Bauxite may not be a resource that receives much attention, but it contributes to many aspects of daily life and work. Bauxite ore is the world’s primary source of aluminum production.
With aluminum appearing in products ranging from airplane parts to beverage cans, many manufacturing markets need a steady source of this metal. Bauxite ore can deliver on these needs. It is also a key component of cement, food additives, and glass.
What is Bauxite and What Is It Used For?
Bauxite is a naturally occurring ore rich in aluminum-bearing minerals, primarily gibbsite, boehmite, and diaspore. It forms through intense weathering of rocks in tropical or subtropical climates around the world.
Here are the common uses of Bauxite:
• It is the primary source of alumina, which is refined to produce aluminum for construction, transportation, packaging, and electronics.
• It supports the manufacturing of abrasives, refractories, and ceramics.
• It is used in water treatment processes and in producing cement additives that improve material strength.
Uses of Bauxite in daily life are more than you’d expect, thanks to its role in aluminum production.
• It’s in beverage cans and food packaging that keep products lightweight.
• It supports corrosion-resistant parts in cars, bikes, and home gadgets.
• It contributes to cookware, foils, power lines, and building materials used daily.
How Bauxite Becomes Aluminum
To understand what bauxite is used for and how it becomes aluminum, start by looking at the composition of bauxite. Some of the compounds found in bauxite include:
- Aluminum oxide
- Iron oxide
- Silica
- Titanium dioxide
Aluminum oxide, or alumina, is the primary component of bauxite. Processors remove the impurities from the bauxite ore through bauxite beneficiation and separate the aluminum.
Ore washing is a standard means of performing bauxite beneficiation, as it represents the most effective means of obtaining the highest level of aluminum-silicon concentrates. Acid leaching and filtration are common methods to separate aluminum and silicon.
Uses of Alumina Obtained from Bauxite
Eventually, the bauxite processing results in alumina. It then undergoes a smelting process to become a metal. Some of the leading products that include aluminum metal include:
- Beverage cans
- Beer kegs
- Furniture
- Picture frames
- Cooking utensils
- Window frames
- Airplane parts
- Cooking foil
- Car parts
- Roofing panels
- Roof flashing
Some manufacturers mix aluminum powder with other metals to create alloys. Such alloys can appear in cosmetics, deodorants, toothpaste, and antacids.
Additional Bauxite Uses
Beyond aluminum production, bauxite is a source of minerals used to manufacture other everyday products.
Cement: When manufacturers include bauxite in cement formulations, it delivers improved water resistance for the hardened material, which prevents premature crumbling. Bauxite has calcium carbonate that improves the durability of cement, too.
Fertilizer: Because bauxite contains a significant amount of calcium, fertilizer manufacturers will use it to provide this vital mineral for plant growth. Magnesium, phosphorus, sulfur, and potassium also appear in bauxite, further aiding plant health.
Glass: Bauxite ore is common in window glass because of aluminum oxide. Bauxite sometimes appears in enamels, too.
Paint: The alumina from bauxite processing can improve the texture and color of certain kinds of paint.
History of Bauxite
Learning what bauxite is used for is easier when you understand the discovery of bauxite. More than 200 years ago, French geologist Pierre Bertheir worked in Les Baux-de-Provence, a village in southern France. He discovered a reddish brown rock that contained alumina, calling it bauxite to honor the location of its discovery.
Mining of bauxite deposits occurs throughout the world but primarily in Australia, Brazil, China, and India. Strip mining is the most common means of obtaining bauxite ore. Afterward, miners can replace the topsoil because of the mining process. This process returns much of the mined land to its original appearance.
