This work describes a valorization procedure for one of the most important wastes generated during aluminum recycling, namely, saline slag. was divided in two steps: a) recovery or its compounds various fractions, and b) use those fractions synthesis zeolites: analcime (NaAlSi2O6·H2O) pollucite (CsAlSi2O6·nH2O). Saline slag ground, sieved (1 mm), washed separated into different sizes, larger another smaller than 0.4 mm. The fraction mm treated under reflux conditions with NaOH CsOH...
Aluminium was successfully extracted by treating an aluminium slag with aqueous NaOH under reflux conditions. This solution purified precipitation of silicon species addition HCl up to pH = 1, and used for preparing hydrocalumite (Ca2Al(OH)6Cl·2H2O) the coprecipitation method. The effect temperature on properties prepared microwave (MW) irradiation studied. Characterization obtained solid carried out powder X-ray diffraction (PXRD), thermal analysis, FT–IR spectroscopy, chemical electron...
Three series of layered double hydroxides (LDH) with a hydrotalcite-like structure and composition corresponding to [Mg4Al2(OH)12(CO3)]·3H2O have been prepared from common batch by applying three different aging procedures, namely, stirring at room temperature, hydrothermal treatment, microwave-hydrothermal treatment. It has found that the tested properties samples (mainly related their crystallinity) are considerably improved using Shorter times also evinced than in other two treatments;...
Several phases (α, ε2, and γ) of aluminum fluoride were prepared from precursors such as NH4AlF4, (NH4)3AlF6, β-AlF3·3H2O using various synthetic strategies. The the obtained characterized by X-ray diffraction (XRD), fluorescence, scanning electron microscopy (SEM), infrared spectra (FT-IR). structural evolution to different during thermal treatment was studied dynamic XRD experiments, differential calorimetry (DSC), thermogravimetric analysis (TGA). α- γ-AlF3 with high BET surface areas...
A simple, easily applicable method is proposed to quantify the amount of ZnO segregated during synthesis and post-synthesis treatments Zn-Al layered double hydroxides with hydrotalcite structure. The provides a feasible, easy, fast, reliable way get values for content, can be extended other compounds.

Nowadays scientific and technological advances have allowed to Mankind improve the life-style, but in this way, other problems appeared. Currently, environmental are one of most important. Many countries developed a large number laws with purpose reducing human industrial effects environment. In work, valorization procedure is for important wastes generated during aluminum recycling, namely, saline slag, finding that final solids can be used applications. The divided into two steps: 1)...
