how copper ore is refined into a usable product

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.

copper processing Definition, History, &Facts Britannica

Copper processing, the extraction of copper from its ores and the preparation of copper metal or chemical compounds for use in various products.

From Ore to Finished Product Copper

• Cached
  • Exploration and Discovery. The element Copper is found in a variety of minerals in the earth's crust. Its uses are many. On the periodic chart of elements it is identified by the symbol "Cu".
  • Mining Methods. Copper ore is extracted using two basic methods of mining open pit or underground mining.
  • Processing of Copper Ore. The first step in processing the ore removed from the mine is to break the large rocks of ore into smaller pieces. This is accomplished by a variety of subsequent processing steps.
  • Beneficiation of Copper Ore. The next step in processing is called beneficiation. This is the first step in concentrating the copper into a more useable form. Chat

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.

Copper extraction

Copper concentrates produced by mines are sold to smelters and refiners who treat the ore and refine the copper and charge for this service via treatment charges (TCs) and refining charges (RCs). The global copper concentrate market [35] was valued at US$ 81 Billion in 2019 and is projected to reach US$ 93 Billion by 2027 expanding at a CAGR of

Ore Refining an overview ScienceDirect Topics

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.

Copper Production: How Is Copper Made? ThoughtCo

26, 2019 · Copper processing is a complex process that involves many steps as the manufacturer processes the ore from its raw, mined state into a purified form for use in many industries. Copper is typically extracted from oxide and sulfide ores that contain between 0.5 and 2.0% copper.

Copper Mining and Processing: Resources and Glossary Superfund

For copper sulfide ore, smelting is a stage in the process of pyrometallurgy, in which a series of steps use heat and a chemical reducing agent to decompose the partially processed ore, drive off other elements as gases or slag (waste), and leave just the concentrated copper base behind. The final product is a copper anode slab which is then

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.
