Characterization and suitability of Ijero (Ekiti State, Nigeria) mica for paint production

This project studies how to process, characterize, and test muscovite‑mica from Ijero in Ekiti State, Nigeria, for use in paint. Raw mica is first broken down with a jaw crusher, then ground in a hammer mill, and finally sieved with precision screens to get a controlled particle‑size range. The material’s chemistry is checked with X‑ray fluorescence (XRF) to find its elemental makeup. Its surface shape and element distribution are examined with scanning electron microscopy (SEM) together with energy‑dispersive X‑ray spectroscopy (EDS). The tests show an average particle size of about 12.7 µm. The mineral is mainly muscovite, with only trace amounts of biotite. Key elements—silicon, aluminum, potassium, magnesium, iron, and

titanium—are all present, confirming that the processed mica can work as a functional extender pigment in paint manufacturing. The work also outlines how to evaluate local mineral resources, set up experimental steps for mineral processing, and interpret spectroscopic data to prove industrial suitability.
