Slag cleaning in crossed electric and magnetic fields
(2007)
Slags from smelting of copper concentrate contains from 2% to 20% of copper and are directed to slag cleaning operation carry out in electric furnaces or other slag cleaning reactors with injection of carboneous reductant. ...
Reduction of chilean copper slags: a case of waste management project
(2005)
The Chilean copper smelters are producing large amount of copper slags. These copper slags are deposited at landfills. In the present time, a huge amount of copper slags are accumulated in Chile. The main problem with ...
Factors governing slag cleaning in an electric furnace
(2002)
Slags from the El Teniente Converter have high copper and magnetite contents. The reduction and copper impoverishment of these slags in an electric furnace were simulated in the laboratory as part of a conceptual study for ...
The reduction of Fe-bearing copper slag for its use as a catalyst in carbon oxide hydrogenation to methane. A contribution to sustainable catalysis
(Elsevier, 2020)
Reduction of Fe-phases in a slag from the copper smelting process is studied for its use as a catalyst in methanation of carbon oxide (CO). This material contains 36.4 wt% Fe and the main Fe-phases in its fresh and reduced ...
A new piece of the puzzle: slag and ore analysis to reconstruct the prehispanic smelting technology at the Atacama Desert, Chile
(SPRINGER, 2023)
The Incas appropriated many local metallurgical technologies throughout the Andes, each of which had its unique peculiarities and was based on local ancestral knowledge. The widespread use of tin-bronze during the Inca ...
Aplicação da escória de cobre batida como substituta do agregado em argamassas de assentamento e de contrapiso autonivelante
(Pós-Graduação em Engenharia CivilUniversidade Federal de Sergipe (UFS), 2023)
Exploring the Potential of Alternative Materials in Concrete Mixtures: Effect of Copper Slag on Mechanical Properties and Carbonation Resistance
(2023)
In this study, the effect on the flowability, compressive strength, absorption, sorptivity, and carbonation resistance of concrete with different copper slag (CS) replacement ratios was investigated. For this research, ...
Influence of pH on cadmium, copper, and lead removal from wastewater by steel slag
(Desalination Publ, 2016-09)
Steel slag is a byproduct of steel manufacturing which raises an important environmental concern due to the high volume of generation and, specially, its basicity. The aim of this work was to determine its recycling potential ...
