Abstract Every year millions of tons iron residue are generated as a by-product zinc production. Stabilized landfilled contains recoverable metals that could be valorized with further processing. Pyrometallurgical processing allows the recovery valuable while simultaneously producing clean slag can then utilized. A thermodynamic model was developed FactSage version 8.0. The focus on minor eleme...

Zinc contaminated steelmaking by-products such as blast furnace (BF) dust and basic oxygen (BOS) present a significant recycling challenge at integrated plants. Rotary Hearth Furnaces (RHFs) provide an attractive route for recovery of Fe Zn from these materials through carbothermal reduction the oxides in material to yield Direct Reduced Iron (DRI) crude zinc oxide. The next generation RHF proc...

In recent years, the construction industry has striven to promote environmentally friendly materials. A growing body of literature recognised fly ash-based geopolymers as a promising alternative Portland Cement. However, detailed and in-depth review specifically concerning high-temperature exposure fire resistance is still missing. This provides comprehensive summary on research progress mix de...

Vanadium slag is an important resource containing valuable elements such as Fe, V, Ti, and so on. A novel selective chlorination method for extracting these from vanadium has been proposed recently. The methods could recover with a high recovery ratio less of environmental burden, while the study on mechanism at atom level was still insufficient. Fe2SiO4 FeV2O4 are two main phases slag, iron el...

Molten chloride mixtures such as MgCl 2 –KCl–NaCl are potential thermal energy storage (TES) materials and heat transfer fluids (HTFs) for next-generation concentrating solar power (CSP) systems due to their high operation temperatures (>700°C) low costs. This ternary salt mixture with a material cost (<0.35 $/kg) is promising high-temperature TES/HTF applications, example, it cou...

Abstract The present study investigated the interfacial interaction between FeMn alloy and slags of different compositions basicity from 0.4 to 1.2 in a sessile drop furnace. Interfacial tension was measured, results were analyzed assess sensitivity applied methodology. measurement based on combining experiments, multiphase flow simulations OpenFOAM, equilibrium calculations FactSage, calculati...

Due to their remarkable magnetic properties, such as a high maximum energy product, remanence, and coercivity, NdFeB magnets are used in variety of technological applications. Because very limited recycling, numbers spent widely available the market. In addition China’s monopoly on supply most rare earth elements, there is need for recovery these critical metals, import price poses an economic ...

The harmless disposal of spent cathode carbon blocks (SCCBs) has become an urgent issue in the primary aluminum industry, and SCCBs by co-combustion pulverized coal boilers is expected to be most effective treatment method. A muffle furnace at 815 °C was used this study perform a experiment meager SCCBs. ash fusion characteristics (AFTs), microscopic morphology, minerals composition were charac...

The CaO-SiO2-MgO-5Al2O3-30FeO five (oxide) components slag system was studied by varying the magnesium oxide (MgO) content (5.7–13.6 wt.%.% MgO) and keeping basicity constant). data were analyzed using FactSage software. It observed that liquid network structure precipitation of solid particles had an impact on high-temperature viscosity foaming life. Under same (mass ratio CaO/SiO2 = 1.5) at a...

The mechanical properties and the fractured surfaces of commercial purity aluminum modified by zirconium micro-additives were investigated means experimental examination. A Al specimen was used as a reference material seven Al-Zr alloys in 0.02–0.14 wt.% Zr composition range (with 0.02 step) prepared microalloying methods. Optical microscopy to examine microstructures calculate grain sizes spec...
