In this current investigation, bauxite washing was conducted in the laboratory. Bauxite washing is a physical process that causes the disintegration and deagglomeration of the clay matrix, and bauxite is liberated from the clay (mainly rich in silica). Subsequently, separation occurs with the assistance of wet screening at a predetermined cut size.

Sometimes washing and screening will target quartz only. Rousseaux et al. (2006) examined the use of drum washing (and subsequent cyclones) to remove quartz known to be in Pijiguaos bauxite in the size range 0.1–3.0 µm. Amer and Abdel-Aal (1996) separated ∼ 82% of quartz from an Egyptian bauxite by simply pulverising and …
