Ghana is inviting investors to submit plans on how to tap the nation’s bauxite deposits as the government seeks to leverage more of its mineral resources to fund infrastructure. The government will receive proposals from interested parties until the end of the year on how to expand production and build refining and smelting capacity for the manufacturing of alumina and aluminum, said Michael Ansah, chief executive officer of Ghana Integrated Aluminium. The agency was created last year to implement the government’s strategy for the industry.
