Acid Resistant and Highly Silver Selective Membranes Based on Charged Nanoporous 2D‐Materials
Small, EarlyView.In this work, new membranes based on charged & nanoporous nanosheets with unprecedented selectivity to silver versus a wide range of other metallic ions are reported. Furthermore, a demonstrated and lead specific intralamellar lead pathway is demonstrated. A potential applicability for ubiquitous silver in WEEE is validated.

Models of color metal production in the Urals in the Early Iron Age
Вестник археологии, антропологии и этнографии, 2018 There were various models of metal production among the population of the Itkul and the Savromat archaeological cultures during the Early Iron Age in the Central and South Urals. The Itkul culture is a culture of miners and metallurgists.

steel research international, EarlyView.On the pathway to climate‐neutral steel production, recycling fractions will necessarily increase over time. Since alloying elements will enrich progressively, as they cannot be removed economically from the melt, processes need to be adjusted.

Development and optimization of mixed sulphide/oxide copper ore treatment at Kansanshi
Journal of the Southern African Institute of Mining and Metallurgy, 2015 The Kansanshi Mine (First Quantum Minerals Ltd) treats a mixed sulphide/oxide copper-gold vein deposit. Until June 2009, the sulphide and oxide minerals were respectively recovered by the well established xanthate flotation of sulphides and acid leaching of soluble oxide copper.

steel research international, EarlyView.A CALculation of PHAse Diagrams thermodynamic modeling for Fe–Sn–C system is carried out. The model and the developed database can be used to calculate phase diagrams and thermodynamic properties of this system over wide temperature/composition range, and a part of a larger thermodynamic database for steel and alloy system, and effectively used to ...

Outline of a Washing Treatment to Improve Electric Arc Furnace Slag Environmental Behavior
steel research international, EarlyView.This study evaluates a water‐washing treatment for electric arc furnace slag to reduce the leaching of hazardous elements (Cr, Ba, Mo, and V), enabling its reuse. The process effectively decreases leachate concentrations. Using the treated slag as a substitute aggregate in concrete reduces greenhouse gases emissions by 42.5% compared to landfilling ...

Looking for Accurate Forecasting of Copper TC/RC Benchmark Levels
Complexity, 2019 Forecasting copper prices has been the objective of numerous investigations. However, there is a lack of research about the price at which mines sell copper concentrate to smelters. The market reality is more complex since smelters obtain the copper that
