Concept explainers
(a)
Interpretation:
The role of slag in metallurgy of iron has to be given.
Concept introduction:
Metallury: It is defined as branch of material deals with the extraction and utilization of metals. The extraction process applies one or more of these three types of metallurgy:
- Pyrometallurgy uses heat to extract the metal.
Electrochemical process is employed in electrometallurgy.- Hydrometallurgy depends on metal’s aqueous solution chemistry.
(b)
