2017-9-18  2.2 Influencing factors of the bauxite flotation process Bauxite flotation is a very compli-cated and non-linear process, and many direct or indirect parameters frequently exert influence on the production indi-cators (Zhao et al., 2010, CAO, et al., 2013, Sandro, 2012). However, fewer model parameters should be considered

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”.

2016-5-17  Methods for decreasing silicates content include the process of grinding and screening (Liu et al., 2011), flotation, and biological processing. Generally, the direct flotation process is the most practical and widely applicable method in the bauxite industry. In the direct process, alumina minerals of diaspore are subjected to froth flotation.

Fine Bauxite Recovery Using a Plate-Packed Flotation

2020-10-6  Dynamics (CFD) and Population Balance Model (PBM) techniques. Flotation experiments showed that packing-plates in the collection zone of a column can improve bauxite flotation performance and increase the smaller bauxite particles recovery. Using packing-plates, the recovery of Al2O3 increased by 2.11%, and the grade of Al2O3 increased by 1.85

Characteristics of bio-desilication and bio-flotation of

2017-11-10  Adsorption process of BM-4 on bauxite and kaolinite were studied, respectively. The adsorption of BM-4 on kaolinite was the electrostatic adsorption. While the adsorption of BM-4 on bauxite was the Langmuir isotherm adsorption process. (3) The flotation recovery of kaolinite was improved from 50.1% to 65.3%–77.3% due to the adsorption of BM-4.

Flotation techniques for separation of diaspore from

2010-3-22  Bayer process[6] has been used in industry. The sintering process is extremely energy-consumed and environmentally unfriendly, incurring a high alumina production cost. Therefore, it is highly desirable to increase the A/S of the bauxite ores by a low cost physical separation process. Froth flotation is one of the most widely used

Ionic Effect of NaCl and KCl on the Flotation of

2020-1-28  Abstract. The major type of bauxite in China is low-grade diasporic bauxite, which is mainly composed of diaspore and kaolinite. Separation of silicate minerals by flotation technology can meet the requirements of Bayer process, but Na +, K + and Cl − deriving from mineral dissolution and entrainment in flotation water will inevitably mix in the flotation slurry, which will affect the
