Le chef de la junte militaire en Guin\u00e9e, le colonel Mamadi Doumbouya, a re\u00e7u le vendredi 8 avril 2022 un groupe de dirigeants d\u2019entreprises exportatrices de bauxite pour leur demander de pr\u00e9senter un chronogramme de construction des raffineries d\u2019alumine, promises dans leurs conventions de base.<\/p>\n

La quasi-totalit\u00e9 des entreprises mini\u00e8res \u00e9voluant dans le domaine de l\u2019exportation de bauxite dans ce pays d\u2019Afrique de l\u2019Ouest ont utilis\u00e9 depuis 1963 la promesse de construction d\u2019une raffinerie d\u2019alumine comme argument de n\u00e9gociation pour obtenir leur permis d\u2019exploitation ou leur concession mini\u00e8re.<\/p>\n

Pr\u00e8s de 60 ans apr\u00e8s, une seule raffinerie d\u2019alumine est implant\u00e9e en Guin\u00e9e, notamment celle de Friguia, contr\u00f4l\u00e9e par le g\u00e9ant de l\u2019aluminium Rouski Alumini (Rusal), depuis le d\u00e9but de ann\u00e9es 2000.<\/p>\n

Avec une production d\u2019environ 600.000 tonnes d\u2019alumine sous Pechiney (France), l\u2019usine de Fria (\u00e0 environ 160 km de la capitale Conakry), ne produit plus qu\u2019environ 450.000 tonnes de substance blanch\u00e2tre, servant \u00e0 la production d\u2019aluminium m\u00e9tal.<\/p>\n

Ces derni\u00e8res ann\u00e9es, la Soci\u00e9t\u00e9 mini\u00e8re de Bok\u00e9 (SMB) travaille sur un projet de construction d\u2019une raffinerie d\u2019alumine d\u2019une capacit\u00e9 de 1 million de tonnes par an visant \u00e0 transformer sur place une partie de sa production de bauxite. L\u2019infrastructure, dont les travaux pr\u00e9liminaires sont bien avanc\u00e9s, devrait co\u00fbter pr\u00e8s de 3 milliards de dollars USD.<\/p>\n

SMB est une soci\u00e9t\u00e9 regroupant le Singapourien Winning, le Chinois Shadong Weiqao et le franco-guin\u00e9en United Mining Supply. L\u2019Etat guin\u00e9en d\u00e9tient 15% des parts dans SMB.<\/p>\n

Pour minimiser les co\u00fbts de production et r\u00e9duire les mouvements des camions de transport, SMB a inaugur\u00e9 en juin 2021 un chemin de 135km entre les localit\u00e9s de Santou et Dapilon. Une premi\u00e8re depuis des d\u00e9cennies.<\/p>\n

A c\u00f4t\u00e9, la Compagnie des bauxites de Guin\u00e9e (CBG) n\u2019a pas encore montr\u00e9 une r\u00e9elle volont\u00e9 de construire sa raffinerie d\u2019alumine, promise depuis 1976.<\/p>\n

La CBG est contr\u00f4l\u00e9e par le consortium Halco Mining (Alcoa, Rio Tinto et Dadco) \u00e0 51%, contre 49% du capital d\u00e9tenu par l\u2019Etat guin\u00e9en.<\/p>\n

Global alumina corporation (GAC), qui regroupe Mubadala et Dubal (contre 15% \u00e0 la Guin\u00e9e) a \u00ab\u00a0renonc\u00e9\u00a0\u00bb temporairement \u00e0 sa raffinerie d\u2019alumine qui lui avait permis d\u2019obtenir une convention de base sous l\u2019ex-ministre des Mines, Alpha Mady Soumah (2002-2005).<\/p>\n

La raffinerie promise devait produire environ 2,8 millions de tonnes d\u2019alumine, avec une structure modulable pouvant produire \u00e0 terme jusqu\u2019\u00e0 4,5 millions du produit semi-fini.<\/p>\n

Suite \u00e0 l\u2019annonce de la construction de la raffinerie de GAC, l\u2019op\u00e9rateur Alcoa avait promis la construction d\u2019une raffinerie d\u2019alumine \u00e0 Kamsar. Le projet est rest\u00e9 sans suite\u2026<\/p>\n

Sous l\u2019ex-pr\u00e9sident Alpha Cond\u00e9, plusieurs annonces de projets de construction de raffineries ont \u00e9t\u00e9 faites sans que cette volont\u00e9 ne soit mat\u00e9rialis\u00e9e dans les faits.<\/p>\n

L\u2019un des projets les plus originaux en R\u00e9publique de Guin\u00e9e est celui de la compagnie chinoise TBEA (Tebian Electric Apparatus), qui a promis de construire une fonderie aluminium qui tirera son \u00e9nergie de centrales \u00e0 charbon que les Chinois comptent implanter dans le pays.<\/p>\n
