Quels sont les enjeux de cette nouvelle \u00e9tape ?<\/strong><\/p>\n<p><strong>Jean-Baptiste Hogard : <\/strong>Cette premi\u00e8re extension constitue une \u00e9tape majeure dans l\u2019engagement de long terme d\u2019Eramet en Argentine. Elle permettrait d\u2019ajouter 11 000 t-LCE (lithium carbonate equivalent) par an \u00e0 la capacit\u00e9 nominale actuelle de 24 000 t-LCE, renfor\u00e7ant ainsi la capacit\u00e9 de production du site. Le projet consisterait une extension du site existant, ce qui nous permettrait de tirer parti des infrastructures, de la capacit\u00e9 r\u00e9siduelle, de l\u2019exp\u00e9rience et des comp\u00e9tences d\u00e9j\u00e0 d\u00e9ploy\u00e9es \u00e0 Centenario-Ratones, tout en b\u00e9n\u00e9ficiant d\u2019une intensit\u00e9 capitalistique plus faible. Le projet repr\u00e9senterait un investissement additionnel potentiel d\u2019environ 350 millions de dollars am\u00e9ricains, sous r\u00e9serve de la d\u00e9cision finale d\u2019investissement.<\/p>\n<p>Dans ce contexte, le RIGI peut jouer un r\u00f4le important. Ce dispositif argentin d\u2019incitation aux grands investissements offre des mesures fiscales, douani\u00e8res et de change, ainsi qu\u2019une stabilit\u00e9 r\u00e9glementaire sur 30 ans. En sollicitant notre inclusion dans ce r\u00e9gime, nous souhaitons inscrire cette nouvelle phase dans la dynamique engag\u00e9e par le pays pour attirer des investissements industriels, d\u00e9velopper sa fili\u00e8re lithium et renforcer sa position dans les cha\u00eenes d\u2019approvisionnement en min\u00e9raux critiques.<\/p>\n<p><strong>L\u2019usine de Centenario devrait \u00eatre pleinement op\u00e9rationnelle fin 2026, seulement deux ans apr\u00e8s son inauguration. Quel bilan tirez-vous de cette p\u00e9riode de mont\u00e9e en puissance\u00a0?<\/strong><\/p>\n<p><strong>JBH : <\/strong>Je souhaite avant tout remercier chaleureusement les \u00e9quipes d\u2019Eramet Eramine et l\u2019ensemble des \u00e9quipes du Groupe mobilis\u00e9es depuis plusieurs ann\u00e9es sur ce projet. Atteindre 90 % de la capacit\u00e9 nominale en juin 2026, environ un an apr\u00e8s le d\u00e9marrage de l\u2019usine, conform\u00e9ment au plan de d\u00e9veloppement du projet, constitue une \u00e9tape importante. Nous progressons d\u00e9sormais vers un niveau proche de 100 % de la capacit\u00e9 nominale d\u2019ici la fin de l\u2019ann\u00e9e.<\/p>\n<p>Cette r\u00e9ussite est le r\u00e9sultat d\u2019un travail collectif, de la capacit\u00e9 des \u00e9quipes \u00e0 relever les d\u00e9fis techniques inh\u00e9rents au d\u00e9marrage d\u2019une installation industrielle aussi complexe, dans un environnement naturel difficile \u00e0 pr\u00e8s de 4 000 m\u00e8tres d\u2019altitude et de leur engagement quotidien pour stabiliser les op\u00e9rations.<\/p>\n<p>Centenario-Ratones est \u00e9galement une r\u00e9alisation technologique et industrielle majeure pour Eramet et pour l\u2019Argentine. La mont\u00e9e en puissance du site en fait aujourd\u2019hui la premi\u00e8re installation compl\u00e8te de nouvelle g\u00e9n\u00e9ration utilisant l\u2019extraction directe du lithium (DLE) \u00e0 fonctionner \u00e0 l\u2019\u00e9chelle industrielle hors de Chine.<\/p>\n<p><strong>Quel est le potentiel de long terme de Centenario-Ratones ?<\/strong><\/p>\n<p><strong>JBH : <\/strong>Centenario-Ratones est un actif qui r\u00e9unit plusieurs atouts majeurs. Le salar dispose de plus de 15 millions de tonnes LCE de ressources min\u00e9rales extractibles ce qui en fait l\u2019un des salars les plus prometteurs du \u00ab\u00a0triangle du lithium\u00a0\u00bb situ\u00e9 entre l\u2019Argentine, la Bolivie et le Chili. Les conditions g\u00e9ologiques favorables et l\u2019acc\u00e8s s\u00e9curis\u00e9 aux ressources en eau douce sont \u00e9galement des facteurs importants. Il offre donc une visibilit\u00e9 importante pour le d\u00e9veloppement de nouvelles phases \u00e0 long terme.