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.

Enhanced Bauxite Recovery Using a Flotation Column

According to the results of the flotation experiments , flotation performance of the bauxite ore was improved with an increase in the number of packing layers. CFD was capable of simulating flows and predicting flotation process by providing visualized data [21,22,23]. Therefore, CFD was deployed to numerically analyze the collection zone of the flotation column with an air-water two

Separation of silica from bauxite via froth flotation ...

2009-3-1  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”.
