Mar 01, 2009  Bauxite flotation practice Worldwide, the industrial practice for bauxite consists in feeding the ROM ore directly to the alumina production plant. Shaffer (1985) , in his contribution to SME Mineral Processing Handbook chapter on alumina, literally writes that “the intrincate milling and mineral dressing techniques common in the base metal industry are not used on bauxite”.

However, a high-grade bauxite contains up to 60% Al2O3, and many operating bauxite deposits are well below this, occasionally as low as 30-40% Al2O3. Because the desired product is a high purity Al2O3, the remaining oxides in the bauxite (Fe2O3, SiO2, TiO2, Organic material) are separated from the Al2O3 and rejected as alumina refinery resides ...

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.

The bauxite residue sinks to the bottom of the settling tanks, then is transferred to the washing tanks, where it undergoes a series of washing stages to recover the caustic soda (which is reused in the digestion process). Further separation of the pregnant liquor from the bauxite residue is performed utilising a series of security filters.
