How does copper mining affect the atmosphere?
Waste Generation Copper mining wastes make up the largest percentage of metal mining and processing wastes generated in the United States. If pyrites and sulfides are exposed to the air and water, they may form sulfuric acid that will mobilize many metals including uranium, which is highly soluble in acid.
Why does the extraction of copper leads to air pollution?
It’s in the air and water The extraction processes are called heap and situ leaching; during these processes, particles react with each other to create acidic mists that not only harm people’s skin, eyes and lungs, but also destroy crops, deteriorate the quality of the land, and damage nearby buildings.

How does copper affect the economy?
Because of copper’s widespread applications in most sectors of the economy — from homes and factories to electronics and power generation and transmission — demand for copper is often viewed as a reliable leading indicator of economic health. This demand is reflected in the market price of copper.
What are the disadvantages of copper?
They Can Corrode Over time, copper is seriously in danger of corrosion. There’s no way to avoid it, and while you can care heavily for your cables, eventually the copper will no longer be able to hold up to the damage. Fortunately, a fiber optic cable will never corrode, thus costing you far less in the long run.

What is the only metal that conducts electricity better than copper?
Silver is the best conductor of electricity. Despite silver’s immense ability to conduct electricity, it is often not used in wiring. The reason is silver is exponentially more expensive than the other option, copper.
What is the most conductive metal on earth?
Silver
Which metal is the poorest conductor of electricity?
Bismuth and tungsten are two metals which are poor conductors of electricity.
Which metal is best conductor of electricity?
What Metal is the Best Conductor of Electricity?
- Silver. The best conductor of electricity is pure silver, but to no surprise, it is not one of the most commonly used metals to conduct electricity.
- Copper. One of the most commonly used metals to conduct electricity is copper.
- Aluminum.
What are 5 good conductors?
The most effective electrical conductors are:
- Silver.
- Gold.
- Copper.
- Aluminum.

Which is a better conductor aluminum or copper?
Copper has greater conductivity compared to aluminum, which leads to smaller (diameter) conductors being required for use. Due to its high ductile properties, copper can be formed into very fine wire. This adds to the versatility of copper wire. Copper has a high tensile strength.
Who is the best insulator?
Diamond, which is made up of nothing but carbon atoms, is also known to be an excellent insulator since it does not have any free electrons that can carry an electrical current. Other examples of good insulators include rubber, glass, air, oil, and pure water.
