It tends to accumulate in the flue dust of smelting furnace due to the volatility and internal circulation of the flue dust practiced in the smelting-converting process chain. The only outlets for arsenic are anodes and discard slag. Arsenic condensation in dust-free conditions was studied below 800 °C where the gas atmosphere was controlled by SO 2 -air-N 2 gas mixtures. Based on these experimental results, we confirm the kinetically constrained formation mechanism of the arsenic-containing dust, and its speciation into metallic, oxidic (III, V), and sulfidic species. The influences of temperature and atmosphere on the speciation of arsenic were compared with industrial data and discussed.

One dose of alumina contains several thousand grains, and simulating the motion of individual particles is in practice impossible. The current work proposes to model the alumina dose through a continuous formulation, using the µ (I)-rheology. The rheology is implemented as a viscosity model in OpenFOAM and initial verification cases showed an average deviation below 0.1 pct, and a benchmark case had an average deviation of 7.4 pct. A parametric study, where grains were simulated to collapse on a flat surface identified the two rheology parameters $$mu _2$$ <mml:math xmlns:mml=\"http://www.w3.org/1998/Math/MathML\"> <mml:msub> <mml:mi>μ</mml:mi> <mml:mn>2</mml:mn> </mml:msub> </mml:math> and $$I_{text{0}}$$ <mml:math xmlns:mml=\"http://www.w3.org/1998/Math/MathML\"> <mml:msub> <mml:mi>I</mml:mi> <mml:mtext>0</mml:mtext> </mml:msub> </mml:math> to be of particular importance, accounting for more than 70 pct of the variation seen. Finally, three-phase cases simulating the feeding of a dose in cryolite were conducted, and the µ (I)-rheology was able to let the parts of the dose disperse into the melt and detach, which is in accordance with what has been seen in experiments. The current work was also able to couple the model with an earlier developed solidification model, hence, creating a framework for developing a full model for alumina feeding.","PeriodicalId":51126,"journal":{"name":"Metallurgical and Materials Transactions B-Process Metallurgy and Materials Processing Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135692846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was found that an autogenous slag is formed inside the pellets prior to the melting of the metal phase. The formation of the autogenous slag started with the melting of FeO, initially located in the center of the iron grains. The liquid FeO flowed into the pore network of the pellet. While flowing, the liquid FeO dissolved parts of the residual oxides, forming an autogenous slag. The slag stayed in the pore network until the iron was molten. Upon melting of the iron, the slag coalesced into spherical droplets. The final state is reached upon the separation of the metal and slag phases by flotation, as a bulk slag was formed on the surface of the liquid iron. In addition, since the iron ore used in this study contains vanadium, the behavior of V was discussed separately based on the experimental observations to build a basis for future studies on V extraction.","PeriodicalId":51126,"journal":{"name":"Metallurgical and Materials Transactions B-Process Metallurgy and Materials Processing Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135477915","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
