AN ANALYSIS OF PROPERTIES OF KAOLIN DEPOSITS IN NIGERIA
The purpose of this project covers two deposits, the Kpankorogi and the Ijero-Ekiti kaolin deposits. Samples were collected from each of the deposits for oxide analyses, mineralogical analyses as well as the determination of the engineering and physical properties. The numbers of samples are limited due to cost constraint.

The most significant kaolin deposits were formed through intensive weathering of rock rich in feldspars (granite, arkoses, certain types of ortho-gneisses and misgmatites). Millions years ago, original material was decomposed by weathering, giving rise to kaolin and silica combined with higher or lower amounts of admixtures.(Bernard, el al; 1992).
