Abstract
This study considered the suitability of Adogo feldspar deposit in Kogi State,
Nigeria for glass and ceramic production. The feldspar's sample was
characterised through analysis of its physical, chemical and mineralogical
properties. The results of the physical analysis showed that the mineral has a
bulk density of 1.3551 g/cm3 and tapped density of 1.5209 g/cm3, which was
used to determine the compressibility index and Hausner ratio. The index
shows that the powdered mineral has a good flow character. The result also
revealed that the mineral has a very low percentage of moisture content
(1.75%) and clay content of 2.9%. Meanwhile, the chemical analysis showed
that the feldspar mineral has dominant elements of Silicon (70%) and
Aluminium (20%), with 73% and 23% oxides of silicon and aluminium
respectively, negligible values of other elements and oxides in the feldspar.
The mineralogical analysis revealed that the feldspar deposit was of low
grade soda feldspar, while the phases present showed that the mineral was a
low-grade feldspar Albite Feldspar. Though, the physical and chemical
properties of the feldspar revealed the potential of the feldspar as a suitable
raw material in ceramics and glass industry but further beneficiation was
needed to meet suitability for the production of ceramic and glass.
