Evaluating the Behavior of Bauxite Tailings Dewatering in Decanter …
Depending on the ore quality, a washing process can be conducted with the bauxite, which basically consists of scrubbing the ore and screening in order to increase the available alumina grade, i.e., the alumina extractable using the Bayer Process, and reduce the impurity content. Tailings are usually disposed of in a tailings dam in the form …

Separation of silica from bauxite via froth flotation
The chemical analysis presented in Table 1 shows a very high content of SiO 2 in the sample (39.0%). Quartz content is represented as insoluble silica (In SiO 2), and SiO 2 in kaolinite is the reactive silica (Re SiO 2).Available Alumina (AA) shows the alumina content in gibbsite, recoverable by the Bayer process: 24.7% in the head sample.
