Recovery of Iron, Chromium, and Nickel from Pickling Sludge Using Smelting Reduction

Metals, 2018
This paper reports the recoveries of iron, chromium, and nickel from pickling sludge using coal-based smelting reduction. The influences of slag basicity (CaO/SiO2, which is controlled by high phosphorus oolitic hematite iron ores), reduction temperature,

Design Matters: How Cell Architecture Shapes the Performance, Cost, and Environmental Impact of Battery Technologies

Advanced Energy Materials, EarlyView.
This study introduces a multidimensional framework integrating electrical performance, cost, and life cycle assessment for 140 real and virtual battery cells. Results show that LFP offers low emissions and costs, sodium‐ion excels in resource efficiency, and pouch housings and higher energy densities effectively reduce environmental burdens.

Sb recovery from an As pre-removed lead anode slime using a ZnS-Na2CO3 smelting reduction [PDF]

Journal of Mining and Metallurgy. Section B: Metallurgy
Lead anode slime is produced in large quantities during lead electrolysis, which has a high Sb content of 10-50 wt% and can be easily recycled. However, in a general alkaline pressure leaching process for pre-removal of As, Sb was partially converted to ...

Thermodynamic Study of H₂-FeO Based on the Principle of Minimum Gibbs Free Energy

Metals, 2023
Studies have shown that the reduction of wustite is the limiting factor in the ironmaking process, whether in hydrogen-based shaft furnaces, hydrogen-rich blast furnaces or smelting reduction vessels.

Energy consumption in smelting reduction (SR) processes [PDF]

Rem: Revista Escola de Minas, 2010
In contrast, conventional processes use coke and hematite/sinter in the blast furnace, in SR processes, other alternative fuels and iron ore sources, like charcoal and fine iron ores, can be used to produce sponge iron. The use of these alternative sources, by SR processes, can reduce environmental impacts and lower production costs.

Impact of Discharging Methods on Electrode Integrity in Recycling of Lithium‐Ion Batteries

Advanced Energy Materials, EarlyView.
Electrical and electrochemical discharge methods for end‐of‐life lithium‐ion batteries are compared. Electrochemical discharge better preserves the composition and layered structure of Ni‐rich cathode materials while minimizing residual lithium compounds.

Energy Consumption and CO₂ Emissions in Ironmaking and Development of a Novel Flash Technology

Metals, 2019
The issues of energy consumption and CO2 emissions of major ironmaking processes, including several new technologies, are assessed. These two issues are interconnected in that the production and use of fuels to generate energy add to the total amount of ...

Mobility of antimony, arsenic and lead at a former mine, Glendinning, Scotland [PDF]

, 2015
Elevated concentrations of antimony (Sb), arsenic (As) and lead (Pb) in upland organic-rich soils have resulted from past Sb mining activities at Glendinning, southern Scotland. Transfer of these elements into soil porewaters was linked to the production
