Risks associated with the mining of PbZn minerals in some

The environmental effects of the mining of leadzinc mineralization in Enyigba area, Southern Benue trough were examined. The samples used for this study were obtained from abandoned mine sites, mine tailings, streams, handdug wells, mine pond and borehole. Collected samples were subjected to Xray fluorescence, Xray diffraction analyses, atomic absorption spectrometry and permeability tests.
