Phosphate rock is essential and basic raw material for fertilizer and chemical based industries. In this
research work, characterization of Ghari Habibullah (GHU) phosphate rock samples, were carried out. Aim of the study
is to determine mineralogy of the ore deposits by using thin sections, X-ray Diffraction (XRD) and Scanning Electron
Microscope (SEM) techniques. Elemental composition was determined by X-ray Fluorescence (XRF), assay of ore
minerals and various gangue minerals were determined by chemical analysis. Mineralogical study results showed that
the major gangue minerals present with ore mineral (apatite) are silica, hematite and calcite. The SEM analysis revealed
that apatite (fluorapatite) was sandwiched between silica and calcite. X-ray Fluorescence indicated apatite grade is
22.85% which is below the marketable cutoff grade and main gangues are quartz 40% and hematite grade greater >2%
is more than the required limit of fertilizer. The iron content should be kept low in the fertilizers, reduces the solubility
efficiency of water, which have a diverse effect on the production of Single Super Phosphate.
