Aluminum hydroxide is imported from different sources, mainly Australia, India, Turkey, and France. It is imported in small ships, in shipments ranges between 7-12 thousand tons each. Shipments are transported by trucks to the aluminum hydroxide storage facility with the capacity of about 14 thousand tons. The hydroxide material is pulled from the storage facility by a dragger to be stored in a silo for the wet hydroxide, dried by the exhaust gases of the Unit, stored in the dry hydroxide silo, and then, dragged to Reactors Feeder, where it feeds each of the 4 reactors with a specific quantity of aluminum hydroxide and Fluosilicic acid. By the completion of the reaction, the resulting mixture would be consisting of the solvent aluminum fluoride, and silica sand. Sand is then removed by a filtration belt, and disposed onto the belt carrying gypsum from the Phosphoric Acid Unit.
Solvent aluminum fluoride is then sent to 16 crystallizers to be separated by a filtration belt, dried through roasting in special equipment using burnt diesel, and packed according to demand in 25 kg, 50 kg, or 750 kg bags as demanded.
Aluminum fluoride is used in extracting Aluminum from its ores by lowering the melting point in the electrical cells during the manufacturing process.
