However, with HF conditioning at pH 6 or above, ore-mineral flotation was enhanced. This is seen in the recovery-pH plot for the four ore minerals by comparing figure 6 with figure 4. Sodium isooctyl phosphate was investigated as a collector for columbium-tantalum ore minerals because of promise shown in contact-angle tests.

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.

This led the OECD, U.S., and EU to name tantalum a "conflict mineral" and pass regulations to improve its traceability. Among them are the U.S. Dodd-Frank Act of 2010 and the upcoming EU Conflict Minerals law. Despite these rules, no one had a foolproof way to prove where tantalum actually came from. Until now.
