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.

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

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.
