CHARACTERISTICSOF BAUXITE/ALUMINA/ALUMINUM A. Introduction 1. Bauxite, which consistsof oxide type ores containinghydrated alumina is mainly used for the production of aluminum. In addition, minor amounts of bauxite and alumina are consumed in the refractory, abrasive and chemical industries. 1/ Aluminum is obtained from two basic sources: (i) bauxiteores which dre refinedinto aluminaand then processedinto aluminum and (ii) aluminumfrom scrap.2/ B. Definitionof Products 2. The principaltypes of bauxiteare the trihydrate,gibbsite 'A103.3H20) and the monohydrates,boehmite and diaspore(A1 203.H20). Mono- nydratesare commonlyfound in Europeand NorthernAsia. In other parts of the world,bauxite is foundas gibbsite,but in some cases containingas much * as 20 percentboebmite. Trihydratebauxite is preferreddue to its higher solubilityin causticsolutions and the lowerpressures and temperatures requiredfor the refiningof alumina.3/ The most objectionableimpurities associatedwith bauxiteare silicatesand iron oxide. Bauxitewith a low iron contentmay be used in the chemicalindustry. Calcinedbauxite, prepared by heatingbauxite at high temperatureis used by the refractoriesindustry and to make intermediateabrasive products. 3. Alumina,is aluminumoxide (A1203 ) used for the productionof aluminumand in lesseramounts to producecalcined alumina for the manufacture of fused aluminaabrasives and high temperaturerefractories and activated aluminafor chemicalprocesses. 1/ In the U.S., about 12 percentof the aluminumconsumed in 1975 was used as bauxiteor aluminain nonmetalapplications. See Stamperand Kurtz. * 2/ In the U.S.S.R.,alumina is also extractedfrom nephelineand alunite. .3/ Stamper and Kurtz. February1981 I-2 4. Aluminumscrap is classifiedinto new and old scrap. New Scrap is gereratedin the manufactureof primaryaluminum and of aluminumproducts. It may be recycledby the same companythat generatesit or purchasedby other companies. Old scrap comes from discarded,used and worn out products such as aluminumengines or body parts,used aluminumcans and utensilsand old wire and cable.1/ 5. Aluminummetal has relativelylow densitv,high electricaland thermalconductivity, good resistanceto corrosionand may be alloyedand treatedto yield a high strergth-to-weightratio. 2/ Aluminumis available commerciallyas ingotswith a minimumcontent of 99.5 percentaluminum. Higherprices are paid for purer grades. 6. Ingots,molten aluminum and aluminumscrap with alloyingmaterials are transformedinto mill products,such as bars, rods and wire; plates, sheetsand strip;tubes rnd pipes;and other products. C. Uses 7. Most of the bauxiteis used for the productionof alumina. The remainderis used as bauxiteby the abrasive,refractory and chemicalindus- tries;to producealuminum sulfate and other chemicalsfor water treatment and for the paper industry;and for cements,catalysts and fluxes. 8. Alumina is mainly used to produce aluminum. Other uses are as calcined alumina in the abrasive, refractory and glass industries; as alumina hydratesto producealuminum chemicals and fire retardants; in tubular form for ceramicsand refractories,and as activatedalumina used to dehydrate liquidsand gases in the chemicaland petroleumindustries. 9. Consumptionof aluminummetal by end uses is shown in Table I.2. The transportationindustry accounts for about one fourthof metal consumption, 1/ Ibid. 2/ Stamperand Kurtz.

In this way, a 19 hazardous waste from the tertiary aluminium industry was studied for its use as a raw 20 material in the synthesis of an added value product, boehmite. This waste is classified as 21 a hazardous residue, principally because in the presence of water or humidity, it releases 22 toxic gases such as hydrogen, ammonia, methane and hydrogen sulphide. The low 23 temperature hydrothermal method developed permits the recovery of 90% of the 24 aluminium content in the residue in the form of a high purity (96%) AlOOH (boehmite). 25 The method of synthesis consists of an initial HCl digestion followed by a gel 26 precipitation. In the first stage a 10% HCl solution is used to yield a 12.63 g.l-1 Al3+ 27 solution.

  • The Solubility of Aluminium in Melts Containing Aluminium Halides
    THE SOLUBILITY OF ALUMINIUM IN MELTS CONTAINING ALUMINIUM HALIDES A Thesis presented for the degree of Doctor of Philosophy in the University of London by John Dyson Usher London, May 1965 ABSTRACT A technique for measuring the solubility of aluminium in NaF-A1F3 and Nall-A1F3+5%A1203 melts has been developed using a refractory titanium boride- carbide crucible and a gas volumetric method of analysis. Experiments were conducted at 10209 1100 and 1180°C; in both systems no change in solubility limit was detected over the experimental composition range of 25.6 - 36.6 and 25.8 - 31.9 mol % AlF3 respectively. The figures in the pure fluoride are 0.022 0.041 and 0.072 wt %; in the alumina melts 0.073, 0.121 and 0.169 wt %. Solution mechanisms have been suggested which account for the observed behaviour, and an attempt has been made to interpret the current inefficiency process in the reduction cell in terms of the results.

