Copper Mining and Production Processes ExplainedThe 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.

TENORM: Copper Mining and Production Wastes Radiation Ores that contain copper in the U.S. are typically mined in large, openpits. Copper processing facilities are usually located near mining or extraction sites. Significant waste volumes are associated with copper production. Mine wastes may contain radionuclides due to their natural presence in ores and can be a source of TENORM. Uranium, which may be colocated with copper ore, may also be recovered as a side stream, if economical. However, in the United States this is not a general practice. Learn more about uranium mining. The production of copper typically includes the following processes: 1. Leaching 2. Solvent Extraction 3. Smelting

Copper mining wastes make up the largest percentage of metal mining and processing wastes generated in the United States. There is a broad range of TENORM concentrations in copper mining wastes. Mining and extraction of copper by surface or underground methods can concentrate and expose radionuclides in the waste rock and tailingstailingsThe remaining portion of a metalbearing ore after some or all of a metal, such as uranium, has been extracted.. Leaching and solvent extraction/electrowinning processes, as well as the practice of recycling raffinate at copper mines, may extract and concentrate soluble radioactive materials. In some cases, levels up to two orders of magnitude over background have been measured. View the report,TENORM in SW Copper Belt of Arizona, on the TENORM Resources webpagefor more information and specific measurements.

Some wastes from copper mines can be reused. Mixtures of crushed waste rock have been used to construct embankments, fills, or pavement bases for highways. Some studies have shown that copper tailings can be used in bricks if pyrites are first removed.

EPA's Role

The Arizona Department of Environmental Quality (ADEQ) shared the results of radiological surveys with EPA on TENORM emanating from copper mines in mid1992. These surveys show that radionuclide concentrations vary, from nearbackground levels to above maximum contaminant levels, across the state, including increases of up to 100 times background levels for all radiochemicals tested except radon222. After reviewing the data provided by ADEQ, the EPA then examined the occurrence and distribut
