It is necessary that the substitutes can replace the main ingredient (minerals in this case) ? Why or why not? Discuss.

Ans:- Why Yes substitutes can replace the main ingredient substitutes is used when there is any particular thing is available in scare condition.

As in the case of “SOUTH AFRICA’S MINERALS”, South Africa Plays key role in producing of several vital minerals. They produce huge amount of chromium, used in stainless steel and an important fraction of the total world output of manganese. If the supply of these minerals is not availed in present time to due to scarcity of these minerals. Then the solutions is to find substitutes for the South African Minerals. For many uses, Aluminum is working stainless steel other metals and ceramics, through not as efficient, could replace platinum as a catalyst.

Why not

If we denote use the substitutes for the usage of minerals then the natural minerals would be totally scared from the world. During world war II, manufacturers learned to use synthetic rubber when natural rubber become almost not existent. When one particular thing is become more expensive then one should go for substitute of that thing which less expensive
So, this is not totally necessary that the substitutes can replace the main ingredient. Substitutes can replace the main ingredient up to some extent but not replace the whole thing. Like for many uses, aluminum and manganese could replace Chromium in making stainless steel.
