These plants are situated in Iceland to take advantage of its abundance of hydroelectric and geothermalelectric energy that is important for smelting aluminum from alumina.

Incidentally, the extraction plants are not in Reykjavik but some distance away.

Why aluminium is cheaper to extract than gold even though the extraction method is more complicated?

Bauxite ore is the base for aluminium and is more plentiful than gold ore. It is also cheaper to polish to the finished product. Aluminium has many more uses than gold so is readily adaptable to the consumer market. by Ruwayda :)

What are the two processes in the extraction of aluminium that require large amounts of energy?

The two processes in the extraction of aluminium that require large amounts of energy are electrolysis of alumina to produce aluminium metal and the production of alumina from bauxite through the Bayer process. Both processes involve high temperatures and consume significant amounts of electricity.


What are the most important types of extraction process in pharmacognosy?

The most important types of extraction processes in pharmacognosy are maceration, percolation, Soxhlet extraction, and steam distillation. Maceration involves soaking the plant material in a solvent to extract the desired compounds. Percolation uses gravity to move the solvent through a column of plant material. Soxhlet extraction continuously cycles the solvent through the plant material. Steam distillation utilizes steam to extract essential oils from plant material.


What is the role of 2-mercaptoethanol in plant protein extraction?

2-mercaptoethanol is a reducing agent that helps break disulfide bonds in proteins, allowing for better extraction of plant proteins. By disrupting these bonds, 2-mercaptoethanol helps to solubilize proteins and prevent their aggregation during the extraction process.

Why is pure aluminium oxide mixed with cryolite before electrolysis?

Pure aluminium oxide is mixed with cryolite in electrolysis of aluminium because cryolite lowers the melting point of the mixture, making the process more energy-efficient. This allows the aluminium oxide to dissolve in the molten cryolite and conduct electricity more easily, leading to the extraction of aluminium metal from the ore.
