Potential technologies — strategy one — reduce reactive silica input2.1. Screening/washing2.1.1. PrincipleScreening and washing is effective in reducing silica in the bauxite feed material if the silica is preferentially concentrated in the smaller particle size fractions or fines. Bauxite is “wet screened” on inclined or vibrating screens.
