Volvo publishes list of 5 most impressive mines around the world

According to the latest figures, the total revenue of the top mining companies worldwide was US$496 billion. With different mineral deposits located all over the globe the mining sector operates in extreme and remote environments. Swedish vehicle manufacturer Volvo recently published a list of the most impressive mines around the world.

1.  Kalgoorlie Super Pit, Australia

Located in Western Australia, the Kalgoorlie Super Pit is one of the largest open pit gold mines in the country. At 600 m deep, 3.5 km long and 1.5 km wide – it can even be seen from space. Originally a series of underground mines, the Super Pit was created in 1989 by Kalgoorlie Consolidated Gold Mines. Every year 15 million t of rock are moved using conventional drills wheel loaders and haulers. From this ore, 23 000 kg of gold is extracted every year – this adds up to a whopping AUS$980 million. The mine also contributes over AUS$300 million to the local economy every year.

2. Carajás Mine, Brazil

The world’s largest iron ore mine is located in the state of Para in Northern Brazil. Carajás Mine is thought to hold 7.2 billion t of iron ore in reserves. In 2007, US$2.48 billion was invested in an expansion project. The project took three years to complete and added 30 million t to the mine’s yearly capacity. Brazil has historically been one of the world’s largest exporters of iron ore. According to the latest figures, Australia is now responsible for over half of all iron ore exports by value. Latin America, excluding Mexico, and Caribbean countries account for one fifth.

3. Diavik Mine, Canada

The Diavik Mine is the world’s most distinguished diamond mine, producing over 100 million carats of diamonds since operations started in 2003. Located in a northern province of Canada, the mine is just 220 km south of the Arctic Circle. Between 2000 and 2003, approximately CAN$1 billion was spent building the mine’s infrastructure – one of the largest capital investments undertaken in the history of Canadian mining. In 2015 the Diavik Foxfire was discovered, weighing in at 187.63 carats, the two-billion-year-old stone is the largest known diamond ever to be discovered in North America.

4. Mponeng gold mine, South Africa

Located in South Africa’s Gauteng province, the Mponeng gold mine is the deepest on earth – descending almost 4 kilometers. Temperatures this close to the earth’s core can reach 60°C. But to ensure workers are kept safe, a series of five meter wide fans blow ice slurry into the mine. The mine is made up of around 400 km of tunnels – that’s longer than the New York subway. Approximately 4000 workers descend into these tunnels every day by elevator. The 2.5 mile trip takes over 90 minutes. Everyday, nearly 3000 kg of explosives are used to excavate 6400 t of rock. Sometimes these processes result in seismic activity, which can trigger around 600 earthquakes a month. Miners are kept alert to these dangers by seismic monitoring stations.

5. Nazlet Sabaha

Machinery has revolutionised the way we mine. Our modern technology has made such huge leaps in our mining productivity that we can now move 100 t of material in one go. But thousands of years ago miners didn’t have Volvo’s Rigid Hauler R100E to help with their workload. The most ancient mines in the world are thought to be 50 000 years old and can be found on the western banks of the River Nile. Here, they mined chert – a hard sedimentary rock that was used for tool-making and to strike sparks for fire. Although these mines are no longer in operation they highlight that the ingenuity of humankind began thousands of years ago.
