BHP Billiton's presentation dealt with what BHP Billiton is all about; BHP Billiton demerger; and BHP Billiton Manganese South Africa, where it was stated that approximately 70 per cent of the Manganese ore is mined at mines in the Northern Cape Province, with approximately 25 per cent of production beneficiated at the company's alloy smelter at Metalloys Smelter at Meyerton. BHP Billiton's investment in beneficiation of Manganese is consistent with the government's beneficiation strategy and downstream investment goal. Ms Jenny Cronje outlined the company's Environmental Management Strategy, covering air quality, water quality and land management. Ms Cronje highlighted BHP Billiton's commitment, stating that BHP Billiton's decision-making is based on organisational values that seek to strike a balance between the three pillars of sustainable development, as shown by BHP Billiton's contributions to ensure community development and energy efficiency projects, including practices to reduce emission and carbon footprint, and broader demonstrations of environmental responsibility.
