Morphological and mineralogical characterization of beneficiated Philippine diatomaceous earth

Diatomaceous earth is a naturally occurring non-metallic material generally composed of silica (SiO₂), alumina (Al₂O₃). It possesses a variety of cylindrical pores originating from fossilized diatom cells positioned in different random orientations. In this study, presented as a poster at the SelectScience^® Virtual Analytical Science Summit 2022, the morphology and mineralogy of beneficiation diatomaceous earth were evaluated.
