A brief look at the geology of Nigeria is important to give an idea of the geological composition of the country in terms of the ore bearing rock groupings, while the review of Pb-Zn mineralization is intended to give credence to findings in previous studies that the Benue Trough houses some of the complex sulphide minerals including the lead ...

Exploration of Lead-Zinc (Pb-Zn) Mineralization Using Very ...

Trough, Nigeria was carried out to determine the Pb-Zn mineralization in the sedimentary bedrock. The conductivity contrast between the conductive mineralized veins and the host rock as generated by induction mechanism was used to delineate the potential zones of Pb-Zn mineralization. Results of high in-phase and quadrature readings due

This study determined the heavy metals concentration in arable soils and associated food crops around the Pb–Zn mines in Enyigba, Nigeria, and metal transfer factors were calculated.

Mineralogical and Geochemical Characterization of Gold ...

Most of these dispersed elements (e.g., Cu, Ag, Zn, Cd, As, Bi, Pb, Sb, Hg, W, Mo. and Se) are useful indicators or pathfinders for the presence of gold [6, 7]. Analyses of samples taken enable the observation of patterns and concentrations in the distribution of metals in the soil which would potentially indicate enriched rock underneath.

Sources and behavior of trace elements in groundwater in ...

The groundwater is tapped from the Miocene and the fractured basement rock aquifers. The mean concentrations of trace elements exceed the guideline values of all organizations, except in some wells for Zn, Cu, and Co. Cationic trace elements declined in the order of Mn > Fe > Zn > Al > V > Ni > Rb > Sr > U > Cu > Cr > Co > Cd > Pb > Th > Sb > Hg.

Lead Isotopic Composition and Lead Source in the ...

Then, in the light of the Pb isotope composition of metamorphic rock samples from the Proterozoic basement exposed in the Dulong ore field, we have determined the Pb isotope composition and obtained the isotope ratios as: 206 Pb/ 204 Pb = 18.434‐19.119, 207 Pb/ 204 Pb = 15.644‐15.693, and 208 Pb/ 204 Pb = 38.514‐38.832.

Impact of the Pb and Zn ore mining industry on the ...

The development of mining and metallurgic industries of Pb and Zn ores in the Biała Przemsza catchment area has had a strong influence on the condition of the surface water and bottom sediments. In the following study, total contents of metals and metalloids were researched in the water and bottom sediment samples from the Biała Przemsza River.

A Review of the Health Implications of Heavy Metals in ...

Heavy metals such as Zn, Pb, Fe, and Cu are abundant in the environment and contribute largely to the sustainability and equilibrium of ecosystem processes. However, because of their bioaccumulation, nondegradability, and the excessive amounts in which they exist, these metals contaminate the food chain and subsequently become a source of toxicity to human beings and the entire ecological ...

Kangerluarsuk - Bluejay Mining

An area with a recent history of mining: the project is located in a proven Zn-Pb district, only 10 km south of the former Black Angel (or Maamorilik) mine that is regarded as Greenland's most profitable mine to date, producing 11 million tonnes at 12.6% Zn, 4.1 % Pb and 29 g/t Ag from 1973 to 1990 during operation by Comico and Boliden.
