What is role of graphite rod in electrometallurgy of Al?
In the electrometallurgy of aluminium, a fused mixture of purified alumina (Al 2 O 3 ), cryolite (Na 3 AlF 6 ) and fluorspar (CaF 2 ) is electrolysed. In this electrolysis, graphite is used as the anode and graphite-lined iron is used as the cathode. During the electrolysis, Al is liberated at the cathode, while CO and CO 2 are liberated at the anode, according to the following equation. If a metal is used instead of graphite as the anode, then O 2 will be liberated. This will not only oxidise the metal of the electrode, but also convert some of the Al liberated at the cathode back into Al 2 O 3 . Hence, graphite is used for preventing the formation of O 2 at the anode. Moreover, graphite is cheaper than other metals.
What process do scientist use to think about and explore the natural world?
The scientific process
What is the afferent process called?
Afferent Process is the process by which the dendrites carry impulses toward the cyton.
What are the reactants of this process?
method is process and product
What is the chemical process that uses light to process carbon dioxde in plants?
This process is called photosynthesis.
What is the electrometallurgy process - copper?
Electrometallurgy is a process that uses electricity to extract or refine metals from ores. In the case of copper, this involves passing an electric current through a copper sulfate solution to deposit pure copper onto electrodes. This process is commonly used to extract copper from low-grade ores or to refine impure copper.
What are the branches of electrometallurgy?
the main branches areELECTROWINNING ELECTROPLATING ELECTROREFINING PHYSICAL VAPOUR DEPOSITION

What are some uses and advantages of electrometallurgy?
Electrometallurgy is used in the production of various metals like aluminum, magnesium, and titanium. It offers advantages such as high purity of the produced metal, efficient energy consumption compared to traditional methods, and the ability to recycle and reclaim metals from scrap materials.
