So, other lands may possesses adequate reserves and resources to hold up significant bauxite production for many period of time which include India, France, and so fourth. Indeed, as know bauxite is primary source of both Alumina (Al2O3) and aluminium (Al) and Aluminium derivatives such as Al alloys. Alumina is first obtained from bauxite processing via bayer process which can generate a considerable amount of by-product such as red mud. In fact, Alumina, Aluminium, and as well as red mud, all three are so beneficial in our society needs. So, here are some applications of these bauxite-derived products such as in membranes technologies, medical areas, and as well as in catalysis domains. The exploration and development membrane materials grown exponentially in recent years due to its interest in utilizing inorganic membranes, especially microporous ones as shown in Hsieh, H. P. et al's research paper . Membranes engineering for industrial effluent treatment are so attracting. In this sense, Peters. Cartwright, P. established a review to consider some of the chance offered by membrane process in this particular issue. Therefore, it is concluded that there are no easy solution, no single discipline is the for all problems. γ-alumina double-layered ultrafiltration (UF) membrane has been proposed and develop in He, Z., et al's research with novel position pore-sized active layers and single-layered (UF) membranes generated utilizing one approach with adjustment of the pore size of Al2O3 microfiltration (MF) membrane. Also, a tubular C/Cu decorated γ-alumina membranes was reported in Yakoumis' research work for NO abatement. This modified tubular γ-alumina ultrafiltration membranes with sodium alginate was used as a strained flow membrane reactors. Lee, W., et al reported a fast synthesis of long-range ordered porous Al2O3 membranes by anodization method. The fabricated porous materials shows enhanced features. By etching process of porous alumina membranes, an Al2O3 nanotubes and nanowires was elaborated in Xiao's research paper for membranes technologies. Moreover, Al2O3 engineering applications is also considered in medical technologies due to its powerful capabilities. So, it is known that metal oxide nanoparticles (NPs) possesses fortified antimicrobial properties. Indeed, Sadiq, I. M., et al an Alumina (NPs) as antimicrobial which has higher sensitivity to well known Escherichia Coli. It is described that Al oxides (NPs) possess a wide-range applications in industrial and as well as personal care products. Al2O3 NPs induce expression of endothelial cell adhesion molecules is introduced from Oesterling's research paper . Indeed, human endothelial cells treated with Al2O3 particles demonstrated enhanced adhesion of activated monocytes. However, it is reported that exposure to ultrafine particle may be a peril for the development of vascular diseases due to pathology of the vascular endothelium. Also, Vilchez-Aruani, J., et al reported the effect of nanostructured Al2O3 (NSA) insecticide in human central blood lymphocytes in vitro. In fact, results exhibits that NSA particles are nongenotoxic and non-cytotoxic at the evaluated doses and do not cause obvious DNA harm in human peripheral blood lymphocytes (PBL) in vitro. Furthermore, Buteler's group developed a nanoalumina dust as insecticide against Sitophilus Oryzae and Rhyzopertha Dominica. So, the results exhibit that insecticidal activity is dependant on particle size, morphology and surface area. However, analysis indicated that maximizing surface area, and minimizing both particle size and morphology do not ensure sole dominant factors influencing efficacy. Alumina is also largely used catalysis technologies, so here are some discussed papers concerning this powerful material. Indeed, Al2O3 substrates with cylindrical parallel pores were introduced by Rai's research group . It is suggested that such samples may be helpful for quality mass transport with reaction in catalyst orifice in single pellet reactors. Also, unsupported versus supported nickel (Ni) NPs as catalysts for steam/ ethanol conversion and carbon dioxide methanation has been discussed in Riani's group , the supported one outperformed the unsupported. Also, an steam reforming of methanol over Cu-ZnO catalysts supported on Alumina is discussed in Jones' research work the catalysts showed enhanced performances. A nickel hybrid NPs anchored on Al2O3 nanoparticles cluster is reported by for cooperative catalysis of methane dry reforming. Also, a palladium (NPs) loaded over Al2O3 surface via chemical co-precipitation route and catalytic applications is fully shown by Kumar's research team . Many technological applications were demonstrated such as Suzuki Coupling, alkyne and alkene hydrogenation, Hiyama Cross-Coupling, and as well as aerobic oxidation reactions. Naik, B et al reported a preparation of Ag NPs anchored mesoporous γ-Al2O3 catalyst and its catalytic performance for the reduction of 4-nitrophenol with enhanced activities. Furthermore, a by-product of alumina production from bauxite processing via bayer process which is red mud has been reported as an active material for catalytic applications as shown in Sushil's research paper . The use of red mud as catalyst might be good alternative to the present commercial catalysts. The offered properties of this material such as iron content in form of ferric oxide (Fe2O3), sintering resistance, considerable surface area, resistance to poisoning, and as well as it cheapest price make it an attractive candidate catalyst for many reactions and beyond. Brough's research group reported a review on the aluminium (Al) industry << state-of-the-art>> engineering, environmental consequence and prospect for waste heat recovering. It is described that Al is seemly widely used across industries due to its advanced features, generally within an alloyed form. The paper outlines the whole production process of Al from ore to the processed metallic alloy product. Geza, B et al also established an historical review on (vulnerability in the Al2O3 and primary Al industry). It is suggested that promulgated epidemiological studies and quantitative prospect data for bauxite mining and Al2O3 refining are nearly non-existent. Also, Nappi, C. reported the global aluminium industry 40 years from 1972. it is taught that today, the global Al industry has only above similitude to what it was in the early 1970 s. So, the most sensible structural changes are geographical relocation of bauxite, Al2O3, and Al production centres, shifts in the level of concentration. Nordheim, E. showed a sustainable evolution inductors of European Al industry. So, the industry study response was very positive, with an exhaust industry coverage founded on tonnage reported over 80% for 2002 and 70% for 1997 data respectively. Also, Rambabu's paper discussed about aluminium alloys for aerospace applications. A full description of Al alloys was addressed in this chapter of book Aerospace Materials and Material Technologies. Such as a brief look across of the historical evolution of aerospace Al alloys, range of current alloys with description of the alloy order. Also, a survey of the physicochemical properties was considered in within this study. At the end a critical review of some of the gaps in present aerospace Al alloy technologies was elucidated. Therefore, here it is fully shown the importance of earth mineral bauxite as it is central material for generating Al2O3, Al, Al alloys and as well as red mud product, as all three are very involved in many industrial, medical and environmental technologies. So, the exploration of this should be accelerated in our society to fulfil the mankind needs.