<\/p>\n<p>Nous pouvons \u00e9galement nous appuyer sur une technologie d\u2019extraction directe du lithium d\u00e9velopp\u00e9e par Eramet, ainsi que sur l\u2019exp\u00e9rience acquise par nos \u00e9quipes depuis le d\u00e9marrage et la mont\u00e9e en puissance de l\u2019usine. Cette combinaison entre la qualit\u00e9 de la ressource, notre savoir-faire technologique et notre exp\u00e9rience op\u00e9rationnelle cr\u00e9e une base solide pour poursuivre le d\u00e9veloppement du site.<\/p>\n<p>La premi\u00e8re extension repr\u00e9sente une \u00e9tape concr\u00e8te dans cette trajectoire. Elle doit nous permettre de renforcer progressivement la capacit\u00e9 de production de Centenario-Ratones, tout en consolidant sa position parmi les actifs les plus comp\u00e9titifs de l\u2019industrie mondiale du lithium. \u00c0 plus long terme, notre ambition est de construire en Argentine une plateforme de premier plan, durable et comp\u00e9titive, cr\u00e9atrice de valeur pour le pays et contribuant \u00e0 la transition \u00e9nerg\u00e9tique mondiale.<\/p>\n<\/div><div style=\"text-align:left;\"><a class=\"fusion-button button-flat fusion-button-default-size button-custom fusion-button-default button-1 fusion-button-default-span fusion-button-default-type CTA-arrow fusion-has-button-gradient\" style=\"--button_accent_color:var(--awb-color7);--button_accent_hover_color:var(--awb-color3);--button_border_hover_color:var(--awb-color7);--button_border_width-top:0;--button_border_width-right:0;--button_border_width-bottom:0;--button_border_width-left:0;--button-border-radius-top-left:0;--button-border-radius-top-right:0;--button-border-radius-bottom-right:0;--button-border-radius-bottom-left:0;--button_gradient_angle:180deg;--button_gradient_top_color:var(--awb-custom_color_7);--button_gradient_bottom_color:var(--awb-custom_color_7);--button_gradient_top_color_hover:rgba(226,226,226,0);--button_gradient_bottom_color_hover:var(--awb-custom_color_3);--button_font_size:16px;--button_padding-right:70px;--button_padding-left:0px;--button_margin-top:30px;\" target=\"_self\" href=\"https:\/\/www.eramet.com\/fr\/news\/eramet-prevoit-de-deposer-une-demande-dans-le-cadre-du-regime-dincitation-aux-grands-investissements-rigi-en-argentine-pour-une-premiere-extension-de-centenario-ratones\/\"><span class=\"fusion-button-text\">Lire le communiqu\u00e9 de presse<\/span><\/a><\/div><div style=\"text-align:left;\"><a class=\"fusion-button button-flat fusion-button-default-size button-custom fusion-button-default button-2 fusion-button-default-span fusion-button-default-type CTA-arrow fusion-has-button-gradient\" style=\"--button_accent_color:var(--awb-color7);--button_accent_hover_color:var(--awb-color3);--button_border_hover_color:var(--awb-color7);--button_border_width-top:0;--button_border_width-right:0;--button_border_width-bottom:0;--button_border_width-left:0;--button-border-radius-top-left:0;--button-border-radius-top-right:0;--button-border-radius-bottom-right:0;--button-border-radius-bottom-left:0;--button_gradient_angle:180deg;--button_gradient_top_color:var(--awb-custom_color_7);--button_gradient_bottom_color:var(--awb-custom_color_7);--button_gradient_top_color_hover:rgba(226,226,226,0);--button_gradient_bottom_color_hover:var(--awb-custom_color_3);--button_font_size:16px;--button_padding-right:70px;--button_padding-left:0px;--button_margin-top:30px;\" target=\"_blank\" rel=\"noopener noreferrer\" href=\"https:\/\/centenario.virtual.eramet.com\/fr\"><span class=\"fusion-button-text\">Visitez le site de Centenario en r\u00e9alit\u00e9 virtuelle<\/span><\/a><\/div><\/div><\/div><\/div><\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":3,"featured_media":59275,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"inline_featured_image":false,"footnotes":""},"categories":[32],"tags":[93,747,92,652],"class_list":["post-59233","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-groupe","tag-argentine","tag-centenario-lithium-2","tag-eramine","tag-lithium","nature-actualite"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v25.9 -
