Book Free DemoMetallurgy is a part of science and engineering that studies metallic elements' physical and chemical properties, intermetallic compounds, and mixtures called alloys.
Metals in science and technology
Previously we have learnt about what is metal and non-metal. This chapter will help us to update our knowledge regarding metal ores, separation and purification.
Some basic questions for your knowledge and understanding:
1. You can touch, use, and see me as an essential part of your daily life; guess who I am?
Answer: Metals.
2. I am a necessary component of your kitchen collections. You cannot cook without my family's help. Do you know who I am?
Answer: Metals such as silver, aluminium, bronze and copper vessels are used for cooking.
3. In addition to providing shelter, I also assist in the transportation of goods and services. Can you guess who I am?
Answer: Metals like steel, aluminium, magnesium, lead, copper etc., used for automobiles.
The growth of the metallurgical industry leads to the manufacture of various metal alloys, which give us a large number of essential items.
Metals can be found in a variety of places. In our daily life,
Metallurgy:
Most metals are used in different aspects of human life, such as automotive, aviation, railways, home appliances, construction, electrical and electronics, medicine, computers and phones, etc.
Usage of metals in various industries
Some metals, such as sodium, potassium, calcium, iron, and so on, are necessary for the human body. Deficiency in certain metals has an impact on the metabolic process, resulting in illnesses.
As a result, metals play an essential role in our lives. In this segment, we will study how metallurgy is used to obtain metals from various sources.
Metallurgy is a science of extracting metals from their ores and modifying the metals into alloys for various uses, based on their physical and chemical properties and their structural arrangement of atoms.
A metallurgical process consists of three significant steps, which are as follows:
(i) Concentration or Separation of the ore:
It is the process of removing impurities from the ore.
Quarry ore separation
(ii) Production of the metal:
It is the process of converting ore into metal.
Melted ore to moulding metal
(iii). Refining of the metal:
It is the metal purification process.
