As the Grid frequency drops below 50Hz the station will automatically trip at a pre-determined value and cut power to the smelter process for 30 minutes. All generation is sent to the grid to help stabilise the frequency and prevent a trip on the grid which would potentially black out a large swathe of the area.
The Hall–Héroult process: How primary aluminum is made. In the Hall–Héroult process, alumina is dissolved in a molten cryolite bath within a carbon-lined steel pot. Carbon anodes are inserted in the top of the bath and an electric current passes through the anodes and the bath. Oxygen atoms separate from the alumina and combine with the ...
A smelter that processes secondary raw materials operates in a similar flow. In practice, smelters will often use a mix of primary and secondary materials. The following schematic helps to visualise the main inputs & outputs for the smelting & refining process. -----Last update: August 12, 2021-----References [1] Langner, Bernd E. 2011.
consumed in the smelting process and the remaining portions (known as butts) are recycled. Anode Bake. Anodes are attached to rods and suspended into the electrolytic cells in the pot room where they are slowly consumed in the aluminium smelting process. Carbon anodes, made from petroleum coke and pitch, are often manufactured on site.
Our process QAL produces alumina. Alumina is the common name for the compound, aluminium oxide, which is extracted from bauxite using a four stage chemical process known as the Bayer process. How it works. The Bayer process was invented by Austrian scientist Karl Josef Bayer in 1887. The diagram below shows the process of producing …

The main aluminum recycling process is through smelting, a process wherein a metal is extracted, either as the element or as a simple compound, from its ore through heating beyond the melting point.
Aluminium is the most plentiful metal in the earth's crust. It is found in the form of aluminium oxide in an ore called bauxite. Alumina and bauxite are the two main raw materials in the aluminium making process. Aluminium is obtained by the electrolysis of alumina which extracts pure aluminium metal from alumina.
REDUCTION PROCESS At an aluminium smelter, alumina is poured into special reduction cells with molten cryolite at 950⁰С. Electric currents are then induced in the mixture at 400 kA or above; this current breaks the bond between the aluminium and oxygen atoms resulting in liquid aluminium settling at the bottom of the reduction cell. ...
