Tantalum Ore a natural mineral formation containing tantalum in compounds and quantities that make its industrial extraction technically feasible and economically expedient. A distinction is made between tantalum ores proper, in which Ta2O5:Nb2O5 ≥ 1, and complex tantalum-niobium ores. The main minerals of tantalum ores are columbite-tantalite ...
Niobium metal appears next to tantalum in the periodic table as it has similar chemical properties. Niobium ore is more abundant in its raw state and is less expensive. This has given the opportunity for tantalum capacitor manufacturers to evaluate niobium as a potential alternative to tantalum metal; however there were two key
There is now an alternative to solid tantalum capacitors. ... The selection of tantalum capacitors is not always limited to electrical performance, but can also be also affected by ethical and commercial issues.

price of tantalum powder fluctuates sharply as the production volume of tantalum is limited. For instance, in the year 2000, the demand for tantalum increased, and the price of tantalum ore increased to six times that in 1999. As a result, capacitor manufacturers encountered a material crisis in the supply of tantalum.
tantalum ore on this earth, and surely we must be running out of reserves. Tantalum ranks as 53rd of the elements in abundance on this earth. True, there is a limited amount of ore, but with present day usage, and pro-jecting a growth rate of usage of 18%, there is enough ore being mined today to satisfy the world demands for the next 50 years.
Tantalite is the most widespread tantalum mineral and makes for an important ore of the industrially useful metal. Tantalum is used in alloys for strength and higher melting points, in glass to increase the index of refraction, and in surgical steel, as it is non-reactive and non-irritating to body tissues.
The probable ore reserves at Bald Hill mine are estimated at 11.3Mt of lithium ore and 2Mt of tantalum ore. The mine is estimated to contain 114,100t of Li 2 O and 1.4Mlb of Ta 2 O 5. Mining at Bald Hill mine. The Bald Hill lithium and tantalum mine is being developed in two phases, with the first phase focused on starting lithium production.
