Abstract. The lead-zinc deposits of Nigeria occur, with few exceptions, in the main belt of lower Cretaceous formations in the Benue and Niger river region. They constitute mineralized fracture fillings in folded and faulted Aptian to Turonian strata, are closely associated with and probably genetically related to dioritic intrusions emplaced ...

Evaluation of tailings from processing plants is always an important issue. Lead-Zinc ore tailings containing 3.12% Zn, 3.43% Pb, 0.71 g/t Au and 74 g/t Ag was subject to this study.

Since 1996, hydrogeochemical surveys have been carried out in the abandoned Montevecchio Pb-Zn mining district (Sardinia, Italy), where mine drainages discharge directly into the local streams, to investigate variations in the aqueous occurrence of contaminants. Natural attenuation in dissolved contaminants occurs downstream of …

Lead (Pb) and Zinc (Zn) are heavy metals commonly found at the same work places [1]. Both these metals have unique physical and chemical properties that make them suitable for great variety of applications. Pb has become common environmental and occupational contaminant widely distributed in the world.

Lead solubility according to the EDTA test decreased with phosphate dose for both materials tested. Lead uptake by plant leaves and roots from the soil sample decreased with the phosphate addition, while Cd uptake remained almost constant. An adverse effect on plant growth and Zn uptake was observed for calcium oxyphosphate …
