Bauxite is generally extracted by open cast mining, being almost always found near the surface, with processes that vary slightly depending on the location. Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which ...
of Canada had a long-standing mining and refining process in Jamaica. Faced with Manley's strategy, the corporations had limited diversi-fication options. Kaiser took 70 percent of its bauxite from Jamaica, Reynolds 65-90 percent, and Alcoa had facilities specifically geared to the grade of Jamaican ore that made up 10-15 percent of its output.
