hydroxide precipitated from a sodium aluminate solution in crystalline form, and subsequently the ‘Bayer process’ was developed [45]. Globally, the main alumina extraction processes include the Bayer method... to the composition of bauxite and the alumina extraction process [50, 51]. However, the chemical composition of bauxite residue mainly includes Na2O, Al2O3, Fe2O3, SiO2, TiO2 and CaO. Approximately 95% of the global......
or extraction of sand from bottom of Oueme river Figure 14 Excavating of riverbed sand and impact on bank slide [75] The observed geological phenomenon is a mass sliding occurring at the bend of the Oueme...-perception or ignorance of the existence of these risks by the populations results in a recklessness or a lack of civic responsibility which is translated by the anarchic extraction of sand......
release from the η-Zn phase. This change in the behavior of the heat flow may be related to the influence of the viscosity of the liquid on the velocity of heat extraction by conduction along  ... of heat extraction.
