The mine in its first stage will have a 3-million-tonne annual capacity, and infrastructure, including roads and a railway line for transport and storage, has been constructed.
"For the last 15 years, Rusal has remained one of the largest investors in the economy of Guinea. The mutually beneficial nature of our cooperation with the government of Guinea, within the framework of the Dian-Dian project, continues to contribute to improving the investment climate in this West African country," UC Rusal alumina division director Yakov Itskov said, adding that the recent commissioning means creation of new jobs for locals, as well as economic development opportunities.
Rusal owns Dian-Dian's development rights; with proven reserves of about 564 million tonnes, it is considered to be the world's largest bauxite deposit.
In 2015, the company inked an infrastructure agreement that encompassed the existing railway line in the Boke province.
Rusal's Guinea portfolio includes the Compagnie des Bauxites de Kindia (CBK) and the Friguia alumina refinery complex.
