Copper mining is the lifeblood of the Zambian economy, generating three-quarters of the countrys foreign exchange earnings. Copper is equally important to western and newly industrialising countries such as China, where it is used for electrical wiring, phone and internet lines, computers and cars. Increased demand for these goods in countries such as China has resulted in a boom in international copper prices reminiscent of the late 1960s and 1970s, when Zambia was a middle-income country, with one of the highest gross domestic products (GDPs) in Africa. With its large reserves of high-quality copper, Zambia should be benefiting handsomely from the current boom.
The copper mining industry, thus defined, has two types of final product: ores and concentrates. Ores are, of course, produced by all copper mines, but in most cases the ores as taken from the earth are not sufficiently rich in metal or simple in mineralogy to be smelted directly. Hence most ores are subjected to a preliminary treatment designed to expedite the subsequent extraction of their metallic content. This treatment, variously known as ore dressing, concentrating, milling or beneficiating, involves, essentially, reducing the amount of barren rock in which the metal is imbedded and, when the ore contains metals other than copper, separating the important metallic constituents of the ore into products in each of which one metal predominates. The products resulting from this treatment are known as concentrates because, basically, they consist of ore that has been concentrated into smaller bulk through the removal of waste.

Along with drill rigs, blasting tools, and earth movers, the industry looks to feeders, screeners, and grinding mills. When mined materials are moved from the mine or quarry to the surface, sorting area, or factory, feeders keep the process running smoothly by moving the elements in the correct flow rate, to the correct place. Along with feeders, screeners take on a substantial load by filtering out the wanted substances from the unwanted. For example, a vibratory screener may allow for particles of dirt, rocks, and dust to fall away, leaving the valuable material moving towards its destination. Grinders also help to remove excess material for easier collection of goods. This is often done through crushing, grinding, or breaking down larger chunks of material to extract the desired product.
The mining industry has made great strides in extracting deposits and removing the desired material from waste. Mining machines are now more efficient because updated technology saves energy and reduces the number of harmful chemicals needed to extract desired material from its surroundings. Heavy duty, weather-resistant equipment is still necessary to extract, transport, and process minerals, ores, coal, and precious metals from soil, sand, and rock.
GK equipment properly activates and regulates the flow of material and can easily be integrated throughout your process line. Innovative mining equipment from GK is more compact and able to process material efficiently, increasing a mining companys ability to invest in superior machinery without breaking the budget.

The largest copper mining countries in the world have an increasingly important role producing a metal that underpins major global industries and will be a crucial ingredient of the transition to a low-carbon energy system.
Due to its high thermal and electrical conductivity, copper is used widely in construction, engineering and electronics manufacturing, while its malleable properties make it particularly suited to use in wiring.
As the global energy system integrates a greater share of renewable technologies and electrified processes, demand for the reddish-gold metal is expected to grow rapidly to build the batteries, motors, power cables and many other applications that will characterise modern energy infrastructure.
The International Energy Agency (IEA) has suggested world copper demand could double over the next 20 years as the pace of electrification grows, with clean energy applications potentially accounting for 45% of overall demand.
There are currently around 250 copper mines in operation in nearly 40 countries, with global production estimated by the US Geological Survey at 20 million tonnes in 2020 30% higher than it was just 10 years ago.
The countrys Cerro Verde and Antamina mines are among the worlds largest copper operations, while the Quellaveco mine being developed by Anglo American and Mitsubishi is expected to begin production in 2022, adding another substantial resource to Peruvian copper activities.
The country is perhaps better known as being the runaway leader among the worlds top cobalt producing countries and also home to by far the worlds largest cobalt reserves but copper mining often takes place alongside its cobalt operations and is a significant industry for the African nation.
The Kamoa-Kakula Copper Project, a joint venture led by Ivanhoe Mines and Zijin Mining, is a major copper mining asset currently under development in the DRC expected to add significant new potential to the countrys industry.
A major joint venture between BHP and Rio Tinto, known as Resolution Copper, is currently planned for Arizona that could become one of the countrys largest copper mines but there is currently uncertainty over the projects future due to a controversial land-swap deal opposed by Native American groups.

While construction and electrical grids have long been big markets for copper, today the rise in demand for electric vehicles, electric vehicle charging infrastructure and energy storage applications are considered some of the biggest drivers of copper consumption.
Given those factors, investors may want to keep an eye on the worlds top copper-producing companies. According to the latest stats from financial market data provider Refinitiv, the following top copper-producing companies produced the most copper in 2020.
The first top copper-producing company on the list is state-owned Codelco. As the worlds biggest copper producer, the company put out 1.76 million tonnes in 2020. Although there were concerns early in the year that operation curtailments due to the coronavirus pandemic would knock Codelco from its top spot, the Chilean company defied those expectations to meet its production guidance for the year.
In May 2021, Codelco announced the start of a US$1.4 billion project aimed at extending the life of its Salvador mine through 2068 by converting the underground mine to an open-pit operation. The project is a part of the companys 10 year, US$40 billion plan to upgrade its many aging mines.
Major diversified miner Glencore produced 1.26 million tonnes of copper in 2020. After suffering an 11 percent drop in copper production for the first half of the year versus the same period in 2019, the company cut its annual production guidance for the full year to 1.23 million tonnes.
Rather than COVID-19 disruptions, Glencore attributed its production declineto its Mutanda mine being placed on care and maintenance in 2019. Operations at Mutanda, the worlds biggest cobalt mine, are set to resume sometime in 2022. In addition to cobalt, the mine has five copper production lines.
In 2020, BHP produced 1.21 million tonnes of the red metal. The Australian mining giant managed to keep its copper production numbers high despite the years COVID-19 disruptions and strikes at Escondida, the worlds largest copper mine.
One of the companys biggest copper assets is the Grasberg mine in Indonesia, the 10th largest copper mine in the world. The company continues to make significant investments in Grasberg to increase both its copper and its gold production.
Canadas First Quantum Minerals produced more than 715,000 tonnes of copper in 2020. The company was able to increase its production guidance for the year despite temporary coronavirus shutdowns at its Cobre Panama mining operation.
Rio Tintos copper production in 2020 totaled 548,074 tonnes. The company is one of the largest diversified mining companies in the world behind BHP and like BHP, Rio Tinto was also negatively impacted by strikes at Chiles Escondida mine. Rio Tinto holds a 30 percent interest in the project.
Polands KGHM Polska Miedz has operations in Europe, North America and South America, and says that it holdsover 38 million tonnes of copper ore resources worldwide. In 2020, the company produced more than 543,000 tonnes of copper.
KGHM recently announced its cutting a few small assets from its portfolio, including the Carlotta copper mine in the US. In the first quarter of 2021, the company achieved its best operating and financial results in nearly a decade.
Chilean copper miner Antofagasta operates four mines in Chile and produced more than 503,000 tonnes of copper in 2020. The companys output was impacted by having to place its flagship Los Pelambres mine on care and maintenance, as well as by lower grades at its Antucoya operations.
Antofagasta recently pledged to cut its carbon emissions by 30 percent by 2025 by using renewable energy sources. By the end of 2020, the company reported that it was already powering 19 percent of its operations with renewable sources.
Moving forward, by 2030 Norilsk Nickel is looking to increase its copper production by 20 percent from its current level. The company is upgrading its production capacity at the Ruchey copper-nickel mine, replacing its obsolete Kola copper refinery with a state-of-the-art plant.
