- Abstract
As well as costs, the development of processes for treating electric arc furnace dusts has had to focus on two main problems: the high halogen contents in the zinc oxide product and the recycling of generated by-products. Routes considered have included pyrohydrolysis, sulphatisation, addition of Mn to the Waelz kiln, double leaching of Waelz oxides, modification of the Zincex process and pyrometallurgical removal of halogens. Investigations into the hydrogen reduction of the fluorides and chlorides from EAF dust containing 46.25% ZnO, 24.48% Fe2O3, 5.49% Cl and 0.79% F are reported. Leaching in water at 70 degrees C reduced the halogen contents to 0.5% Cl and 0.5% F; hydrogen reduction resulted in partitioning of 92% of the remaining F and 57% of the Cl to off-gas, leaving 0.07 wt% F and 0.1 wt% Cl in the zinc product and 0.05 wt% F, 0.1 wt% Cl in the iron-bearing by-products. A process temperature of 960 degrees C was sufficient to extract 98% of the zinc., As well as costs, the development of processes for treating electric arc furnace dusts has had to focus on two main problems: the high halogen contents in the zinc oxide product and the recycling of generated by-products.

International audience; The ALF transcription factor paralogs, AFF1, AFF2, AFF3, and AFF4, are components of the transcriptional super elongation complex that regulates expression of genes involved in neurogenesis and development. We describe an autosomal dominant disorder associated with de novo missense variants in the degron of AFF3, a nine amino acid sequence important for its binding to ubiquitin ligase, or with de novo deletions of this region. The sixteen affected individuals we identified, along with two previously reported individuals, present with a recognizable pattern of anomalies, which we named KINSSHIP syndrome (KI for horseshoe kidney, NS for Nievergelt/Savarirayan type of mesomelic dysplasia, S for seizures, H for hypertrichosis, I for intellectual disability, and P for pulmonary involvement), partially overlapping the AFF4-associated CHOPS syndrome. Whereas homozygous Aff3 knockout mice display skeletal anomalies, kidney defects, brain malformations, and neurological anomalies, knockin animals modeling one of the microdeletions and the most common of the missense variants identified in affected individuals presented with lower mesomelic limb deformities like KINSSHIP-affected individuals and early lethality, respectively. Overexpression of AFF3 in zebrafish resulted in body axis anomalies, providing some support for the pathological effect of increased amount of AFF3. The only partial phenotypic overlap of AFF3-and AFF4-associated syndromes and the previously published transcriptome analyses of ALF transcription factors suggest that these factors are not redundant and each contributes uniquely to proper development.
