One such means contemplated was shipping bauxite from Jamaica, which was 1,000 miles closer to the North American mainland than the Guianas and would therefore reduce the risk of U-boat destruction or harassment.
Jamaican Bauxites Jamaican bauxites occur as pocket or blanket deposits of red earthy material on the karst surface of the Tertiary White Limestones, mainly in the interior of the island. The contact between the bauxite and the limestone is sharp, with a strong colour contrast between the dark red bauxite and the white limestone.
Bauxite mining can pollute the air, water and soil, thus directly affecting the environment. Air pollution The substances produced during the bauxite mining process include dust, sulfur dioxide (SO2), and nitrogen oxides (NOx). The mining and beneficiation of bauxite do not involve the use of chemical reagents and produces no odors.
