Red bauxite powder mined by Guinea’s biggest producer -- flowing past a mangrove swamp on a conveyor belt and plunging through a giant funnel into the Rio Tamara ship -- has been the country’s steadiest source of income since it was first mined four decades ago.
The company churning out the ore -- owned by Rio Tinto Plc, Alcoa Inc., Dadco Alumina & Chemicals Ltd. and the government -- will also lead a new wave of investment that may spur the West African nation’s economy and more than double bauxite output, which is refined and then smelted into aluminum.
