    Physico-chemical appraisal of Agwada chalcopyrite ore, Nasarawa State
    (DEPARTMENT OF GEOLOGY AND MINING FACULTY OF APPLY AND NATURAL SCIENCES NASARAWA STATE UNIVERSITY, KEFFI, 2014-11-24) Jatau, B.S.; Akindele, U. M.; Aye, A.E.
    The physical, petrological and chemical analysis of chalcopyrite ore from Agwada, Kokona Local Government Area of Nasarawa State, Nigeria, was carried out using petrological microscope and XRF spectrophotometer. The physical analysis revealed the following: hardness 3.5, specific gravity 3.8, metallic lustre, light brown greenish colour with reddish brown streak, has an imperfect cleavage and brittle. The petrological analysis also showed that the associated minerals are Biotite, Plagioclase, Muscovite, Quartz, Orthoclase and Sanidine. The chemical analysis results obtained on average is as follows: 5.55% Al203, 19.49% SiOz, 10.63% CaO, 32.91% Fe203, 0-64% MnO, 4.62% CuO, 1.88% ZnO, 4.57% KjO and 16.82% S03. The petrological and chemical analyses of the sample indicate that the chalcopyrite ore is viable for exploitation.
