Extraction of Rare Earth Metals from Coal Ash Using Mild Lixiviants in a Single Step Processmining. There is a significant escalation in the quantity of coal ash production, as well as the need for REE in modern-day advanced technological products. The utilization of coal ash, knowing its REE enrichment, has been a persistent area of research and development. Our approach is to extract REE

Separation of Scandium by Phosphinic Acid Extractant from Sulfuric Acid Solutionxtraction process is required for a high separation degree. The presence of contaminants such as iron and aluminum in a concentration 1000 times higher than scandium is a problem to be overcome. The present study aims at the separation of scandium from the sulfuric acid solution using Cyanex 923 in

Extraction Behaviors of Vanadium(V) with Unacidified and Acidified N1923 from a Real Leachate of Vantaining leachate obtained from vanadium-titanomagnetite was employed for the solvent extraction. The primary amine N1923 is selected for vanadium recovery from the feed solution with a high vanadium concentration of 29.21 g/L. The effects of initial pH of feed solution on the vanadium extraction wit
