Question

Why is Bauxite known as a wonder metal?
A.It consists of different colours
B.It can be used with various types of metals
C.Can extract more metal from less ore
D.It comprises various mixtures

Answer 1

Hint: To answer this question, you should have an idea of industrial preference of metals. Consider the actual meaning of the term “wonder” which when given to any metal would refer to its economic and industrial advantage.

Complete step by step answer:
A wonder metal is a term which can be given to metals with high industrial advantages. In this case, bauxite is formed from a reddish clay material called laterite soil and is most commonly found in tropical or subtropical regions. Bauxite consists primarily of aluminium oxide compounds (alumina), silica (), iron oxides () and titanium dioxide () in varying proportions. Due to the corrosive resistant material, aluminium which is corrosive resistant is present in large percentage in Bauxite. Bauxite is found in various colours like white, grey, yellow, orange, red, pink, or brown. Thus, it is also known as the wonder metal. To be considered a wonder metal, the uses of bauxite include:
1.Best and only material for making aluminium.
2.Once extracted, bauxite-based alloys are used extensively in electronics, construction, vehicles and even in utensils.
3.In refractory, bauxite alloy is used as a raw material for making several products.
4.Bauxite is the main constituent material in the electric industry, aeroplane making industry, civil tool-making industry and machinery.
5.Other uses include desiccating agent, adsorbent, catalyst and in the manufacture of dental cement.
    Considering the given options and available data we can conclude that the correct answer is (B).

So, the correct answer is Option B .

Additional Information:
Other wonder metals include beryllium, magnesium, titanium, zirconium and aluminium.

Note:
Even if the student does not know about wonder metals, the question can be answered by the elimination of options as only one single correct answer exists if we consider in general the selection of any metal for industrial purposes which include: lightweight and strong, easy and feasible to extract, feasible chemical and physical treatments and usage in a large number of industries.
