Determination of ZnO Amount in Electric Arc Furnace Dust and Temperature Dependence of Leaching in Ammonium Carbonate by Using of X-Ray Diffraction [PDF]

Archives of Metallurgy and Materials, 2018
Zinc is present in electric arc furnace dust (EAFD) mainly in two basic minerals, namely as franklinite ZnFe2O4 and/or zincite ZnO. While zincite is relatively reactive and easily treatable, franklinite is considerably refractory, which causes problems ...

Genetically Determined Inflammation-Related Proteins in Asthma and Type-2 Signatures. [PDF]

Allergy
This study investigates the association between genetic variation and inflammation‐related plasma proteins, and the differences in the proteins genetically determined between subjects with type‐2 signatures and/or asthma. Our findings suggest a strong contribution of genetic variation to the inflammation‐related proteome.

IRON ORE SINTER PRODUCTION USING ELECTRIC ARC FURNACE DUST AS RAW MATERIAL [PDF]

Tecnologia em Metalurgia, Materiais e Mineração, 2013
The steel production through Electric Arc Furnaces (EAF) generates approximately 15% to 20% of Electric Arc Furnace Dust (EAFD). This waste is considered dangerous due to the presence of metals as lead and cadmium that leach in contact with water ...

Off‐Gas Waste Heat Recovery for Electric Arc Furnace Steelmaking Using Calcium Hydroxide (Ca(OH)2) Dehydration

steel research international, Volume 91, Issue 11, November 2020., 2020
A novel process for extraction, storage, and utilization of off‐gas waste heat is discussed. Key difference to other concepts is the application of entrained flow Ca(OH)2 dehydration. Waste heat exchangers are avoided. Balancing of power‐off times for the reference plant requires just small heat storage tanks of 6.5 m3. In total, a net power generation
