1.2.2 Alumina Production. Due to high specific transport costs of bauxite, alumina production often takes place near bauxite mines.In 2000, Australia manufactured 31% of the 50.9 million tons of alumina produced worldwide, follow by the United States (9%), China (8%), and Jamaica (7%) (Table II).Approximately 10% of the alumina produced is not converted to aluminum and is …

The kaolin sits pretty much under the bauxite, so we're already effectively stripping the top off a kaolin resource. It's a higher-value industrial mineral. Since we're already mining there and we've already got our equipment, we're exploring whether there is a sort of a bolt-on kaolin operation that we could bring to bear."
