UC RUSAL (SEHK: 486, EuroNext: RUSAL/RUAL), the world's largest aluminium producer, announces the restart of operations at its Ewarton Works in Jamaica. The refinery is part of Windalco, which was mothballed in 2009 due to the global economic downturn. The total capacity of the Ewarton refinery is about 650,000 tonnes of alumina per year. RUSAL plans to produce about 321,000 tonnes of alumina from the refinery by the end of this year.
