2022.4.24 This is because “dry-weight” means that the extracted soils were kiln-dried to retain only 13 per cent moisture. Whhen extracted, Jamaica’s bauxitic soils have a natural free-moisture content of 20-30 per cent. Drying reduces the weight of dirt to be shipped. Thus, bauxite mining removes water from the environment.
