tantalite tantalite occurs in granitic pegmatites that are rich in rareearth elements, and in placer deposits derived from such rocks. it has been found in australia, brazil, canada, colombia (guainía and vichada), egypt, northern europe, madagascar, namibia, nigeria, rwanda, the democratic republic of congo, the united states (california, colorado, maine, and ia), and zimbabwe. dark black,

much of rwandas mineral production arrives from countries like the drc, where conflict minerals are a problem. for that reason, it is difficult to know how much tantalum is actually produced by rwandan mines. better sourcing is one company aiming to make therwandan tantalum mining industry more transparent. in 2018, it was reported that a macedonian company, power resource group, had made a $12million investment in land towards the construction of atantalum refineryin rwanda. once complete it will be the countrys only mineral refinery. see full list on investingnews.com mine production: 370 mt the drc and rwanda switched places for tantalum mining in 2017. the drc wound up in second place last year, producing roughly 30 percent of the worlds tantalum. in total, it put out 370 mt for the period. 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 doddfrank 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 beenslow to have an impact. whats more, once in power the trump administration voiced a desire torepeal some parts of the act. later on, the senate approved plans to roll back many of the key rules in the act, essentiallyrendering it defective. in 2018, the house approved a rollback bill, and trump signed it into law. see full list on investingnews.com mine production: 190 mt

country, and one of only two on the list outside of africa. overall, brazil is home to 34,000 mt of tantalum reserves. the countrys 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 2017, the country was the largest supplier of tantalum minerals to the us, accounting for 40 percent of imports. see full list on investingnews.com mine production: 95 mt china is another large tantalum producer, and in 2017 its production held steady yearoveryear, increasing just 1 mt. last year, it was the biggest supplier of tantalum metal to us companies, with 23 percent of the metal imported to the us having come from china, according to the us geological survey. that number may be quite different in 2018, after the two countries engaged in a trade warinvolving high tariffs for both sides. see full list on investingnews.com while australia did not make the top tantalummining list last year, its expected that it will appear on it in 2018. the country has the largest
