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 ...
The present invention relates to a bauxite crude-fine grading flotation desilicification method. In the present invention, ground raw ore slurry is graded into a coarse sand part and a fine sand part according to certain granularity; fine clay is treated by direct flotation technology, and the coarse sand is treated by reverse flotation technology; consequently, the optimization of the ...
The present invention relates to a bauxite combined floatation desilicification method. It is characterized by that said method adopts the following measures: designing main process of bauxite floatation separation and desilicification into reverse floatation to obtain bauxite tank bottom headings, combining the previously deslimed overflowed product produced in reverse floatation main process ...

The effect of Al3+ in backwater on the flotation of diaspore bauxite was investigated by micro-flotation tests and the underlying mechanisms were investigated by inductively coupled plasma (ICP) measurement, zeta potential measurements, solution chemistry analyses, and synchrotron near edge X-ray absorption fine structure (NEXAFS) analyses. The ICP measurement results show the …
1. Introduction. Chinese bauxite ores have required more elaborated beneficiation processes than the Brazilian bauxite ores. This fact is a consequence of the low alumina/silica (Al/Si) mass ratio in currently mined Chinese ores (Xu et al., 2004 XU, Z., PLITT, V., LIU, Q.Recent advances in reserve flotation of diasporic ores - A Chinese experience.
An innovative self-designed medium was packed in a bench-scale flotation column to study its influence on the flotation recovery of bauxite. Computational fluid dynamics (CFD) simulation was conducted to reveal the impact of the packing medium on the turbulent characteristics of collection zone in the column. Simulation results show that multilayer packing of the medium divides the collection ...
Flocculation and sedimentation of fine bauxite from flotation tailing pulp were studied using different flocculants to investigate the possibility of its application.
ABSTRACT Bauxite ore is the primary mineral resource for the production of aluminum metal and includes gibbsite [Al(OH) 3], diaspore [α-AlO(OH)] and boehmite [γ-AlO(OH)]. Gangue minerals generally include iron oxides (Hematite [Fe 2O 3], Goethite [FeO(OH)]), silicates (quartz [SiO 2]), kaolinite [Al 2Si 2O 5(OH) 4] and others such as rutile/anatase [TiO 2].
Selective flocculation is a new method to solve the problem of China's bauxite de-silication besides flotation and reverse flotation. The method of selective flocculation of bauxite using hydrolyzed polyacrylamide as flocculant was experimented and evaluated. The results of diaspore and kaolinite single mineral settling tests show that the difference between settlement yield …
The bauxite flotation plants in China, most of which were built and put into production after 2009, retained good flotation indexes by discharging the backwater out of the recycling system and replacing it with fresh water. There are no reports on research and industrial applications of backwater treatment of bauxite flotation.
Two flotation schemes were employed to produce high-grade corundum concentrates. The concentrates resulting from each scheme exceeded the national stockpile specifications for calcined bauxite. Flotation of the corundum using petroleum sulfonate in an acid circuit resulted in …
The reports of Gandrud and DeVaneyl and Clemmer, Clemmons, and Stacy show the possibilities of flotation as a means of beneficiating bauxite. Their work has also developed reagent combinations that are satisfactory for flotation of gibbsite. [11] The tailings of the beneficiation plant described in chapter 4.3 (Itamarita de Minas) still contain ...
