Abstract :

This work focused on the characterization and assessment of the economic potential of sand deposits in Anambra State. It was undertaken to determine the potential of the sand for use in glass and solar panel manufacture. Samples collected from quarries at Agu-Awka, Ishiagu, Nimo, Umuoru-Uga and River Awdaw channel at Amaokpala were texturally and chemically analyzed. Result of sand-size analysis of the samples revealed that 85.7-95% of the samples were retained within the 0.125-0.5 mm sieve meshes. This range of values falls within the sand-size threshold suitable for the manufacture of glass wares. Result of X-Ray Fluorescence spectroscopy showed that SiO2 percent ranged between 93.87 and 98.01, followed by Al2O3 (0.94-1.84), Fe2O3 (0.367-1.681), TiO2 (0.23-1.05), Cr2O3 (0.025-0.042), CuO (0.019-0.039), K2O (0.001-0.38). The very high concentration of silica shows that with very minor beneficiation, all the sample can be employed in the manufacture of glass and solar panels. These findings provide basis for investments in commercial silica sand and thus herald a new dawn of business opportunities in Anambra State.