  • Cryolithionite and Li in the Cryolite Deposit Ivigtut, South Greenland
    Cryolithionite and Li in the Cryolite Deposit Ivigtut, South Greenlan d By HANS PAULY Matematisk-fysiske Meddelelser 42 : 1 Det Kongelige Danske Videnskabernes Selskab The Royal Danish Academy of Sciences and Letter s Commissioner : Munksgaard • Copenhagen 1986 Abstract Cryolithionite always occurred as single crystals in cryolite : idiomorphic, subidiomorphic and, rarely , anhedral . It was found in siderite- cryolite ; in a variety of this type : black cryolite with red-brown Th - containing fluorite, siderite etc . (BCrbF) ; in pure, white cryolite ; in cryolite veining the wall rocks . I t belongs to the period in which siderite- cryolite formed . Analyses of 268 cryolite samples gave 92 ppm Li (min. 19, rnax . 224 ppm) . Cryolite from samples with cryolithionite : 81 ppm, cryolite from BCrbF with no cryolithionite : 185 ppm . Cryolithionite seems to have formed by exsolution from cryolite with 155 ppm Li or more . The high con- traction of cryolite on cooling (1 vol% pr. 100°C) may have given rise to low-pressure regions within the cryolite where cryolithionite (d= 2 .77) replaced cryolite (d- 2 .97) after formation of the complicated twin structures in the cryolite - at or below 450°C . The compound Na 2LiAIF 6 (d=3 .02) is not present in th e deposit.

When, by X-ray diffraction, the microcrystals present a basal reflexion (d[020]) of 0.611 nm, the crystalline structure is referred to as “well-crystallised” boehmite. Natural and synthetic crystals of well-crystallised boehmite can have a plate-like shape with either a rhombic or hexagonal profile. Synthetic crystals can also be lath-like or ellipsoid in shape. The purpose of this paper is to present a method of hydrothermal synthesis using a single temperature (200 °C) for preparing plate-like crystals of well- crystallised boehmite with ellipsoid, rhombic, hexagonal, and lath-like profiles by using different precursors. Our observations suggest that all of these shapes are stages of growth of the microcrystals of well-crystallised boehmite along the c-axis direction of the rhombic crystals. Keywords: aluminium hydroxide, boehmite, pseudoboehmite, fibrillar pseudoboehmite 1.

Ltd. of CHALCO, Zhengzhou 450041, China; [email protected] * Correspondence: [email protected] Abstract: Lithium is one of the secondary mineral elements occurring in bauxite. The behavior of lithium-bearing bauxite in the digestion process was investigated, and the effect of digestion conditions on the extraction rates of lithium was studied. The results demonstrate that the mass ratio of the added CaO to bauxite, the KOH concentration, and the digestion temperature had a significant effect on the lithium extraction efficiency. An L9(34) orthogonal experiment demonstrated that the order of each factor for lithium extraction from primary to secondary is lime dosage, caustic concentration, and reaction temperature. Under the optimal conditions (t = 60 min, T = 260 ◦C, r(K2O) = 280 g/L, and 16% lime dosage), the leaching efficiencies of lithium and alumina are 85.6% and 80.09%, respectively, with about 15% of lithium entering into red mud. The findings of this study maybe useful for controlling lithium content in alumina products and lithium recovery from the Citation: Han, D.; Peng, Z.; Song, E.; Bayer process. Shen, L.

  • Investigation of Lime Usage Impacts on Bauxite Processability at ETI Aluminyum Plant
    International Journal of Industrial Chemistry (2019) 10:57–66 https://doi.org/10.1007/s40090-019-0171-x RESEARCH Investigation of lime usage impacts on bauxite processability at ETI Aluminyum Plant Hüseyin Arıkan1 · Gökhan K. Demir2 · Sema Vural3 Received: 29 March 2018 / Accepted: 3 February 2019 / Published online: 11 February 2019 © The Author(s) 2019 Abstract ETI Aluminyum A.Ş., the primary aluminium manufacturer of Turkey, is also one of the major integrated plants of the world capable of performing production from mining until end product. The alumina refnery was designed on a certain boehmitic bauxite quality basis. However, bauxite properties have changed over the years, resulting in the urgent need for process opti- mization to not only keep the refnery cost efcient, but also prevent serious bottlenecks in the near future. Lime can be used to overcome problems when using bauxites with specifc and variable chemical and mineralogical characteristics. Although lime is extensively used when processing diasporic bauxites, the studies on boehmitic bauxites and the overall efects on the process are limited. In this paper, lime impact was investigated at all stages of the Bayer process including the efect on alumina quality, energy and raw material consumptions. The results showed signifcant improvements in the product quality as well as recordable savings on consumptions.

Although the concept of reacting aluminum metal with water to produce hydrogen is not new, there have been a number of recent claims that such aluminum-water reactions might be employed to power fuel cell devices for portable applications such as emergency generators and laptop computers, and might even be considered for possible use as the hydrogen source for fuel cell-powered vehicles. In the vicinity of room temperature, the reaction between aluminum metal and water to form aluminum hydroxide and hydrogen is the following: 2Al + 6H2O = 2Al(OH)3 + 3H2.
