Tantalum is a rare mineral essential for making capacitors for devices like smartphones and laptops. A small region of Africa produces 60% of the world's supply, with Rwanda as the main exporter. But tantalum was sometimes smuggled in from conflict-ridden Congo, where it was mined by children or workers enslaved by warlords.
Here is a method to recover tantalum from scrap capacitors.I am working on it but I had a little accident last time:I melted the hole caps and the black ones (Motorola) exploded!!!!! so I need to crush them before melting.As soon as I develope this method I promess to post it,step by step.

Refining - Tantalum. Tantalum. Pure tantalum is not found naturally. Tantalum i. . s obtained commercially by first creating tantalum oxide (TaO 5). The tin industry also produces tantalum as a by product from smelting cassiterite ore concentrates for processing. The biggest tantalum mine is the Mibra operation in Nazareno, Brazil.
Apr 24, 2017· Tantalum comes from the processing and refining of tantalite Tantalite is the common name for any mineral ore containing tantalum Most tantalum mines are open pit; some are underground The process of mining tantalum involves blasting, crushing and transporting the resulting ore to begin the process of freeing the tantalum.

Tantalum Impact on Opal Mining. Some experts suggest that tantalum mining can severely throttle the future supply of Welo opal. Tantalum mining has previously shut down gemstone production in other countries. Marropino morganite is one such gem. In 2010, morganite mining operations ceased in favor of the more valuable tantalum.
Prior to the shift, Australia & Brazil were the major tantalum mining countries. Beginning in 2007, the DRC, Rwanda, and other African countries became the major sources of tantalum production. The production shift from Australia was a result of high extraction costs and an unfavorable exchange rate, which meant that mining tantalum ore in ...
Tantalum alloys that have good high temperature strength are used in many aerospace products. However, all tantalum alloys oxidize rapidly and surface coatings are required for elevated temperature service in oxidizing environments. Tantalum and niobium alloy with each other and with nickel, cobalt, chromium, tungsten and many other elements.

I had a bunch of them on boards, they didn't have the density I would expect from tantalum so I didn't pull them. Thanks though, as I was clueless as to what type they were, and there is not a good depository online, beyond what is here. I get most confused by the wet type of tantalum caps.

Canadian tantalum reserves are est imated to contain more than 3,000 t of contained tantalum. U.S. tantalum resources are of low grade, and none were considered economically minable in 1998. PRODUCTION AND PRODUCTION PROCESSES The United States, which has no tantalum mining industry, must import all its tantalum source materials for processing.
Non-lithium rights, including tantalum, for the deposit are held by GAM. Reports by Talison Lithium indicate that tantalum mining began in 1992 with an ore processing capacity of 800 ktpa 33. Initial mining was from the Cornwall open pit, moving underground in the early 2000s. Plant capacity was upgraded in the late 1990s to 4 Mtpa.

Tantalum ore is composed of both tantalum and non-tantalum containing minerals, and the Ta 2 O 5-equivalent content is typically 0.02–0.04 percent. Low-grade tantalum ore is physically concentrated (beneficiation) to a concentrate of 20–40 percent Ta 2 O 5 -equivalent at the mining site before sale to smelters ( Linnen et al., 2014 ).
