Another reason is the environmental requirements and economic challenges in extracting tantalum from tin slag are also negative [58]. 3.3 Lithium ore Tantalum has historically been an important by-product of lithium-making processes [67]. The tantalum can be recovered from polymetallic lithium ores during beneficiation [68].

Impure tantalum was isolated in 1825 by Swiss chemist Jean-Charles-Galissard de Marignac and, in purer form, by Heinrich Rose in 1844. It is found, in combination with its congener niobium, in tantalite/columbite (Fe, Mn)(Ta, Nb) 2 O 6 ore, with tantalite containing more tantalum than niobium. Its crustal abundance is 1.7 parts per million ...
