanogenic massive sulphide (VMS) deposit, Newfoundland, consists of granular and bladed barite intimately associated with mineralization. Regardless of type, the composition of barite is homogeneous at bulk rock and mineral scale containing predominantly Ba, S, and Sr, with minor Ca and Na.
Mehdiabad is the world's largest Mississippi Valley-type (MVT) Zn-Pb deposit (394 million tonnes [Mt] of metal ore at 4.2% Zn, 1.6% Pb) and contains significant barite resources (>40 Mt). Such large accumulations of barite are not …

Plants with a high diversity index were taken for analysis from both aquatic and terrestrial habitats. Scoparia dulcis L. seems to specialize in metal accumulation, possibly for protective purposes. ... Atmospheric deposition of …
The heavy metals' concentration at barite mining sites for Pb was higher than those reported for cosmetics (Pb at 0.02885 mg kg−1 d−1 ) [18] and is within the range reported for Pb, Zn, Cu, and Fe on artisanal gold mining sites [18,35]. 3.4.2.
The Zn, Cu, Cd, and Pb concentrations accumulated in plants was high, in the same way as other aquatic species suggested for heavy metal removal (Miretzky et al., 2004, Gardea-Torresday et al., 2005).The investigation found that all plant parts took up all four metals (Table 1).This corroborates earlier findings that Zn, Cu, Cd, and Pb are directly taken up by both the …
Introduction BARITE is commonly associated with Mississippi Valley-type (MVT) Zn-Pb mineralization and has been mined in many such environments, including the Appalachians (Kesler, 1996), in the Sardinia province of Italy (Boni et al., 1996), and in the Silvermines deposit of Central Irish Midlands (Andrew, 1995).
The second mineralization stage is partly superimposed on the first and consists of zoned east-west-trending Cu-Ag-(Au-Zn-Pb) enargite-pyrite veins hosted in the diatreme breccia in the western part of the deposit and well-zoned Zn-Pb-(Bi-Ag-Cu) carbonate-replacement orebodies; in both cases, sphalerite is Fe poor and the inner parts of the ...
The Magnet Cove Mine, located near Walton in Hants County, Nova Scotia, produced a total of 4 Mt barite and 0.36 Mt of Cu-Pb-Zn-Ag sulphide ore between 1941 and 1978. Currently, primary dispersion of heavy metals from ... the barite tailings from the sink-float plant, and the sulphide tailings from the mill-concentrator. ...
Environmental Geochemistry and Health, 2019. Urban soils of 32 Indian cities were collected from literature-based data for the period of 2001-2019 to measure the contamination levels of six heavy metals including arsenic (As), chromium (Cr), copper (Cu), zinc (Zn), nickel (Ni), and lead (Pb) and also evaluated the potential human health risk for adults and children.

About Pb-Cu. Lead and zinc are extremely close in nature, especially in primary deposits, and often coexist. Most of the lead-zinc minerals are sulfides and sulfates, and galena and sphalerite are the primary Pb-Zn ores. Non-sulfide: It is formed due to hypogene and supergene weathering. Mostly oxide ores like zincite, and cerussite may fall under this category.
