Mineralogical characterization of Ishiagu (Nigeria) complex sulphide ore

Electrochemical, surface analytical, and spectroscopic study of passive film and pits formation on food grade ferritic stainless steel AISI‐430 in aqueous acetic acid containing chloride ions

“…Several points are worth considering while interpreting the XRD data. For example, the XRD can be very accurate in quantifying the major structures in a mixture, but it is not very efficient in detecting the constituents present in minor or trace amounts (≤2%) …”

“…The continuous dissolution of iron atoms leads to an increase in the pit dimension as well as its depth. The reactions taking place in the anodic region of the potentiodynamic polarization process are listed below (14)(15)(16)(17).…”

Narrow and Broad Beam Attenuation of Diagnostic X Ray Beam Across Lead Sample Found in Ebonyi State, South East Nigeria

“…It is exclusively fissure filling and distinctively patterned in the NW-SE fractures and gangue minerals [6] . [3] .…”

“…Nigeria's most important lead-zinc deposit is the Abakaliki field which is made up of four lodes: Ishiagu, Enyigba, Ameki and Ameri in the lower Benue trough [2] . A large deposit of over 20 million tons of complex sulphide minerals is available in Nigeria especially in Ishiagu, Ebonyi state [3] . It is estimated that Nigeria has over ten million tons of lead ore deposit predominantly found in Zamfara, Niger and Ebonyi states [4] .…”

“…Locally mined lead which could be used for wall designs is at varying stages of characterization. Olubambi [3] did a mineralogical characterization of Ishiagu, Ebonyi state, Nigeria's complex sulphide ore where their study provided relevant mineralogical information on which the processing of the ore could be easily achieved. Onyedika [5] made a detailed mineralogical and elemental characterization of this deposit using XRD, SEM-EDX and ICP -DES based mapping techniques where their results show that the most dominant and valuable metal is lead.…”
