Their extraction leads to significant impacts, such as soil and water pollution and significant greenhouse gas emissions, while their processing <strong>recycling remains costly and technologically complex<\/strong>. Dependence on geopolitically sensitive regions makes supply chains vulnerable, accentuating economic risks. On the technical front, the diversity of end-of-life products and the complexity of recovery processes limit the effectiveness and widespread adoption of recycling technologies. Finally, workers' health is jeopardized by exposure to toxic substances, underlining the need to improve safety protocols and develop safer, more sustainable technologies.<\/p><p>Against this backdrop, recycling and recovery of rare metals appear to be essential solutions for reducing dependence on primary resources, limiting environmental impact and guaranteeing sustainable supplies.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-fba9b3f elementor-widget elementor-widget-heading\" data-id=\"fba9b3f\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Recycling and recovery techniques<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-096b8fb elementor-widget elementor-widget-text-editor\" data-id=\"096b8fb\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>Faced with these challenges, we cite in the following paragraphs some of the techniques studied in recent scientific literature around each of these metals.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-e9943f4 elementor-widget elementor-widget-heading\" data-id=\"e9943f4\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h4 class=\"elementor-heading-title elementor-size-default\">Rare earths: complex but essential recovery<\/h4>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-9d80379 elementor-widget elementor-widget-text-editor\" data-id=\"9d80379\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>Rare earths, used in advanced technologies such as permanent magnets and displays, pose significant recycling challenges. Acid leaching is a proven method for recovering these elements from batteries and electronic scrap. Ahn et al (2020) demonstrated that this technique could achieve a recovery rate of 99 %, by optimizing pH and temperature conditions. Another innovative approach is to use deep eutectic solvents (DES), such as the levulinic acid-choline chloride mixture, which offers an environmentally-friendly alternative to conventional leaching (Pateli et al., 2020).<\/p><p>In addition, electrochemical techniques, such as the diffusion dialysis process, enable rare earths present in hard disks and other electronic devices to be recovered with low energy consumption (Hammache et al., 2021). Finally, the use of nanomaterials to adsorb ions from rare earth-enriched wastewater has shown promising performance, with high adsorption capacities and effective adsorbent reusability (Kegl et al., 2019)...<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-495a87ac e-con-full e-flex e-con e-parent\" data-id=\"495a87ac\"
