How is Copper Extracted and Processed?

Copper extraction starts with mining, which is usually done in areas such as Chile, which has large deposits of copper. The process begins with the blasting of the ore from the open-pit or underground mines. After that the ore is conveyed to crushers where it is crushed into smaller sizes. This crushed ore is then ground into a fine powder using ball mills or rod mills. The powdered ore is then sent to flotation cells where chemicals are added to make copper minerals float to the top of the cells leaving the waste rock or gangue behind.
 
The concentrated copper ore, which is in the form of a slurry, is transported to a smelter. In the smelting process, the concentrate is exposed to high temperatures of over 1200 degrees Celsius which causes the copper to melt and separate from the unwanted materials. The molten copper known as matte is then taken to a converter where it is further refined by blowing air or oxygen through it to burn out the sulfur and iron. Last of all, the copper obtained is subjected to electrolytic refining in electrolytic cells. Here, an electric current is passed through a solution containing copper ions, and the copper ions are reduced to form pure copper which deposits on the cathode plates. This process results in high purity copper that is ready for use in different applications.

Essential Equipment for Copper Extraction and Processing

● Crushers: Employed to reduce the size of the extracted ore into more manageable sizes. These are used in the initial stage of copper extraction to condition the ore for the other processes. Types include jaw crusher, cone crusher, roll crusher, impact crusher, hammer crusher.
 
Ball Mills: Cylindrical machines that contain steel balls that help in grinding the crushed ore into a fine powder. This step is very important in the process of freeing copper minerals from the surrounding material.
 
● Rod Mills: They are similar to ball mills but the grinding media they use are long rods. They are employed when a finer particle size is not required, as they provide another way of grinding.
 
Vibrating Screens: Used after grinding to help in the separation of fine particles from the larger ones. This helps in achieving a uniform size distribution for the flotation process hence enhancing efficiency.
 
Flotation Cells: Tanks where chemicals are added to the ground ore slurry to form a froth that floats copper minerals away from waste rock. This step is important for the purpose of increasing the concentration of copper ore.
 
● Blast Furnaces: Applied in the smelting process to heat the copper concentrate to temperatures in excess of 1,200 degrees Celsius. This causes copper to melt and at the same time, the impurities are separated from copper.
 
● Flash Furnaces: Another type of furnace used in the process of smelting is a more advanced type of furnace than the blast furnace, which is characterized by a shorter time for processing and higher efficiency.
 
● Converters: Employed after smelting to refine the molten copper by blowing air or oxygen through it to remove sulfur and iron.
 
● Electrolytic Cells: Used in the last step of refining in which an electric current is passed through a solution of copper ions and the pure copper settles at the cathode plates.
 
● Thickeners: Applied in the concentration process to enhance the mass per unit volume of the slurry to ease handling and processing in the other stages.
