“The influence of increased NaCl:KCl ratios on Metal Yield in salt bath smelting processes for aluminium recycling”
نویسندگان
چکیده
Strongly increased KCl prices force to modify the current salts mixture in the currently used salt treatment processes for aluminium recycling. This study presents lab-scale results about the influence on metal yield varying both the NaCl:KCl ratio from 70% to 100% NaCl and the CaF2content from 0% to 3%. The metal yields showed no significant difference at higher NaCl:KCl ratios and as commonly known for standard mixtures a slight increase was observed with rising CaF2 values in the salt mixture, also when the NaCl content exceeded 70% wt.

Aluminium salt slag characterization and utilization--a review.
Aluminium salt slag (also known as aluminium salt cake), which is produced by the secondary aluminium industry, is formed during aluminium scrap/dross melting and contains 15-30% aluminium oxide, 30-55% sodium chloride, 15-30% potassium chloride, 5-7% metallic aluminium and impurities (carbides, nitrides, sulphides and phosphides). Depending on the raw mix the amount of salt slag produced per t...
متن کاملTechnology Development, Energy Consumption, Greenhouse Gases Emission and Environmental Pollution in Aluminium Industries
Aluminium is the world’s second most-used metal after steel and the aluminium production industry is the largest, in volume of metal produced, in non-ferrous metal industry. In this study, results of the material flows (country and global scales) related to the production and use of aluminium and energy consumption in 1980 to 2012 were separately analysed. Also, overview of the current status o...
متن کاملInfluence of Notch Depth-to-Width Ratios on J-Integral and Critical Failure Load of Single-Edge Notched Tensile Aluminium 8011 Alloy Specimens
In this paper, the influence of notch depth-to-width ratios on J-integral and critical load of Aluminium 8011 alloy specimens with U-notch under Mode I loading are studied. Using experiments, for a set of specimens having different notch depth–to–width ratios, J-integral was found and the same was verified using analytical methods. Further, using the results obtained from the experiments, failu...
