The major type of bauxite in China is low-grade diasporic bauxitewhich is mainly composed of diaspore and kaolinite. Separation of silicate minerals by flotation technology can meet the requirements of Bayer processbut Na K and Cl deriving from mineral dissolution and entrainment in flotation water will inevitably mix in the flotation slurrywhich will affect the .
The flotation properties of single minerals such as diasporekaolinite and pyrophllite in bauxites were investigated using RL as collector. The effects of regulators and unavoidable ions on flotation were studied. Based on the results of single minerals flotationthe separation experiments of mixed minerals and bauxite ore were carried out. The results of closed circuit test on the ore show

Oct 012014 Variability and floatation which are surface properties of aluminum silicate minerals and ease of reproduction of mudunlike flotation method has made desilication difficult as compared to other common methods of flotation. Thereforea new method of removing mud about disturbing factors of diasporas bauxite ore flotation has been studied 5.
Sodium hydrogen sulfide (NaHS) is commonly used as a copper depressant in the selective flotation of copper and molybdenum ores. Howeverthe process is facing health and safety issues because NaHS readily yields toxic hydrogen sulfide gas (H 2 S) under acidic conditions. In this studyNa 2 SO 3 was proposed as an alternative copper depressant. The effect of Na 2 SO 3 on the surface
Apr 192013 Bauxite resources are widely spread in the earth. Howeverthe effective utilization of this mineral is still under infant. The conventional collector for diaspore mineral is oleic acid. It has three main drawbacks which are highly insolublelarge dosages in bauxite flotationand low selectivitywhich hinder its application in industry. In this researchoctylic hydroxamic acid was
The title Ion Flotation was suf- ficiently mystifying to stimulate a wish to review this monograph. Unquestian- ablyDr. Sebba deserves credit far fovus- ing strention on the potential fundemental and practical utility of well-known intprfacial phenomena in liquid-liquid (and solid-liquid) interfaces in
Dec 172020 Conventional ion flotation is hydrodynamically constrained by coupling of the gas flux and liquid flux that report to the concentrate. This constraint has greatly limited the industrial application of ion flotationdespite its remarkable effectiveness in extracting ionic species down to very low concentrationsof order 1 ppm. Previous work demonstrated that these hydrodynamic constraints
The flotation chemistry between pyrite and isomeric xanthates (butyl xanthate and isobutyl xanthate) was investigated by means of adsorption experimentssurface tension testsand molecular dynamic simulations in this work. The flotation chemical results were confirmed and further interpreted by quantum chemical calculations. The experiment results demonstrated that the isobutyl xanthate
Bauxite deposits are spread worldwidemostly occurring in tropical or subtropical regions. Although proven reserves of bauxite are expected to last for many yearsthe quality of the reserves that can be economically accessed is declining. For refinerswho are in the business of processing bauxite to make aluminaand eventually aluminum metalthis is a challenge with both financial and
Howevera high-grade bauxite contains up to 60% Al2O3and many operating bauxite deposits are well below thisoccasionally as low as 30-40% Al2O3. Because the desired product is a high purity Al2O3the remaining oxides in the bauxite (Fe2O3SiO2TiO2Organic material) are separated from the Al2O3 and rejected as alumina refinery resides
Jul 122019 Insteadthe usual ore of aluminum is bauxite - which contains from 50 - 70% of aluminum oxide. A common example of this involves froth flotation. electrons are being added directly to the metal ions at the cathode (the negative electrode). The downside (particularly in the aluminum case) is the cost of the electricity. An advantage is

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-platesthe recovery of Al 2 O 3 increased by 2.11%and the grade of Al 2 O 3 increased by 1.85%. The fraction of 20 m mineral particles in

The effect of iron ions in backwater on the flotation of diaspore bauxite was investigated by ICP measurementmicro-flotation testszeta potential measurements and solution chemistry analyses. The concentration of iron ions in backwater was 1 10 5 molL measured by ICP. The micro-flotation results indicated that iron ions activated the flotation of diaspore at pH 4 and depressed the flotation of diaspore at pH 7while activated the flotation

Dec 012017 Fine liberation size makes it unavoidable to encounter slimes during processing of diasporic bauxite. Through flotation separationdiaspore can be disseminated in course particles among the aluminosilicates or the dominant presence of gangue particles traps fine diaspores in the slime (Yuhua et al.2011). Thereforereagent (collectors or depressants) interactions with diaspore can be
