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 ...
Characterization of mixed waste of granite and LD slag
(ESCOLA DE MINAS, 2011)
This study focuses on the technical feasibility of the utilization of waste from the cutting of granite to adjust the chemical composition of slag from steelworks LD, targeting the addition of clinker Portland cement. For ...
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 ...
Characterization of Slags Produced During Gold Melting Process
(Elsevier, 2015-06)
In the extractive metallurgy of gold ores the cyanidation and melting processes are generally applied. These processes allow obtaining the “dore”. The slag generated during the melting process presents various characteristics, ...
Industrial Byproduct-Based Concrete Subjected to Carbonation. Electrochemical Behavior of Steel Reinforcement
(ESG, 2012)
Samples of ASTM A-706 structural steel embedded in different concretes obtained from mixtures of alkali-activated steel slag and fly ash were exposed to accelerated carbonation under controlled conditions (4% CO2, 65% RH ...
Study of the expansive behavior of ladle furnace slag and its mixture with low quality natural soils
(Construction and Building Materials, 2020)
Characterization of the lead smelter slag in Santo Amaro, Bahia, Brazil
(2011)
For 33 years, a primary lead smelter operated in Santo Amaro (Brazil). Since the 1970s, large amounts of Pb and Cd have been widely documented in the blood and hair of people living near the smelter. The plant
closed down ...
Crystallization kinetics of glass prepared with foundry slag
(2021-07-01)
Iron foundry slag and hydrated lime were used in glass preparation by the melt-quenching method. The glass obtained was heat-treated using the thermal analysis technique. A crystallization kinetics study was carried out ...
Reduction of Chromium from Al(2)O(3)-CaO-SiO(2)-CrOx Slags by Carbon Dissolved in Liquid Iron
(IRON STEEL INST JAPAN KEIDANREN KAIKAN, 2011)
The goal of this work is to investigate the reduction of chromium from a quaternary slag by carbon dissolved in liquid steel. Laboratory scale experiments were conducted to study the reduction of chromium oxides in the ...
Fracture characterization of roller compacted concrete mixtures with blast furnace slag and industrial sand
(2011-07-01)
The global energy crisis and growing environmental concerns have prompted manufacturers in general to intensify their efforts to reuse the by-products and wastes they generate. In metallurgy, steel production generates ...
