Sierra Leone woos miners to clean energy with $11 billion plan
Most mining firms rely on their own diesel supplies to extract iron ore, diamonds, rutile and bauxite in the resource-rich country.
Vale has paid $6 million for a minority stake in the Boston Electrometallurgical Company (Boston Metal) as part of efforts to produce steel without carbon emissions, according to a statement on Tuesday.
Boston Metal is a pre-operational company founded in 2012 by professors at the Massachusetts Institute of Technology working on molten oxide electrolysis in order to transform iron ore for steel production without making carbon dioxide, Vale said.
