Abstract
In this study the sand deposits from River Niger in Anambra State, South Eastern Nigeria, were characterized for its potential utilization as industrial raw materials for ceramics and enamel wares. Physical, chemical and mineralogical characteristics of the sand sample (A) were determined. X-ray diffraction (XRD) was used in the mineralogical characterization. Results obtained were analyzed using Bragg-Wolf equation and International Centre for Diffraction Data software. The results show that the sample contain the phyllosilicate minerals of mica group and identified as shirozulite (KMn3 [Si3Al]O10[OH]2) a new manganese dominant of monoclinic arrangement. The physico-chemical analysis of the deposits corroborates the XRD results. The results concluded that the samples could be utilized as industrial raw materials for ceramic and enamel wares.
