Abstract

This paper presents a detailed study of Galena samples' chemical and mineralogical properties collected from the Duguri area in Bauchi State, Nigeria. The sample for the research was sourced from Duguri town, Bauchi State, Nigeria. The sourced sample underwent comminution, homogenization, and sampling using the Coning and Quartering method followed by the Jones Riffle sampling method. Chemical analysis results of the crude ore sample showed the presence of Lead oxide (PbO) at an assay of 36.827 %, with Silica as the major gangue mineral present at 45.823 %. The other compounds present in the ore are ZnO (9.656 %), Fe2O3 (8.290 %), Al2O3 (3.409 %), TiO2 (1.072 %), WO3 (0.312 %), and AgO (0.001 %). Mineralogical Characterisation using XRD revealed the phases present in the ore as; Galena (47 %), Cerussite (19.0 %), Quartz (18.8 %), and Gratonite (15 %), hence confirming that the soured ore was Galena (PbS). SEM/EDS results showed the morphology of the sourced sample, containing Lead with other impurities in their quartz form within the ore matrix, with the presence of other elemental constituents (Si, C, and O).
