Bauxite - ALS

Bauxite is a mixture of aluminium minerals, clay minerals, and insoluble materials. Three aluminium minerals can occur in bauxite: gibbsite, boehmite and diaspore. Bauxite is the world's principal source of aluminium and can vary from a very soft earth to a very hard rock. It can occur as red-yellow compacted earth (both friable and re-cemented), small red round pebbles (pisolites), or large
