Jamaican bauxite was not used for the war effort. The techno­ logical problems arose because the North Americans were used to the largely trihydrate and coarse-grained North and South American bauxite and not the mixed hydrate and fine­ grained Jamaican bauxite. However, after the war, because of a number of fac­
