Copper is one of the oldest metals known to humanity. It has been used for thousands of years for various purposes, from jewelry and coins to wiring and pipes. But how is copper made? In this article, we’ll take a look at the step-by-step process of how copper is produced from its raw ore state through to the finished product.

Step 1: Mining Copper Ore

The first step in producing copper is finding and extracting the ore from the earth. This is typically done with large open pit mines that dig deep into the ground to access deposits of copper ore. Many times, these mines are located in remote areas or countries with limited resources, so it can be a very dangerous job. Once extracted, the ore is crushed into small pieces and transported to a processing plant where it can be further processed.

Step 2: Processing Copper Ore

At the processing plant, the ore is sorted by size and then crushed even smaller using large industrial machines. The ore is then mixed with water and chemicals that help separate any impurities before being put into tanks filled with air bubbles which help further separate any remaining impurities before being sent on for smelting.

Step 3: Smelting Copper Ore

Smelting is an essential part of producing copper. It involves heating the ore until it reaches temperatures as high as 1200 degrees Celsius (2192 Fahrenheit). This heat helps break down any impurities and allows for easier extraction of pure copper metal from the ore. The resulting liquid copper (known as blister copper) contains about 99% pure copper but still contains some other metals, including iron, nickel, arsenic, and lead, which need to be removed before it can be used in its final form.

Step 4: Refining Copper Ore

The last step in producing pure copper involves refining it further using electrolysis technology to remove any remaining impurities, such as Iron, Nickel, Arsenic, or Lead, that may have been left over during the smelting process. This process produces 99.9% pure copper that can then be used for various applications, including electrical wiring or plumbing fixtures.


As you can see, there’s much more involved than just digging up some rocks! Producing high-quality and safe products requires a complex process that begins with mining raw materials from deep underground through refining them until they are ready for use in everyday life products like wires or pipes. Understanding how this process works will help us better appreciate our everyday products made from copper!
