   Introduction to global aluminum ore types Global bauxite deposit types can generally be divided into two major categories: laterite type and sedimentary type. The ore of laterite bauxite deposits is mainly gibbsite or a mixed type of gibbsite and boehmite. It is characterized by medium aluminum, low silicon, high aluminum to silicon ratio, and high iron. It is a high-quality raw material for the aluminum industry. , easy to harvest and soluble. The reserves of this type of deposit account for about 88% of the world's total aluminum ore reserves. It is the world's main bauxite deposit. It is mainly distributed in the tropical and subtropical ranges between 30° north and south latitude, generally in the offshore plains and mid-low highlands on the edge of the continent. , mesas and islands are visible. Sedimentary bauxite deposit reserves account for about 11% of the world's total aluminum ore reserves. This t…
