At the end of the 1970s, Guinea in West Africa, which had the world's highest grade bauxite, also drew ahead of Jamaica, and is now producing about 18 million tonnes of bauxite a year. Jamaica's share of world bauxite output has therefore fallen from 18.1% in the 1970s to 8.1% of the 180 million tonnes of bauxite produced worldwide in 2005.
