The bauxite is then removed from the ground and loaded onto trucks or railroad cars for transportation to processing plants. Processing. Since bauxite is composed of both hydrated aluminum oxide and hydrated iron oxide, the first step in processing aluminum is removing the iron.
This stage is more for precaution. This is to ensure that no steel makes it to the next stage. As such, at the processing plant, a magnet stands tall above the bales. They then pick every form of steel left inside the shredded pieces. This ensures that the recycled aluminum contains no steel and meets the quality standards set. Step 5. De-coating
The ore is then transported to the processing plant. Crushing. The bauxite ore is crushed and mixed with caustic soda. The mixture is then heated in a digester to dissolve the aluminum hydroxide minerals. ...

Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.
Bauxite recoveries in modern washing plants is in the range of 60–80%, however, in some of the plants, the recovery is found to be as low as 50%, as they use simple vibrating screens in place of hydro-cyclones. The quality of input bauxite, particularly silica content and targeted washed bauxite quality, dictate the washed ore recovery.
