 * What is Metallurgy? **

The process involved in the removal of metals and their ores and cleansing them is known as metallurgy. The method of creating items made of metal includes, “quarrying, mine construction and smelting.” Hammering copper was the most basic form of metallurgy.



** Extraction: **

Extraction is the development of removing important metals from the ore and cleansing the extracted untreated metals into a new shape. After mining, huge pieces of the ore feed are broken down through grinding to gain small particles, so each element is either important or waste. Mining is not necessary if the ore body and physical environment are beneficial to “leaching”. Leaching “dissolves” minerals in an ore body and consequences in a solution. The solution is then gathered and processed to remove precious metals. Ore bodies regularly hold more than one valuable metal.

** Making Alloys: **

Aluminium, chromium, copper, iron, magnesium, nickel, titanium and zinc are most often used as alloys. Common alloys are arranged by combining metals in the melting state, and then the combination is poured into metal and allowed to harden. Usually, the main elements are melted first, and then the others are added to it and dissolved. The most difficult thing in making alloys is that metals have different melting points.



Physical process:
 * Mixing of the metals
 * Cold press
 * Hot press
 * Extrusion



Production:

Metallurgy is the production of metallic elements for use in “consumer products.” It includes the making of alloy, “shaping, heat treatment and surface treatment of the product.” Ferrous metals and aluminium alloys rust quickly when in a saltwater atmosphere. Metals exposed to cold may suffer a flexible to a fragile change and they can lose their stiffness. “Metals under constant stress at elevated temperatures can creep.”




 * Environmental impacts: **

In order for metals and ores to be cleaned, a large amount of energy is used to remove and process metals properly. And that’s when the use of fossil fuels comes in. Therefore polluting the environment with green house gases.

 * Teflon **


 * Colourless and odourless white powder
 * CF2 is the formula for Teflon
 * Used to make pots/pans
 * Also known as “Non-stick”


 * Pulp and Paper **


 * Pulp, a lignocelluloses material goes through a process which results in paper
 * Pulp can be produced either chemically or mechanically
 * Papermaking wood is the most common process of Pulp

** Super glue **


 * If a large amount of super glue comes in contact with skin it may cause burning
 * Dangerous for the eye, can cause irritation if in contact
 * May start asthma in some situations
 * Shouldn’t be used in cotton, it can result in fire hazards
