Hint: You should know that an ore is a naturally occurring substance through which various valuable minerals are extracted (mostly metals are extracted). Ores are found in earth’s crust which further undergo different processes so that we get pure metal.
Complete Solution :
Given that,
- We have to figure out to which metal does the ores i.e. bauxite, diaspore and cryolite belong to.
Let us look into each ore given.
- The chemical formula of bauxite is $A{{l}_{2}}{{H}_{2}}{{O}_{4}}$ and it is the most common aluminium rich ore. It is considered as the main commercial ore for aluminium and exists in the form of sedimentary rocks. So we can say that it is definitely a rich source of aluminium to be extracted.
- The chemical formula of diaspore is $AlO(OH)$ and it is considered as one of the three component mineral ores of the economically important aluminium ore i.e bauxite. So here also we can say that diaspore is a type of aluminium ore.
- The chemical formula of cryolite is $N{{a}_{3}}Al{{F}_{6}}$ and it is also an aluminium rich ore. It is a colorless compound that forms cube-like crystallized structures.
Therefore, we can say that bauxite, diaspore and cryolite are the ores of aluminium.
So, the correct answer is “Option A”.
Note: It is important to note that bauxite is the primary ore of aluminium and is used in metallurgy, industries, etc. Usually diaspore is used as a gemstone and it is often promoted as “Zulanite”. Cryolite is used as a solvent for bauxite in the electrolytic production of aluminium.
