Obtaining accurate data is a challenge. Time lags, data gaps, and lack of disaggregation are common problems. Often proxies for common examples of hidden hunger are imperfect. For example, anemia is used as a proxy for iron deficiency, although only half of all anemia is caused by iron deficiency (de Benoist et al. 2008).

Mining is the extraction or removal of minerals and metals from the earth. The Nigerian Coal Corporation is a parastatal corporation that was formed in 1950 and held a monopoly on the mining, processing, and sales of coal, lignite, and coke products until 1999.. Coal was first discovered in Enugu in 1909 at the Udi Ridge in Enugu. It was found by Albert Kitson, a British mine engineer.

1. Introduction. A mineral can be defined as a naturally occurring element or chemical compound, crystalline in nature, formed as a result of geological processes (Nickel, 1995).They occur as aggregates, commonly referred to as rocks (Oshin, 2003).Minerals can be classified into the following groups based on their composition and uses: metallic minerals (e.g. Iron and Gold.); industrial ...

A number of Nigerian iron ore deposits have been upgraded to the specifications of concentrates for the blast furnace and the direct reduction iron- and steel-making plants. Depending on the mineralogy of the ore deposits, the techniques of oil agglomeration, magnetizing reduction, washing and scrubbing, gravity concentration, and reverse froth flotation have been utilized. A mode of ...

Challenges to be overcome to achieve successful processing of these ores are the complex ore mineralogy, the low content of amenable materials, the fine or extremely fine dissemination of the minerals and variable metal grades. Two years in to the project several important tasks have been fulfilled and critical milestones met. The first task for...

Deforestation is a serious problem in Nigeria, which currently has one of the highest rates of forest loss (3.3 Percent) in the world. Since 1990, the country has lost some 1 million hectares or 35.7 percent of its forest covers . Worse Nigeria's most biodiverse ecosystems—its old-growth forests is that are disappearing at an even faster rate.
