Copper Iron (CuFe) Iron improves the corrosion resistance and the resistance to impingement attack of copper nickel alloys. Iron acts as a grain refiner in brass. In aluminium bronzes, iron refines the structure and has a beneficial influence on the mechanical properties, in particular on the tensile strength.

Eritrea receives substantial income from foreign companies mining gold, copper, zinc, and nickel in the country. Government has 40 percent ownership in these companies.
Refined copper has also been widely used as an input into consumer goods (27%), industrial equipment (6%), transportation (6%), and other sectors (5%).4 Chinas Copper Production China is the largest global producer of copper, even though it mines a limited supply of copper ores.
The Democratic Republic of Congo. The fifth largest copper producer in the world is the Democratic Republic of Congo at 1,030,000 tonnes annually. Though the DRC does not have the highest production rate, the second largest copper reserves in the world can be found within its borders. The slightly lower production here may be explained by a lack of appropriate technology.

An excess of copper (II) sulfate solution (to make sure that all the iron is reacted) will be added to a known amount of iron. The metallic copper produced will be weighed. These weighings will be used to calculate the moles of iron used and the moles of copper formed. If equation (1) is correct, the moles of copper should equal the moles of iron.
