Dear Student,

Metallurgy is defined as a process that is used for the extraction of metals in their pure form . Metallurgy deals with the process of purification of metals and the formation of alloys.

Principles of Metallurgy :-

• Crushing and grinding
• The concentration of ores
• Hydrolytic method
• Magnetic separation
• Froth floatation
• Roasting and calcination

Happy Learning!

Metallurgy has been leading human civilization from time immemorial. Man knew how to extract metals from ores, how to alloy metals to make them suitable for specific needs, and how to prepare high-purity metals and compounds for electronic applications. Looking back into the last century, it may be said that developments in metallurgy and materials science have played a significant role in several areas and impacted the economy and well-being of people. Every other branch of science and engineering has depended on advances in metallurgy to be applied in its domain. Development of superalloys for jet engine applications, development of carbon-carbon composites for wings of wide-bodied aircrafts, high-temperature superconductors, etc. are only a few examples to quote. It should also be mentioned here that the availability of excellent high-resolution techniques has contributed immensely to the understanding of the science and technology behind these developments, particularly from the point of view of structure-property correlations coupled with phase transformations.
