Abstract The adverse effects of climate change calls for the rapid transformation manufacturing processes to decrease emissions carbon dioxide. In particular, a lower footprint can be achieved by capturing dioxide at site emission. Here we review use industrial effluents, waste and residues capture Waste include steelmaking slag, municipal solid incinerator ashes, combustion fly ash, black liqu...

for beneficiation of converter slag, the role of surface phenomena on slag composition was studied. this work includes some experimental data, which were measured for basic oxygen steel (bos) slag in isfahan steel plant. all data were collected on site in the plant. the results support the idea that surface activity plays a major role in converter slag formation. it was also a new finding that ...

Dissolution of Al2O3-based inclusions are paramount during production special steel and slag engineering is key to enhance this phenomenon. This work evaluates the influence thermodynamic driving force (?C) effective viscosity (?e) on cleanliness three distinct grades composition (Steel/Slag A, Steel/Slag B C). Initial final samples were withdrawal an electric steelmaking facility. The first af...

The dephosphorization slag has a great potential as the secondary resources of manganese and phosphorus, while quite a large amount of slag is landfilled and simply reused such as cement. The objective of this study is to investigate the recovery of manganese and phosphorus by wet magnetic separation technique. The hot metal pretreatment slag (dephosphorization slag) generally contains a Ca3P2O...

This paper focuses on research concerning the ecotoxicological properties of granulated slag from the pilot production of gray iron with red mud addition and concrete composites with the application of this slag. Red mud is a hazardous waste generated in the production of aluminium oxide. Negative ecotoxicological tests are, therefore, one of the basic prerequisites for the ability to use granu...

The present paper illustrates an innovative steel processing route developed by employing hydrogen direct reduced pellets and open slag bath furnace. the reduction reactor as reductant on industrial scale. solution allows for production of from blast furnace transformed in reactor. are then melted furnaces, allowing carburization further refining. proposed is clean decarbonization industry. kin...
