Some Fact About Copper That we Didn't Know

Copper is a name that is widely used within industrial, technological, chemical and even artistic circles. However, many people don't know much more about this metal than its current market rate or that it exists in the web of wires that feed their homes, businesses, and vehicles with power. Because of this, we've constructed a list of the most interesting things about this popular metal.

7  COPPER FACTS YOU MAY NOT BE AWARE OF:

1. Copper is widely used around the world and has been for countless centuries. In fact, humans have used copper for the past 10,000 years and possibly longer than that.

2. 95% of the copper that has been mined thus far has been extracted and smelted since 1900.

3. It is calculated that there is a big amount of copper left in just the Earth's upper kilometer of the earth crust. Experts believe that at the rate we are currently extracting copper, there is enough remaining to be mined for 5 million years. Yet, only a small percentage of these reserves are considered economically viable.

4. Copper can be found in the crust of the Earth at a concentration of around 50ppm, but it is also found synthesized in massive stars.

5. Much like aluminum, copper is completely recyclable and experiences no loss in its quality widely used in Commodity Trading Tips. In fact, in terms of volume, it takes the number 3 spot for the most popular metals to recycle.

6. Rough estimates suspect that at least 80% of the world's previously mined copper is still being used today.

7. The first believed discovery of copper places it in the Middle East during 9000 BC.

The metal copper and its alloys have been used for thousands of years. In the time period of  Roman age, copper was fundamentally originated on Cyprus, hence the origin of the nomenclature of the metal as сyprium (metal of Cyprus), later cut into short to сuprum. Its compounds are generally coming across as copper(II) salts, which always partly blue or green in colors to minerals such as phosphate and have been spreadly used periodically as pigments. 

Copper extracted naturally as native copper and was known to some of the ancient civilizations on record. It has a history of use that is at least 10,000 years old, and estimates of its discovery place it at 9000 BC in the Middle East; a copper pendant was found in northern Iraq that dates to 8700 BC. There is evidence that gold and iron were the only metals used by humans before copper. Copper smelting is known to have occurred since 5500 BC in the Balkans by a chisel from Prokuplje in Serbia. It was invented independently in other parts of the world: China before 2800 BC, the Andes around 2000 BC, Central America around 600 AD and West Africa around 900 AD.

Copper harmfulness: Gram quantities of the number of copper salts have been done vanishes attempts and produced acute copper hazardous in humans, possibly due to redox heredity and the production of reactive oxygen species that harm DNA. Corresponding qualities of copper salts (30 mg/kg) are hazardous in animals. A minimum regime value for healthy growth in rabbits has been detected to be at least 3 ppm in the diet.
