Mineralogical assessment and modelling of the Excalibur pyrometallurgical pilot
No full text<p>Final MSc presentation on the issues encountered during a pyrometallurgy pilot project on FeMn alloy production, such as slag viscosity, refractories corrosion and degassing.

Final MSc presentation on the issues encountered during a pyrometallurgy pilot project on FeMn alloy production, such as slag viscosity, refractories corrosion and degassing. Mineralogical (FE-SEM, QEMSCAN, EPMA), chemical (XRF, XRD) and thermodynamic modelling (ThermoCalc, MTData) studies of slag compositions. ERAMET owns three plants dedicated to high-carbon ferromanganese alloys. The plants are striving to minimize their environmental footprint, notably by recycling co-products (dust and sludge) captured at various stages in the production process. Two recipes compatible with manganese alloy production have been developed. The first is developed with Eramet Norway; it uses co-products generated at the SAUDA plant to optimize the Group's industrial furnaces. The second recipe was developed with a project funded by EIT Raw Materials, to recover and recycle the manganese contained in the various co-products. The influence of recycling these agglomerated co-products was tested in the pyrometallurgical pilot. This pilot aimed to test these new products' melting performance and suitability for industrial-scale production. Several issues were encountered during this pilot affecting the viability of the process, such as viscosity, refractory corrosion and sulphur content issues. The recipes and the products from the four pyrometallurgy trials were examined to comprehend how their properties affect the pyrometallurgical processes. The mineralogical characterization and thermodynamic modelling enabled the assessment of the matter transformations that occur during the pyrometallurgy processes and the thermochemical and physical variability of the samples. This study demonstrated that all the slags produced during the pilot do not correspond to the fluid manganosite-containing slags produced at the plant. Two major types of slag were identified. A slag with mangano-calcic olivine, omnipresent in all the trials, and a slag that contains manganosite but is highly viscous. The origin of the non-compliance of these slag products is multiple. The first one is an abnormally high reduction in the load and the coke, inducing an insufficient manganese content and a sulphur enrichment. The second is inadequate management of fluxes, resulting in an overabundance of silicon and calcium, increased by constant additions of corrosive fluorite. This implies a chemical composition favouring nucleation and balanced growth of olivine to the detriment of manganosite. The rare manganosite slags formed due to excessive manganese content, allowing massive crystallization at elevated temperatures. Therefore, the mineralogy of the slags produced during EXCALIBUR induced a viscosity too high to obtain a flow. This work enabled an understanding of the problems encountered during the pilot to optimize the ferromanganese alloy production processes.</p>
Mineralogical Exploration of Grande Cote placer (Senegal)
No full text<p>Since 2013, the society Tizir Limited, Eramet's subsidiary, has been recovering the zircons and the titanium-iron bearing oxides of the Senegal Grande Côte. This placer deposit presents a heterogeneity of mineralogical composition related to the diverse facies of sand and their distribution along the dune system.</p><p>The purpose of this first course is to characterise the various horizons of sand mineralogically, athwart the study of drilling profiles to examine the evolution of the concentration in heavy minerals, following their locations and depths, and the specificities of these horizons.</p><p>The second subject broached is the impurity issues in the minerals. A study on the origins and the contents of these anomalies with be realised. To address this issue, several analytical methods have been used, such as scanning electron microscopy (SEM), paired with the QEMSCAN© analyses.</p>
Data from: TiO2 thin films by ultrasonic spray pyrolysis as photocatalytic material for air purification
No full text<p>In this study, we showed the TiO2 thin films deposited onto window glass are practicable for air purification and self-cleaning applications. TiO2 films were deposited onto window glass by ultrasonic spray pyrolysis method. Different deposition temperatures were used in the range of 250-450 °C. The structural, morphological, optical properties and surface chemical composition were investigated to understand probable factors affecting photocatalytic performance and wettability of the TiO2 thin films. The TiO2 thin films were smooth, compacted, and adhered adequately on the substrate with a thickness in the range of 100-240 nm. X-Ray diffractometer revealed that all the TiO2 thin films consisted of anatase phase structure with the mean crystallite size in the range of 13 to 35 nm. The optical measurements showed that the deposited films were highly transparent (∼85%). The wettability test results showed that the TiO2 thin films sprayed at 350 and 450 °C and annealed at 500 °C for 1 h were superhydrophilic. The photocatalytic activity of the films was tested for the degradation of methyl tert-butyl ether in multi-section plug-flow reactor. The photocatalytic test results exhibited the highest amount of conversion of methyl tert-butyl ether, ~80%, belong to the TiO2 film deposited at 350 °C.</p><h2>Usage notes</h2><p>XRD data</p><p>The raw data of XRD patterns belong to TiO2 thin films (Fig.3a).</p><p>Raman Spectroscopy</p><p>The Raman Spectra of TiO2 films (Fig.3b).</p><p>UV-VIS spectroscopy</p><p>Total transmittance spectra for TiO2 thin films (Fig.4a).</p><p>Band gap Cal.</p><p>The raw data about band gap calculations of all samples (Fig.4b).</p><p>XPS</p><p>The data of oxygen (O1s) core level spectra of the surface of TiO2 films (Fig.5).</p><p>Degradation of MTBE</p><p>The data and calculations of the degradation of MTBE in the multi-section plug-flow photocatalytic reactor.</p>
