Frequently Asked Questions Faq

Q 1. What is the heat treatment of a metal?Answer: Heat treatment is a technique used to modify the strength, ductility, toughness, hardness, and corrosion resistance of metals. Annealing, precipitation strengthening, quenching, and tempering are typical heat treatment procedures. For superior characteristics and more effective material processing, mechanical and thermal treatments are frequently combined to create what is known as thermo-mechanical treatments. High-alloy special steels, superalloys, and titanium alloys all go through these procedures.

Q 2. What is the difference between roasting and calcination?Answer: Calcination is the method of heating the ore below its melting point in a limited supply of air. This method is used for oxide and carbonate ores. For example, when the concentrated ore of zinc carbonate is heated, it produces zinc oxide and carbon dioxide is released.

ZnCO3ZnO+CO2

Roasting, on the other hand, is the process of heating the ore in an excess supply of air below its melting point. This method is applied to sulphide ores. For example, when the zinc sulphide ore is heated in the presence of oxygen, it is converted into zinc oxide and sulphur dioxide gas is produced.

ZnS+O2ZnO+SO2

There are occasions when hydrometallurgical procedures can be performed directly on the ore without any prior preparation. The ore must frequently undergo multiple stages of mineral processing as a pretreatment.

Physical Properties Of Metals

• All the metals are good conductors of heat and electricity. Cooking utensils and irons are made up of metals as they are good conductors of heat.
• Ductility is the ability of the material to be stretched into a wire. This ability allows metals to be drawn into wires and coupled with their durability, find applications as cable wires and for soldering purposes. Because Metal can be drawn into wires we can say that metals are ductile.
• Malleability is the property of substances which allows them to be beaten into flat sheets. Aluminium sheets are used in the manufacturing of Aircrafts because of their lightweight and strength. Other metal sheets are used in automobile industries, for making utensils, etc. Therefore, metals are malleable.
• Metals are sonorous because they produces a deep or ringing sound when struck with another hard object.
• Usually, all the metals have a shiny appearance but these metals can also be polished to have a shiny appearance.

Why Is Purification Of Extracted Metals Needed

The metal obtained from the extraction of metal from ore is frequently impure. It frequently contains impurities such as carbon, silicon, phosphorus, and so on.

Conversion Of Ores Into Metal Oxide

All concentrated ores are not easily reduced so concentrated ores must be converted into a form that is suitable for a reduction. Usually, sulfides and other ores are converted into oxides by following two processes. Calcination Roasting

Calcination:- Calcination is the heating of the ores in absence of . It is commonly done for oxy-ores like carbonate and sulfate.

MCo2 heat Mo + Co2

Calamine heat ZnO + Co2

Anglesite heat PbO + So3

Roasting:- Roasting is heating ores in presence of air. It is commonly done for non-oxy ores like sulfate ore. By roasting, sulfate ores can be converted to more reactive oxide for some ores partial roasting is done which is followed by self-reduction of ores.

Cast iron is a part of the iron-carbon system that includes ductile iron. Iron-manganese-chromium alloys are used in directional drilling, a non-magnetic application .

• Materials like copper alloys, titanium alloys, nickel alloys, galvanised and austenitic stainless steel and stainless steel are used to resist corrosion.

• Aluminum and magnesium alloys are often utilised when a strong, lightweight component is required, like in aerospace and automotive applications. Monel and other copper-nickel alloys are used in non-magnetic applications and very corrosive environments. Nickel-based superalloys like Inconel are used in high-temperature applications such as heat exchangers, pressure vessels, turbocharges and gas turbines.

• To lessen creep, single crystal alloys are employed at very high temperatures. Integrated circuits and Metal-oxide-silicon transistors in modern electronics require high purity single crystal silicon.

Concentration Of The Ore

The ores are extracted from the mines and there are pieces of stone, pebbles, pebbles, sand, and stones of pollutants. These residues are called gangueor matrix. The process of separating gangues present in ores obtained from mines is called concentrating of ore.

To concentrate the ore, firstly by separating large pieces of ore by hand. After this, they are broken into small pieces by handcuffs. These small pieces are put in the crushers. The crushers are like a millstone. Which consists of two plates.

One plate runs and the other plate stays level. The crushers crumble small pieces. The small pieces obtained in this way puts pieces in stamp mill. Where there are frequent hammer injuries on them. This process grinds ore into a very fine form.

Several methods can be used after grinding large pieces of ore to concentrate the ore. Depending on the nature of the ore and the gangue, one or more of these methods is sometimes used. Some of the following are the major methods.

Purification Of The Metal

The metal obtained from the extraction of the metal from the ore is often impure. It often contains impurities of carbon silicon phosphorus etc.

The method of refining of any metal depends on its nature and the nature of impurities present in it. Therefore, different types of methods are used for this. Electrolytic method is main in this. Very pure metal is obtained in this method.

The electrolytic method of refining metals can be explained by the example of refining of copper metal by this method. For the refining of copper metal, electrolyte solution of copper metal salts in electrolytic cell acts as an electrolyte, thick plates of impure metal act as anode and thin plates of pure metal act as cathode.

When electrolysed in an acidic solution of copper sulphate, thick plates of impure copper metal at the anode begin to dissolve and impurities accumulate down the solution. These impurities are called anode mud. Cu forms its cations that move into the solution.
