 · A study was performed to characterize the Ishiagu leadzinc deposit prior to beneficiation. The study included the use of XRD, SEM and both reflected and transmittedlight microscopy. The results showed that the ore consists mainly of galena (PbS), sphalerite (ZnS) and quartz (chert), with pyrite, siderite and chalcopyrite occurring as trace minerals. The textural relationships among the ...

In Nigeria, even though mercury remains a significant longerterm threat to the environment and to human health, the unprecedented acute health effects to date have come from lead. To retrieve the leadrich gold ore, workers in Nigeria are lowered on ropes into holes about 45 meters deep where they mine the ore using rock hammers.

The Ishiagu leadzinc deposits of southeastern Nigeria are associated with folded shales of the Asu River Group. The PbZn mineralization is restricted to a series of closely spaced, steeply dipping subparallel fractures which trend NWSE and typically form enechelon patterns.

Nigeria is the largest oil and gas producer in Africa. Crude oil from the Niger delta basin comes in two types: light, and comparatively heavy – the lighter around 36 gravity and the heavier, 20–25 gravity. Both types are paraffinic and low in sulfur. Nigeria's economy and budget has been largely supported from income and revenues generated from the petroleum industry since the 1960.

These untapped deposits is said to contain over 50 million tonnes. The coal exists as lignites, subbituminous coal and bituminous coal. Columbite. Columbite is another untapped mineral resource in Nigeria. It is found in states like Plateau, Kano, Kaduna, Bauchi, Kogi and Nassarawa states. Columbite is an ore of niobium.

Background: The belief that Chinese teas are of immense health benefits by many Nigerians has led to high consumption rate. Objectives: This study has determined lead and polycyclic aromatic hydrocarbons (PAHs) levels of Chinese teas popularly consumed in Nigeria and to estimate the potential health risks. Material and methods: Twenty brands of Chinese teas commonly consumed in Nigeria ...

Galena is found in Nigeria, West Africa in large deposits mainly in Ishiagu, Ebonyi State, with an estimated reserve of 15 million tonnes, other states with these deposits include; Taraba, Kwara, Ogun, Kogi, Ekiti and Nasarawa.. Physical properties of Galena Galena is the principal source of lead (II) sulphide with a melting point of 1,114 °C and a boiling point of 1,281 °C.

A detailed mineralogical and elemental characterization of a lead (Pb) ore deposit from Ishiagu, Ebonyi State, Nigeria was carried out with XRD, SEMEDX, and ICPOES based mappingtechniques. The results show that the most dominant and valuable metal is lead (Pb = %, mass fraction). The main mineral is galena.
