Processing of Mined Aluminum
The extraction of aluminum from its ore is a critical phase in the overall process of how to mine aluminum. After the raw material, bauxite, has been mined from the earth’s surface, it goes through several stages of processing to turn it into aluminum that’s fit for use.
The primary step in the processing of mined aluminum is refining. The bauxite ore contains varying amounts of aluminum oxide (Al2O3) along with other impurities like iron oxide and silica. The goal of refining is to increase the percentage of Al2O3 in the ore. This is achieved by washing the ore in a hot solution of sodium hydroxide, which dissolves the Al2O3, separating it from the impurities.
Next comes digestion. The solution obtained from refining is then pressurized and heated to break down the chemical bonds in the dissolved Al2O3, turning it into a liquid state. The impurities are filtered out, leaving behind a solution known as green liquor.
In the precipitation stage that follows digestion, seed crystals are added to the green liquor. This causes Al2O3 to crystallize out of the solution and settle at the bottom as a white powdery substance known as alumina.
Once alumina has been obtained, it undergoes smelting to produce pure aluminum. This involves heating alumina at high temperatures in a furnace and applying a strong electric current to it. The heat and electricity cause the alumina to decompose into aluminum and oxygen.
The molten aluminum thus produced is then siphoned off and cooled to form solid metallic aluminum. It can be further processed into various shapes and sizes based on its intended use.
To recap, understanding how to mine aluminum involves not only extracting bauxite from the ground but also transforming that raw material through several stages of processing into pure, usable aluminum.
