How can we ensure they are sustainably extracted while supporting the energy transition?&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/xn--anne-aurlie-ibb\/\" target=\"_blank\" rel=\"noreferrer noopener\">Anne-Aur\u00e9lie Sappin<\/a>, a research scientist at the Geological Survey of Canada and associate professor at INRS, sheds light on the issue. As an expert in economic geology, she focuses her research on the formation of REE deposits associated with magmatic rocks, using approaches such as petrology, geochemistry, mineralogy, and geochronology.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Since the dawn of time, humanity has advanced and developed through the discovery and exploitation of metals. From the Copper Age to the Industrial Revolution, mineral resources have been catalysts for progress. Today, a new transformation is taking place\u2014the technological revolution. REEs are an essential part of this revolution, as they are what make technological innovation and a greener economy possible.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-why-are-rare-earth-elements-crucial\">Why are rare earth elements crucial?\u00a0<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In 2024, Canada drew up a list of 34 elements and minerals deemed critical to its economy and security. Among them, REEs, including scandium, yttrium, and fifteen lanthanides, were identified as a top priority. Despite their name suggesting scarcity, they are relatively abundant in the Earth\u2019s crust. However, extracting them remains a huge challenge requiring complex and often costly processes.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">REEs, which are found in everyday objects such as smartphones, laptops, and LED bulbs, also play a key role in electric vehicle motors, wind turbines, and defense technologies. They are indispensable in our connected and low-carbon society.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-towards-responsible-rare-earth-element-extraction\">Towards responsible rare earth element extraction\u00a0<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Canada has some of the world\u2019s largest known REE resources and reserves. Sites like Nechalacho, Strange Lake, and Ashram have strong exploitation potential.&nbsp;<\/p>\n\n\n\n<figure data-wp-context=\"{&quot;galleryId&quot;:&quot;6a97c710d633c&quot;}\" data-wp-interactive=\"core\/gallery\" class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-2 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure data-wp-context=\"{&quot;imageId&quot;:&quot;6a97c710d70c0&quot;}\" data-wp-interactive=\"core\/image\" data-wp-key=\"6a97c710d70c0\" class=\"wp-block-image size-large wp-lightbox-container\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"768\" data-wp-class--hide=\"state.isContentHidden\" data-wp-class--show=\"state.isContentVisible\" data-wp-init=\"callbacks.setButtonStyles\" data-wp-on--click=\"actions.showLightbox\" data-wp-on--load=\"callbacks.setButtonStyles\" data-wp-on--pointerdown=\"actions.preloadImage\" data-wp-on--pointerenter=\"actions.preloadImageWithDelay\" data-wp-on--pointerleave=\"actions.cancelPreload\" data-wp-on-window--resize=\"callbacks.setButtonStyles\" data-id=\"195054\" src=\"https:\/\/inrs.ca\/wp-content\/uploads\/IMG_3833-1024x768.jpg\" alt=\"Sy\u00e9nite riche en eudialyte (mineral rose) \" class=\"wp-image-195054\" srcset=\"https:\/\/inrs.ca\/wp-content\/uploads\/IMG_3833-1024x768.jpg 1024w, https:\/\/inrs.ca\/wp-content\/uploads\/IMG_3833-300x225.jpg 300w, https:\/\/inrs.ca\/wp-content\/uploads\/IMG_3833-768x576.jpg 768w, https:\/\/inrs.ca\/wp-content\/uploads\/IMG_3833.jpg 