Carbon (graphite) cathodes and anodes are used to provide free electrons for the reaction. These must be replaced fairly often as the carbon is used up in the process. ... What name is given to the process of extracting aluminium? 9. Explain why aluminium processing contributes to climate change. 10.
In the Hall–Héroult process of extracting aluminium from aluminium oxide, the electrolyte is a liquid mixture of cryolite $(ce{NaAlF6})$ and aluminium oxide $(ce{Al2O3}).$ The cathodes and the anodes are made of graphite.. During the electrolysis process, aluminium is deposited at the cathode and oxygen is liberated at the anode.

In the waste management hierarchy, recycling is preferable for extracting maximum economic value and minimizing environmental impacts. Many researchers have already investigated the recycling of metals such as Li, Ni, Co, Mn, etc., from spent LIBs (He et al., 2017a; Li et al., 2019; Yang et al., 2015; Hu et al., 2017); however, sufficient attention has not been …
A basic process is thermal treatment in the presence of caustic reagents to dissolve siliceous impurities such as quartz, feldspar or mica. The graphite concentrate is mixed with caustic reagent and calcined at elevated temperatures. After calcination the graphite is leached with water washing away dissolved impurities.
