Metallurgy

Metallurgy

1. i will start with

   • History of metallurgy
     • The first form of metallurgy was with native copper
     • Its development involved 5 steps
       • Identify and discover its usefulness
       • Locate the metals in quantity
       • Extraction of minerals
       • Melt the metal
       • Form the metal into something useful
     • There were also 3 basic ages of metals
       • these are
         • Copper age
           • The use of fire makes possible important steps in the development of metallurgy
             • as they are
               • The casting of the metal
               • The smelthing of minerals
         • Bronze age
           • It is a very useful substance for humans and is a molten alloy of copper and tin
         • Iron age
           • This is the most abundant metal but it is difficult to work with

2. then comes

   • Growth in metallurgy
     • That after the 7 metals of antiquity the following were
       • Arsenic
         • Very brittle and crystalline grey steel
       • Antimony
         • Flaky and very fragile metal
     • Contemporary metallurgy
       • in which
         • A number of techniques are also used to produce synthetic metals

3. Metallurgical engineering

   • which
     • It involves the study, design, implementation and improvement of the processes that transform mineral resources and metals into useful products
   • Metallurgical engineers
     • Their job is to meet the needs of mineral and metal products in a responsible manner

4. which deals with

   • Procedures of extraction, alloying, purification and creation of useful objects form metals

5. Mineral processing

   • its main operations are
     • Crushing, concentration, sampling, analysis and dehydration
   • Processing of minerals to obtain marketable products

6. Extractive metallurgy

   • Extraction metallurgists are interested in 3 primary streams
     • Concentrated
     • Feeding
     • Waste
   • It is the study of the processes used in the separation and concentration of raw materials
