why do we need bauxite aluminum ore

The World's Leading Bauxite Producing Countries - WorldAtlas

Bauxite is a soft limonite iron ore rock with portions of its iron composition replaced by aluminum. Bauxite forms when silica leaches out from laterite soil. Bauxite does not exhibit any particular composition instead it is just an assortment of clay minerals, aluminum hydroxides, and hydrous aluminum oxides.
