Ntughari

Nnụcha nke tantalum site na ores ya bụ otu n'ime usoro nkewa na-achọsi ike na metallurgy ụlọ ọrụ mmepụta ihe. Nsogbu bụ isi bụ na tantalum ores nwere nnukwu niobium, nke nwere kemịkalụ nke fọrọ nke nta ka ọ bụrụ nke Ta. E mepụtala ọtụtụ usoro iji dozie ihe ịma aka a.

N'oge a, a na-enweta nkewa site na hydrometallurgy. Mwepụta na-amalite site na iji hydrofluoric acid na-agbakọta ọla na sulfuric acid ma ọ bụ hydrochloric acid. Nzọụkwụ a na-enye ohere ka tantalum na niobium kewapụ iche na adịghị ọcha dị iche iche na-adịghị na nkume. Ọ bụ ezie na Ta na-apụta dị ka mineral dị iche iche, a na-egosipụta ya nke ọma dị ka pentoxide, ebe ọ bụ na ọtụtụ oxides nke tantalum (V) na-akpa àgwà n'otu aka ahụ n'okpuru ọnọdụ ndị a.

Niobium mmepụta

Mgbe nkewa si na mineral ndị ọzọ, a na-enweta oxides agwakọta nke tantalum Ta2O5 na niobium Nb2O5. 
A na-agbakwunye obere oxidizers dị ka sodium nitrate iji kwalite mmeghachi omume ahụ. Ihe si na ya pụta bụ aluminum oxide na ferroniobium, ihe nkedo nke ígwè na niobium eji eme ihe nchara. Ferroniobium nwere n'etiti 60 na 70% niobium. Na-enweghị ígwè oxide, a na-eji usoro aluminom mee ihe na-emepụta niobium. Ịdị ọcha ọzọ dị mkpa iji ruo ọkwa maka alloys superconductive. Igwe ọkụ eletrik na-agbaze n'okpuru oghere bụ usoro ndị isi abụọ na-ekesa niobium ji.
