Copper is a mineral . it is not a plant or a animal . Copper is ametallic metal. It can never be broken down into differnet substances bynormal chemical means. Copper was one of the first metals known to humans .People liked it because in it's native condition , it could easily be beaten intoweapons or tools . Copper has leg one of the most useful metals for over5000 years . Copper was probably used around 8000 BC by people livingTigris and Euphrates along the rivers . In 6000 B.C , Egyptians learned how tohammer copper into things they wanted . Around 3500 B.C , People firstlearned how to melt copper with tin to make bronze . So the period between3000 BC and 1100 BC Became known as the bronze age .
Today , some of the leading states of the copper industryare Arizona with 747,000 short tons , Utah with 187,000 short tons , NewMexico with 161,000 short tons . Some other leading countries are Chile with1,422,000 short tons , United States with 1,203,000 short tons , Soviet Unionwith 650,000 short tons , and Zambia with 596,000 short tons .
When copper is being mined , both Native copper and copper oreUsually are found. The highest grade of copper ore is pale silvery gray .Miners used to be always in danger in copper mines . Today , we have reduceda fair amount of These hazards . Miners wear hats made of iron or very hardplastic . This is to protect them from falling rocks . Lamps are usefull attached tothesis helmets in case some of the lighting in the mine goes out leaving aminer stranded in the dark . One of the biggest problems with mining is tat insomeplaces dangerous gas 's May exist , like Carbon Monoxide . In the pastWe had very cruel and inhuman ways to detect harmful gases . One of Theseways was the use of canaries . Miners would let them fly into a part of themine where a poison gas was Suspected . If there was a harmful gas, the birdwould fall over dead at the first scent of the gas. Today , we have better waysto detect gases without having those animals . We now have detection equipmentin all parts of mines . Mines alsohave top of the line fire alarms and watersystems . If a flammable gas ignites , like sulfur , the fire May Not that for years ,All which results in closing the mine . Another problem miners complain about arethe rats . Mines will have mine Often cats That hunt out the rats . These cats arewell fed and petted by most of the miners .
Most copper is found in seven ores. That Means it's mixedin with other metals like lead , zinc , gold , cobalt , bismuth , platinum , andnickel . These ores will have Usually only about 4% pure copper in themthough. Sometimes miners May only find 2 % . The things that'll make copperSuch a popular metal are silly ability Which is how easily it bends . Copper ishighly malleable and will not crack when hammered or stamped . ductility isusefull a good property and has the ability to be molded into a shape or are .Copper can be pulled into very thin wire . For example , if you took a copperbar , 4 inches ( 10 centimeters ) square , you could draw it into wire thinner thena human hair . One of the most amazing things about copper is its resistence tocorrosion . Copper will not rest. However , when the air grows damp , copperwill go from reddish- orange to reddish brown . After being in the air for vaporlong periods of time , a green film will coat the copper , called patina , All whichwill protect it from further Top corrosion .
Since copper is one of the most Widely used metals in theworld , we use it for a lot of things . Copper gives us water heaters , boilers andcooking utensils . It is used for out door power lines , cables , lamp cords , andhouse wiring . Electrical machinery like generators , motors , controllers ,signaling devices , electro magnets , and communication devices all usecopper .
