Not having the same grade of popularity as other metals like rare earth elements, gold, copper, etc., strontium is a chemical element with wide uses in daily life, which why it appears EU 2023 list Critical Raw Materials. Among sources (with celestine serving raw material) used to recover element, recycling some Sr-bearing secondary wastes under consideration, and also worth mentioning interest removal from radioactive effluents. To reach these goals, several technological alternatives are being proposed, most widely adsorption or one its isotopes on solid materials. The present work reviews recent advances (for 2024) utilization diverse technologies, including leaching, adsorption, liquid–liquid extraction, recovery/elimination Sr(II) common 90Sr 85Sr radionuclides different liquid wastes. While membrane technologies useful for treating Sr-diluted solutions (in mg/L order), extraction more suitable treatment Sr-concentrated g/L order).
