The mining industry encompasses massive operations that extract valuable resources from the Earth’s crust, influencing global economies and industries. Let’s examine the ten largest mining operations worldwide, each showcasing human ingenuity and modern engineering prowess.

The Titans of the Mining World

Grasberg Gold and Copper Mine, Indonesia

Located in Papua, Indonesia, the Grasberg mine is a giant in the mining industry. Discovered in the 1930s, it began operations in 1972. It boasts the world’s largest known gold reserve and ranks among the top three for copper reserves globally.

From 1990 to 2019, Grasberg produced 53 million ounces of gold and 432 billion ounces of copper. Controlled by Freeport McMoRan, this mining operation is Indonesia’s largest taxpayer, highlighting its economic importance.

For investors interested in investing in mining stocks, operations like Grasberg exemplify the sector’s potential rewards and risks.

Escondida Copper Mine, Chile

In Chile’s Atacama Desert, at about 3,000 metres altitude, lies the Escondida copper mine. It’s the world’s leading copper producer, covering 17.7 kilometres north to south and 3.2 kilometres east to west.

In the first half of 2022, Escondida produced 824.4 kilotons of copper, accounting for 32% of global production. The mine is also investing $1.1 billion in renewable energy initiatives, aiming to reduce CO2 emissions by 3 million tons annually.

El Teniente Copper Mine, Chile

El Teniente, the world’s largest underground mine, is also in Chile. Its tunnels stretch over 3,000 kilometres, surpassing the distance from Sydney to Perth. This mine has been operational since 1819.

Recent developments at El Teniente include a project to produce an additional 50,000 tons of copper annually. The mine is also investing $5.4 billion in a new mine level project.

For those interested in understanding ore deposits, El Teniente provides an interesting case study in long-term mineral extraction.

Chuquicamata Copper Mine, Chile

Chuquicamata is the largest open-pit copper mine. It measures 975 metres deep, 2,900 metres wide, and 4,900 metres long.

This site’s mining history dates back to the Incan and Spanish colonial eras. A government-approved expansion plan from 2010 envisions the mine reaching 790 metres deeper by 2060, with daily ore production expected to reach 140,000 tons.

Diamonds Are Forever

Mir Diamond Mine, Russia

In Siberia, the Mir Diamond Mine has been operating since its discovery in 1955. During the 1960s, Mir produced 10 million carats of diamonds annually.

Now owned by Alrosa, the world’s largest diamond miner by volume, Mir employs 70% of the local population, demonstrating how mining operations can support remote communities.

Orapa Diamond Mine, Botswana

In Botswana, the Orapa Diamond Mine covers 121 hectares, making it the world’s largest diamond mine by area. Discovered in 1967, this joint venture between the Botswana Diamond Company and De Beers produces 10.8 million carats of diamonds annually.

Orapa operates seven days a week and contributes significantly to Botswana’s economy, funding investments in health, education, and infrastructure.

Iron, Lithium, and Gold: The Rest of the Best

Carajás Iron Mine, Brazil

The Carajás Iron Mine in Brazil was discovered accidentally in 1967 during manganese exploration. With an estimated 7.2 billion tons of iron ore, Carajás solidifies Brazil’s position as the world’s second-largest iron producer.

This site also contains significant deposits of manganese, tin, copper, aluminium, and gold. It’s currently owned by Brazilian mining company Vale.

Greenbushes Lithium Mine, Australia

In Western Australia, the Greenbushes Lithium Mine is the world’s largest lithium mine, producing 1.95 million tons of lithium annually.

Mining activities at Greenbushes date back to 1888, initially for tin. The discovery of lithium in 1980 changed its focus. Now jointly owned by Tianqi Lithium Industries of China (51%) and Albemarle Corp of the USA (49%), Greenbushes plays a key role in the global push towards renewable energy and electric transportation.

For investors examining the best mining stocks to buy, the lithium sector, exemplified by operations like Greenbushes, offers potential opportunities.

Muruntau Gold Mine, Uzbekistan

The Muruntau Gold Mine in Uzbekistan is an open-pit operation measuring 2.9 kilometres across and over 600 metres deep. In 2021, Muruntau produced 3 million ounces of gold.

Owned by the state-run Navoi Mining and Metallurgical Combinate, Muruntau is currently in its Stage 5 development phase.

Bingham Canyon Mine, USA

The Bingham Canyon Mine in the USA holds several world records, including being the largest artificial excavation site globally and the deepest open-pit mine at approximately 1.2 kilometres deep.

Bingham Canyon has produced more copper than any other mine in history – 17 million tons. It also produces significant amounts of gold, silver, and molybdenum. Owned by Rio Tinto and managed by Kennecott Utah Copper Co., Bingham Canyon represents large-scale, multi-mineral extraction operations.
