39 which could be used for low A/S bauxite that is found in large reserves in China, 40 became an important technical method for the sustainable development of the 41 aluminum industry in China(3, 4) 42 A large amount of water is needed for the bauxite desilication process, and a large 43 quantity of water can be saved by water recycling through flocculation and the rapid
1. Used for Bauxite flotation-In the process of bauxite flotation and separation of silicon, such as, aluminum silicon ore and arsenic containing silicon ore. 2. Resistance for acid and alkali,the removal rate of silicon can be achieved under neutral condition, and the removal rate is above 95%. 3.
Bauxite tailings (BTs) generated during the flotation-Bayer process, which is used in China to produce alumina from medium- and low-grade bauxite ore, are a type of waste product. The flotation method is a common technique used to separate the valuable minerals from ores containing Al, Cu, Pb, and Zn.

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].
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 ...
In this investigation, the fine-grained bauxite ore flotation was conducted in a plate-packed flotation column. This paper evaluated the effects of packing-plates on recovering fine bauxite particles and revealed the fundamental mechanisms. Bubble coalescence and break-up behaviors in the packed and unpacked flotation columns were characterized by combining Computational Fluid Dynamics (CFD ...

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 ...
The depressing function of bacteria of LKD on diaspore and kaolinite is studied through flotation experiments, mineral ζ-electric potential and infrared spectroscopy analysis. Waste beer has better selective and depressing effects on diaspore in the range pH 2-10 than starch-like substances do. The analysis of mineral ζ-electric potential and infrared spectra shows that the bacteria of LKD ...
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.
Flocculation and sedimentation of fine bauxite from flotation tailing pulp were studied using different flocculants to investigate the possibility of its application.
Flotation usually adopts the process of one roughing, two cleaning and two scavenging. Several application of bauxite. 1. Crushing, sceening, calcination and make high aluminum material, which is used in refractory materials such as firebricks; 2.
Aluminum-silicates such as pyrophyllite, illite, kaolinite and chlorite are impurity minerals in diasporic-bauxite, it being necessary to remove these silicate minerals to improve the mass ratio of Al 2 O 3 /SiO 2 of diasporic-bauxite for the Bayer process. A new quaternary ammonium salt (DTAL) has been shown to be efficient in the flotation of these silicates.
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 ...
