Production of Nanosilica from Iron Tailing and Characterization

Abstract:

Article Preview

Nanosilica was extracted from iron tailing by the chemical deposition method, involving pickling, filters washing, alkali dissolving of pickling dregs in high temperature, precipitating silica controlled by diluted acid and so on. The product has been studied by SEM, XRD, FT-IR, and thermal analysis techniques, etc. These study shows that the nanosilica is a kind of amorphous matter consists of hydrous silicon dioxide (97.076%) with small amount of sodium and aluminum trapped inside the Si–O network. The diameter of globular silica particles is 30-50 nm.
