The Primary Ore of Copper

Copper is a versatile mineral that has been in use by humans for thousands of years. It has a wide range of applications, from electrical wiring to coins and jewelry. But did you know that all copper products start as an ore? In this blog post, we’ll be taking a closer look at the primary ore used to make copper.

The primary ore used to produce copper is called chalcopyrite, which is also known as “copper pyrite” or simply “pyrite.” Chalcopyrite is a sulfide mineral composed mainly of iron and sulfur, along with trace amounts of other elements like cobalt, nickel, lead, and arsenic. It typically appears as yellowish-green cubes or pyramid-shaped crystals with striations on the faces.

Chalcopyrite can be found in many different types of rocks and geologic environments around the world; it’s especially common in areas with sedimentary deposits like shale formations. Most often, it’s mined via open-pit methods such as strip mining or quarrying; however, some operations still use underground mining techniques. Once it’s extracted from the Earth, chalcopyrite must undergo several steps before it can be used to make copper products.

The first step is crushing and grinding the ore into small pieces to be processed more easily. Next comes concentration—a process that involves separating out valuable minerals from waste materials using air bubbles or magnets. After concentration comes smelting—the process of heating the ore until it reaches temperatures high enough to liquefy its components so they can be separated into metals like copper and sulfur dioxide gas. Finally, refining removes any impurities leftover from the smelting process and creates pure copper metal for use in various applications.


As you can see, chalcopyrite is essential in producing copper products for everyday use. From electrical wiring to coins and jewelry—it all starts with this unique mineral ore!
