LEAD (Pb) MINING IN EBONYI STATE, NIGERIA:

2018-5-2  Ebonyi State is one of the States in Nigeria that is endowed with solid minerals including lead ores. Unregulated mining in Ebonyi State started with the mining of lead-zinc (Pb-Zn) ore in 1925 (2) and since then Pb mining has progressed tremendously because of its high demand. Lead has a low melting point, is easily moulded and shaped, and can ...

Assessment of Water Pollution Status in the Mining Area

2018-1-28  Ebonyi River and the two Ameka mine sites recoded the lowest pH of 4.06, 1.15 and 4.88 respectively (table I). This high acidity cannot be dissociated from the lead/zinc mining activities in the area. Contrarily, the Enyigba salt lake recorded a pH of 9.87. This high pH is associated to the high concentration of salt in the lake.
