Copper Mining and Production Processes Explained

The ore is removed from the ground in either open pit or underground mines. Underground  sinking a vertical shaft into the earth to reach the copper ore and driving horizontal tunnels into the ore. Openpit  90% of ore is mined using the open pit method. Ores near the surface can be quarried after removal of the surface layers.

The ore is enriched using a process called froth flotation. Unwanted material (called gangue) sinks to the bottom and is removed.

This is where the chemical reactions start. The powdered, enriched ore is heated in air between 500°C and 700°C to remove some sulphur and dry the ore, which is still a solid called calcine.

A flux is a substance which is added to the ore to make it melt more easily. The solid calcine is heated to 1200°C and melts. Some impurities are removed forming a matte (a mixture of liquid copper and iron sulphide).

Air is blown into the liquid matte forming blister copper, so called because the gas bubbles trapped in the solid form blisters on the surface.

The copper is purified to 99.99% by electrolysis. The production route described above shows the progression from a rock containing about 0.2% copper to a copper cathode of 99.99% purity.

Leaching offers an alternative to copper mining. First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis. This process is known as SXEW (solvent extraction/electrowinning). Advantages of these processes are: 1. Much less energy is used than in traditional mining 2. No waste gases are given off 3. Low capital investment 4. Ability to be operated economically on a small scale. It can be used on ore with as little as 0.1% copper for this reason leaching extraction is growing in importance. It is estimated that SXEW (virtually nonexistent before 1960) will represent 21% of total copper refined production in 2019.

Another important source of copper is recycled scrap, described as secondary copper production. Around half of Europes copper demand is currently met with recycled material, making an important contribution to the circular economy. To read more about copper recycling, click here.

Transforming Copper Ore into a Refined Product

Mined copper goes through a variety of processing techniques before it is ready to be made into any copper products. Once mined, higher quality sulphide ores are processed into a more concentrated form, referred to as copper concentrates. This ore type is then refined via pyrometallurgy.

The remaining copper or the initial copper for secondary metal processing, where copper bullion levels are much lower, can be removed by selective sulfidization (i.e. fine decoppering). This is done by stirring sulfur or pyrite into the lead bath at around 330 °C.

How copper is made How Products Are Made

11 After refining, the copper cathodes are melted and cast into ingots, cakes, billets, or rods depending on the final application. Ingots are rectangular or trapezoidal bricks, which are remelted along with other metals to make brass and bronze products. Cakes are rectangular slabs about 8 in (20 cm) thick and up to 28 ft (8.5 m) long.
