Interpretation:
The chemical composition of pig iron should be determined.
Concept introduction:
An alloy is a type of substance that made by the melting of two or more elements together. In the alloy, at least one the element is a metal. The components of the alloy cannot be separated by the physical process.
The examples of alloy are brass, bronze, pig iron, chromite ore, ferromanganese, stainless steel, blister copper etc.
Interpretation:
The composition of ferromanganese alloy should be determined.
