Accompagner le d\u00e9veloppement du gisement de Weda Bay Nickel<\/h2>\n

Chez Eramet Indon\u00e9sie, nous utilisons des technologies de pointe, dont l\u2019intelligence artificielle, pour extraire les minerais avec une pr\u00e9cision accrue tout en minimisant l\u2019impact environnemental. Gr\u00e2ce \u00e0 l\u2019int\u00e9gration d\u2019appareils connect\u00e9s, de drones et d\u2019analyses de donn\u00e9es avanc\u00e9es, nous optimisons chaque \u00e9tape de la gestion des ressources min\u00e9rales, de l\u2019extraction \u00e0 la manutention, au stockage et au traitement.<\/p>\n

Ces innovations sont con\u00e7ues pour renforcer l\u2019efficacit\u00e9, la durabilit\u00e9 et r\u00e9duire l\u2019empreinte \u00e9cologique de l\u2019ensemble de nos op\u00e9rations, refl\u00e9tant ainsi notre engagement en faveur de pratiques mini\u00e8res responsables et de la pr\u00e9servation de l\u2019environnement.<\/p>\n<\/div><\/div><\/div>

PT Weda Bay Nickel (WBN)<\/h3>\n<\/div>

Situ\u00e9e au Centre et \u00e0 l\u2019Est d\u2019Halmahera, dans la province des Moluques du Nord, PT Weda Bay Nickel (WBN) est une mine majeure et un \u00e9l\u00e9ment cl\u00e9 du Parc Industriel de Weda Bay (IWIP). Ses activit\u00e9s incluent l\u2019extraction du minerai de nickel ainsi que son traitement dans une usine industrielle situ\u00e9e au sein d’IWIP.<\/p>\n

Eramet a rejoint le projet en mai 2006 par l\u2019acquisition de Weda Bay Minerals Inc., une soci\u00e9t\u00e9 cot\u00e9e \u00e0 la Bourse de Toronto. En juillet 2006, Eramet a men\u00e9 des \u00e9tudes de pr\u00e9-faisabilit\u00e9, posant ainsi les bases du d\u00e9veloppement \u00e0 grande \u00e9chelle de la mine. En 2017, Eramet a renforc\u00e9 le potentiel de croissance du projet en formant un partenariat strat\u00e9gique avec le groupe Tsingshan, le principal producteur mondial d\u2019acier inoxydable.<\/p>\n

Avec ce partenariat, WBN est d\u00e9tenue \u00e0 90% par Strand Minerals Pte Ltd \u2013 soci\u00e9t\u00e9 elle-m\u00eame d\u00e9tenue \u00e0 43% par Eramet et \u00e0 57% par Tsingshan \u2013 et d\u00e9tenue \u00e0\u00a010% par l\u2019entreprise publique indon\u00e9sienne PT Antam Tbk. De part cette structure, Eramet d\u00e9tient indirectement 38,7% des parts de WBN.<\/p>\n<\/div><\/div><\/div>

La mine<\/h3>\n

La concession mini\u00e8re s\u2019\u00e9tend sur une surface de 45 065 hectares<\/strong>, dans le cadre d\u2019un contrat d\u2019exploitation de 30 ans appel\u00e9 CoW (Contract of Work), et comprend 15 gisements identifi\u00e9s et \u00e9valu\u00e9s. Les op\u00e9rations \u00e0 ciel ouvert ont d\u00e9but\u00e9 fin 2019. La couche arable est pr\u00e9serv\u00e9e pour la r\u00e9habilitation de la mine, et les mat\u00e9riaux non utilisables sont stock\u00e9s en vue d\u2019une restauration ult\u00e9rieure.<\/p>\n

Les minerais de nickel sont trait\u00e9s selon leur teneur\u202f: les saprolites<\/strong> \u00e0 teneur \u00e9lev\u00e9e et moyenne sont envoy\u00e9es \u00e0 l\u2019usine pyrom\u00e9tallurgique de WBN, tandis que les lat\u00e9rites<\/strong> \u00e0 faible teneur sont trait\u00e9es dans les installations HPAL (High Pressure Acid Leach) au sein du Parc Industriel de Weda Bay (IWIP). Sont issus de cette production, des ferroalliages de nickel (NPI) destin\u00e9s \u00e0 l\u2019acier inoxydable, ainsi que du nickel utilis\u00e9 pour les batteries sous la forme de Mixed Hydroxide Product (MHP), soutenant \u00e0 la fois les march\u00e9s traditionnels et \u00e9mergents, tels que les v\u00e9hicules \u00e9lectriques.<\/p>\n<\/div><\/div><\/div>

L\u2019usine m\u00e9tallurgique<\/h3>\n

Principal outil de production au sein du Parc Industriel de Weda Bay (IWIP), l\u2019usine m\u00e9tallurgique est situ\u00e9e \u00e0 proximit\u00e9 imm\u00e9diate de la concession mini\u00e8re. Elle poss\u00e8de quatre lignes de production de type RKEF (Rotary Kiln Electrical Furnace), o\u00f9 le minerai est s\u00e9ch\u00e9, calcin\u00e9, puis fondu dans des fours \u00e9lectriques de type EAF (Electrical Arc Furnace). Avec une capacit\u00e9 annuelle de production comprise entre 30 000 et 35 000 tonnes de nickel contenu, l\u2019usine produit un ferroalliage de nickel de basse teneur<\/strong>, contenant entre 12 et 15 % de nickel. Le parc industriel, install\u00e9 en bord de mer, h\u00e9berge de nombreuses activit\u00e9s industrielles ayant aussi des usines m\u00e9tallurgiques de transformation du nickel.<\/p>\n<\/div><\/div><\/div>