1067w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><button\n\t\t\tclass=\"lightbox-trigger\"\n\t\t\ttype=\"button\"\n\t\t\taria-haspopup=\"dialog\"\n\t\t\tdata-wp-bind--aria-label=\"state.thisImage.triggerButtonAriaLabel\"\n\t\t\tdata-wp-init=\"callbacks.initTriggerButton\"\n\t\t\tdata-wp-on--click=\"actions.showLightbox\"\n\t\t\tdata-wp-style--right=\"state.thisImage.buttonRight\"\n\t\t\tdata-wp-style--top=\"state.thisImage.buttonTop\"\n\t\t>\n\t\t\t<svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"12\" height=\"12\" fill=\"none\" viewBox=\"0 0 12 12\">\n\t\t\t\t<path fill=\"#fff\" d=\"M2 0a2 2 0 0 0-2 2v2h1.5V2a.5.5 0 0 1 .5-.5h2V0H2Zm2 10.5H2a.5.5 0 0 1-.5-.5V8H0v2a2 2 0 0 0 2 2h2v-1.5ZM8 12v-1.5h2a.5.5 0 0 0 .5-.5V8H12v2a2 2 0 0 1-2 2H8Zm2-12a2 2 0 0 1 2 2v2h-1.5V2a.5.5 0 0 0-.5-.5H8V0h2Z\" \/>\n\t\t\t<\/svg>\n\t\t<\/button><figcaption class=\"wp-element-caption\">Syenite rich in eudialyte (pink mineral) from the <strong>Kipawa alkaline complex (Quebec).<\/strong><\/figcaption><\/figure>\n\n\n\n<figure data-wp-context=\"{&quot;imageId&quot;:&quot;6a97c710d7458&quot;}\" data-wp-interactive=\"core\/image\" data-wp-key=\"6a97c710d7458\" class=\"wp-block-image size-large wp-lightbox-container\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"768\" data-wp-class--hide=\"state.isContentHidden\" data-wp-class--show=\"state.isContentVisible\" data-wp-init=\"callbacks.setButtonStyles\" data-wp-on--click=\"actions.showLightbox\" data-wp-on--load=\"callbacks.setButtonStyles\" data-wp-on--pointerdown=\"actions.preloadImage\" data-wp-on--pointerenter=\"actions.preloadImageWithDelay\" data-wp-on--pointerleave=\"actions.cancelPreload\" data-wp-on-window--resize=\"callbacks.setButtonStyles\" data-id=\"195053\" src=\"https:\/\/inrs.ca\/wp-content\/uploads\/Strange-Lake_Picture-1024x768.jpg\" alt=\"Pegmatite granitique\" class=\"wp-image-195053\" srcset=\"https:\/\/inrs.ca\/wp-content\/uploads\/Strange-Lake_Picture-1024x768.jpg 1024w, https:\/\/inrs.ca\/wp-content\/uploads\/Strange-Lake_Picture-300x225.jpg 300w, https:\/\/inrs.ca\/wp-content\/uploads\/Strange-Lake_Picture-768x576.jpg 768w, https:\/\/inrs.ca\/wp-content\/uploads\/Strange-Lake_Picture.jpg 1067w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><button\n\t\t\tclass=\"lightbox-trigger\"\n\t\t\ttype=\"button\"\n\t\t\taria-haspopup=\"dialog\"\n\t\t\tdata-wp-bind--aria-label=\"state.thisImage.triggerButtonAriaLabel\"\n\t\t\tdata-wp-init=\"callbacks.initTriggerButton\"\n\t\t\tdata-wp-on--click=\"actions.showLightbox\"\n\t\t\tdata-wp-style--right=\"state.thisImage.buttonRight\"\n\t\t\tdata-wp-style--top=\"state.thisImage.buttonTop\"\n\t\t>\n\t\t\t<svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"12\" height=\"12\" fill=\"none\" viewBox=\"0 0 12 12\">\n\t\t\t\t<path fill=\"#fff\" d=\"M2 0a2 2 0 0 0-2 2v2h1.5V2a.5.5 0 0 1 .5-.5h2V0H2Zm2 10.5H2a.5.5 0 0 1-.5-.5V8H0v2a2 2 0 0 0 2 2h2v-1.5ZM8 12v-1.5h2a.5.5 0 0 0 .5-.5V8H12v2a2 2 0 0 1-2 2H8Zm2-12a2 2 0 0 1 2 2v2h-1.5V2a.5.5 0 0 0-.5-.5H8V0h2Z\" \/>\n\t\t\t<\/svg>\n\t\t<\/button><figcaption class=\"wp-element-caption\">Granitic pegmatite containing potassium feldspar (Kfs), arfvedsonite (Arf), aegirine (Aeg), hematite (Hem), and gittinsite (Git), from the <strong>Strange Lake alkaline complex in Quebec<\/strong> (photo by N.

The mining of minerals containing these elements, as well as the metallurgical processes needed to separate REEs from the mineral matrix, can affect the quality of soil and water near extraction sites. It is therefore crucial to use an integrated approach that considers the entire production chain\u2014from resource exploration and extraction to residue management\u2014to minimize environmental risks associated with REE exploitation.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Critical minerals are vital to the future of technology, but their extraction must be considered within a broader ecological perspective. By adopting more sustainable practices and investing in REE recycling, we can reconcile progress with the preservation of our environment.&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Environment Day is an important time to reflect on the impact of natural resource
