INTRODUCTION
Copper is an Chemical element and mineral
The word “Copper” comes from the latin
word:”Cuprus”
Industrial metal and widely used in alloyed and un-
alloyed condition.
FOUND IN…

PROPERTIES OF COPPER
PHYSICAL
High electrical conductivity
High thermal conductivity
High corrosion resistance
Good ductility and malleability
Reasonable tensile strength
Chemical
Low reactivity (like other group 11 metals)
Multivalent (+1,+2)
GOOD DUCTILITY AND MALLEABILITY
CONDUCTIVITY
Electrical
5.96x10 at 20º c
Thermal
2.18W/m.K at 0ºc 7
EXTRACTION OF COPPER
CRUSHING,GRINDING AND
CONCENTRATION OF ORES
(1) LEVIGATION
(2) FROTH FLOATATION
(3) LEACHING
MINING OF COPPER ORE
MINERAL SEPARATION
A ROD and BALL MILL contains the ore and
heavy steel balls which break the rock up until
it resembles a fine powder.
CRUSHING,GRINDING AND CONCENTRATION OF ORES
REFINING
PURIFICATION OF COPPER
APPLICATIONS
Art and Sculpture,
Statue of liberty
Virdigris, (copper rust)
Salts used as pigments
Wiring, exploiting conductivity
Circuits
Roofing, such as Oxford
Plumbing
COPPER ALLOYS
Bronze(copper+tin/arsenic) 10% tin
Hard (resistant to scratching)
Strong (resistant to bending)
Brass(copper+zinc) 30% zinc
Hard and sonorous
Nickel silver (copper+nickel+ zinc) About 25% nickel
Used for “silver” coin
Cheap and easy to work
Copper mcx -334.95 Rs per kg
Copper wire 435 per kg
Copper vessels-depends upon size and weight
Copper sculpture-depends on design and weight
Copper price
SAMPLES OF COPPER AND ZINC
APPLICATION OF COPPER
APPLICATION OF COPPER
APPLICATION IN ARCHITECTURE
Exterior copper cladding on a modern building at Yifei Originality Street, [one of Shanghai’s art, cultural and entertainment centers.
APPLICATION IN ARCHITECTURE
Copper facade
at the Oak Park Public Library
Engraving on architectural copper encasement
at the Yin Ruins Museum, Anyang, North Henan Province,
People’s Republic of China
APPLICATION IN ARCHITECTURE
Jurassic Museum of Asturias (MUJA) in Spain,
with three-lobed copper roof designed
to resemble a dinosaur’s foot.
LIGHTNING PROTECTION
Lightning strike protection minimizes damage
to buildings during lightning terminations. This
is usually accomplished by providing multiple
interconnected pathways of low electrical
impedance to the ground.
