Guinea has signed a non-binding agreement with a subsidiary of Emirates Global Aluminium for the construction of a major alumina refinery, the second one in the country, two senior officials of Guinea’s mines ministry told Reuters. The agreement, known as a “Term Sheet”, said the company, through its Guinea Alumina Corporation (GAC), will build the two-million metric ton capacity refinery by September 2026 in the west of the country. Initial production is expected at 1.2-million tonnes annually.
