4 Top Tantalum-mining Countries

The DRC was the epicenter for tantalum mining in 2016. Find out which other three countries produced significant amounts of the metal last year.

Tantalum is an important component in many modern technologies, and is used in capacitors for everything from computers to mobile phones.

Despite its importance in the world today, tantalum mining takes place in very few countries. Only four countries produced tantalum in 2016, and most was mined in the Democratic Republic of Congo (DRC), an area known for issues related to conflict minerals.

Rwanda, Brazil and China were the other top countries for tantalum mining last year. Read on to learn more about the world’s largest producers of the metal; all statistics come from the US Geological Survey’s most recent report on tantalum.

1. DRC

Mine production: 450 MT

Rwanda took the top spot for tantalum mining in 2015, but in 2016 the DRC took the lead again, producing about 40 percent of the world’s tantalum. In total, it put out 450 metric tons (MT) last year.

As mentioned, mining practises in the DRC have a reputation for being being corrupt. Steps have been taken to discourage companies from purchasing tantalum produced unethically in the country, but they have faced challenges. For instance, the Dodd-Frank Wall Street Reform and Consumer Protection Act, which was designed in part to stop the flow of conflict minerals from countries like the DRC, has been slow to have an impact on buyers of conflict minerals. Recently, the Trump administration voiced a desire to repeal some parts of the act.

2. Rwanda

Mine production: 300 MT

Rwanda is one of the world’s biggest tantalum producers, but like the DRC its standing is fraught with controversy — it is an open secret that much of Rwanda’s mineral production arrives from countries like the DRC, where conflict minerals are an issue. 

For that reason, it is difficult to ascertain how much tantalum is actually produced by Rwandan mines. Better Sourcing is one company aiming to make the Rwandan mining industry more transparent.

3. Brazil

Mine production: 115 MT

Brazil is the largest tantalum-producing country outside of Africa. Overall, Brazil is home to 36,000 MT of tantalum reserves.

The country’s largest tantalum mine is the MIBRA project, owned by Advanced Metallurgical Group (AMS:AMG). In light of issues facing tantalum from Rwandan and Congolese suppliers, Brazil could become a major source of tantalum for companies around the world in the coming years. In 2016, the country was the largest supplier of tantalum minerals to the US, accounting for 38 percent of imports.

4. China

Mine production: 60 MT

China is a major tantalum producer and is the biggest supplier of tantalum metal to US companies. Almost 37 percent of the tantalum metal exported to the US comes from China, according to the US Geological Survey, and the country’s production has held steady year-over-year.

  • This data is incorrect. CY 2015 shipments of tantalum ore from Congo and DRC is 600 Metric Tons. Shipments from Rwanda are 1046 metric tons. Africa and the rest of the world have done a remarkable job in regulating the supply of tantalum ore and have been subjected to intense scrutiny because of an amendment to sweeping United States financial legislation. A key player and I were having drinks when the theft of tantalite broke out of dar el Saleem and the immediately reaction was- oh those thieve dont know what they are doing; they are stealing a base metal that is under microscopic scrutiny; every cop and public official from here to Shanghai is going to be on the look out for it. Anyway, shipment data for ore is specific and the methodology to gather it, which I developed 20 years ago, is exceptionally accurate. I may suggest to the TIC that I present the methodology, a lot of which was based upon the on site surveys of actual mine sites by Sons of Gwalia.
