  • Bauxite Beneficiation & Flotation Silica & Iron

    2021-7-4 · The most widely used chemical process of refining bauxite into alumina, the Bayer process, involves dissolving the Al2O3 out of the bauxite rock with caustic soda (NaOH) at elevated temperature and pressure. The Al2O3 fraction of the bauxite is dissolved into solution, to Cao Binfang et al. Metallurgy and materials,2017-9-18 · The bauxite flotation circuit is a long and complex separation process, con- sisting of the following flotation banks: roughing bank, rough-scavenging bank, clean-scavenging bank, clean- ing I bank and cleaning II bank. Each flotation bank is composed of dozens of flotation cells. This is done to en- sure both high concentrate grade and recovery.
