As of 2005, around 15 million tons of copper were being produced each year from mineral extraction. This number has been steadily growing for the last 100 years (although copper has been used by humans for over 10,000 years, 95% of all copper ever produced has been extracted since 1900).
Although there are vast amounts of copper in the earth's crust, only a tiny fraction of it can be mined in a practical and cost-effective way using current technology. This viable copper reserve is estimated to last about 60 years at current projected growth rates. Recycling of copper is, therefore, an important part of copper production and will continue to be so.

What is the mass of silver metal produced from 6.35 g of copper?
21.6 grams
Copper is which type of solid?
Copper is a metal & solid
Is Copper II hydroxide a solid liquid or gas?
Copper Sulphate is a blue crystalline solid.
What happens when add water to copper sulphate?
An exothermic reaction occurs (this is when heat is produced). There's a link between the mass of copper sulphate and the temperature rise of the water.
Is copper carbonate a solid liguid or gas?
copper (II) carbonate is a solid
Why are particles close together?
The particles in copper are close together because it is a type of solid. Solids have a definite shape and mass. Copper is a type of metal, which is a great conductor. Any item with hardness is a solid, for copper is a solid
What is the mass of silver metal produced from 6.35 g of copper?
21.6 grams
Who was the first mass produced artist was a master of woodcutting and copper engraving?
Albrecht Durer
Why does copper sulfate change mass when heated?
Solid copper appears to gain mass when heated in air, because the copper reacts with oxygen in the air to form copper oxide. However, the actual mass of the copper does not increase; the mass of the solid increases by a value equal to the mass of oxygen removed from the air.
Does the mass stay the same in a redox reaction between iron copper sulphate?
If you are considering just the mass of the solid then no, only the amount of moles reacted for each compound will be the same. Since the molecular weight for Copper (ii) is higher than iron (ii) the mass of the solid (Cu) will increase slightly.
Copper is which type of solid?
Copper is a metal & solid
Solid copper reacts with solid sulfur to form solid copper I sulfide?
Solid copper reacts with solid sulfur to form Copper(I) sulfide. 2Cu(s)+S(s) -> Cu2S(s)
Is Copper II hydroxide a solid liquid or gas?
Copper Sulphate is a blue crystalline solid.
What is the molar mass of copperII hydroxide?
There are 2 forms of Copper(II) Sulphate, each with a different molar mass. * Copper(II) Sulphate Pentahydrate (CuSO4.5H20) This is the more common, blue, crystalline solid. it has a molar mass of: 249.7g mol-1 * Anhydrous Copper(II) Sulphate (CuSO4) This is less common to come across, it is a white powdery solid,and can be obtained by heating the pentahydrated form. Molar mass: 159.6g mol-1
What is solid copper sulfate?
Copper sulfate in the solid form are crystals
What is the state of matter of Copper 2 Sulfate at room temperature?
Copper Sulphate is a powder at room temperature, therefore it is a solid.
What happens when add water to copper sulphate?
An exothermic reaction occurs (this is when heat is produced). There's a link between the mass of copper sulphate and the temperature rise of the water.
