Global Diamond Production

When we talk about global diamond production, we’re talking about the extraction of diamonds from various locations around the world. This production is carried out through both large-scale industrial mining operations and smaller-scale artisanal mining. 

When it comes to large-scale operations, companies begin by conducting geological surveys – including studying rock formations, taking soil samples, and utilising satellite imagery – to identify areas with potential diamond deposits, looking specifically for volcanic formations called ‘kimberlite’ and ‘lamproite pipes’. Once a site has been found, infrastructure development can begin. This involves two different kinds of mining operations – open-pit mining and underground mining. 

For open-pit mining, explosives are used to break up the rock and layers of soil are removed. Excavators and haul trucks then transport the ore to processing facilities, and ‘steps’ are cut into the sides of the pit to provide access. For underground mining, tunnels are constructed to reach deeper underground, using techniques such as ‘block caving’, which involves undermining a block of ore before it collapses and is collected.

For both operations, the ore is then transported to a processing plant where it is crushed into smaller pieces and searched for diamonds. Any recovered diamonds are then sorted based on their size, their shape, and their quality, with gem-quality diamonds separated from industrial diamonds. All gem-quality diamonds are then graded based on the 4C’s (carat, cut, color, and clarity) and their market value is determined. 

Russia’s Dominance

We touched briefly on ‘various locations’ when describing where diamonds are found, but actually, there are only a handful of common diamond locations around the world. These include Russia, Botswana, and Canada. 

When it comes to Russia, this country plays a dominant role in the global mining industry, being one of the top producers of diamonds by volume. ALSORA, the Russian mining company, is also one of the biggest in the world, operating multiple mines across Russia which produce millions of carats annually. With such a large production volume, Russia can exert substantial influence on global diamond prices and market trends, essentially asserting its dominance over the entire industry.

Botswana’s Rich Mines

Botswana also plays a significant role in the mining industry, with its rich diamond mines being a cornerstone of the country’s economy since their initial discovery in the late 1960s. Some of the most famous mines there include Jwaneng, which is one of the richest diamond mines in terms of value and volume. Over time it has even developed the nickname the ‘Prince of Mines’ due to its yield of high-quality, beautiful gem diamonds that are sold to jewellers at an exceptionally high price. The Orapa mine is another major diamond-producing operation, having been in operation since the early 1970s.

Canada’s Rising Role

Canada is the last of the ‘big three’ diamond locations, but its arrival into the fray was pretty late on, with the first major diamond deposits only founded in the early 1990s. This was when the mine known as ‘Ekati’ was discovered, with subsequent kimberlite exploration also unveiling the Diavik mine, which began production in 2003. In terms of job creation and revenue, these discoveries created thousands of jobs in the Northwest Territories, with Canada also becoming one of the most ethical and transparent countries when it came to diamond sourcing and supply chain management. 

Historical and Modern Mines

If you were to visit either Ekati or Diavik, you’d be looking at a quintessentially modern diamond mine, characterised by advanced technology, extensive infrastructure and, of course, stringent safety standards. But travel back a few hundred years, and you’d be looking at something quite different. 

Historical diamond miners had limited technology and equipment, which meant mining processes were largely labour-intensive, with basic extraction tools including picks, shovels, and sieves. In the 21st century, these tools have been replaced by automated machinery, remote sensing, 3D modelling, and real-time monitoring systems. 

Modern mines also operate under strict environmental regulations, aiming to minimise the negative ecological impact and promote sustainable practices throughout the mining process – sustainable practices that were completely non-existent just one hundred years ago!

Legacy of Golconda and Mirny

Still, there’s something quite striking about older mines like Golconda or Mirny. Located in India, Golconda has been a well-known diamond location for thousands of years, with the most iconic mine believed to be Kollur Mine, also known as the ‘Great Mine of Golconda’. Its legacy includes the incredible Koh-i-Noor, which means ‘Mountain of Light’ in Persian – a diamond with an illustrious history of ownership by various rulers and empires, including Indian, Persian and British monarchs. Mirny, on the other hand, was established in the 1950s and is renowned for its huge open-pit operation – a development which became one of the largest man-made excavations in the world.

Ekati and Diavik: Modern Marvels

That’s not to say modern mines are any less jaw-dropping. However, Ekati itself is located in the harsh Arctic terrain, with state-of-the-art equipment like autonomous haul trucks and large-scale excavators making it stand out as a technological marvel. Diavik, too, is located in a challenging sub-Arctic environment. One of the most remarkable things about this mine, though, is its innovative underwater mining operations. Using dikes and submersible pumps, diamonds beneath Lac de Gras – a 300 km glacial lake northeast of Yellowknife – are extracted in a lengthy process that involves creating underwater containment areas to facilitate their recovery. A feat that has since become a landmark achievement in the modern mining industry.

Technological Advancements in Mining

Keeping with Diavik for a second, one of the most amazing things about this mining location is that, despite the obvious challenges of extracting diamonds underwater, the latest technological advancements still make it possible to stick to a sustainable code. Remote monitoring systems, for instance, are used to undergo biological surveys and track whether there are any signs of environmental stress. 

Geomembrane liners are used to reinforce dikes and prevent seepage of water, settling tanks and modern filtration systems are used to purify the water extracted and discharge it back into the environment, effectively recycling the water used in the mining process. Elsewhere in the world, the mining company Debswana has implemented even more advanced technologies, including the use of X-ray sorting and dense media separation to improve the recovery rate and quality of diamonds while majorly reducing energy consumption. 

The diamond mine Gahcho Kue – a joint venture between De Beers and Mountain Province Diamonds – is also utilising an advanced environmental monitoring system, using it to track air quality, water quality, and the health of wildlife in the surrounding area. Around the world, the process of mining diamonds and keeping to regulatory requirements is only growing more efficient, to the point where modern mines – compared to historical mines – are almost unrecognisable in 2024.

Conclusion: Future of Diamond Mining

In terms of the future, things are only going to get more impressive. Continued advancements in mining technologies such as automation and remote sensing are going to continue improving operational efficiency and safety, with robotics also bound to reduce the need for human labour in dangerous environments – while also enhancing the precision and control needed throughout the mining process.

Sustainability is also going to be top of the priorities list, with new techniques to reduce carbon emissions and minimise the overall footprint of various mining activities. The rise in AI tech could also prove beneficial. Using AI-powered algorithms and machine learning techniques, geologists and exploration teams can pinpoint diamond deposits more easily, while the layout of mining operations and haulage routes can also be easily calculated. AI-enabled mining systems might also control and coordinate mining equipment without any human intervention, optimising the whole process to ensure it’s efficient, safe, and environmentally sustainable. 

As technology continues to evolve, the diamond mining industry will evolve along with it, becoming better and more sustainable in a way we can’t even yet imagine. And to think it all started with someone digging a big hole and finding something shiny. It’s amazing how far we’ve come!
