ʻO Tantalum Niobium Ore Mine Concentrates

ka ʻO Tantalum Niobium Ore a umekaumaha kūʻai mākou:

Hana ʻia ʻo Tantalum

Kolika

ʻO ka hoʻomaʻemaʻe ʻana i ka tantalum mai kāna ores kekahi o nā kaʻina hana hoʻokaʻawale i koi ʻia i ka metallurgy ʻoihana. ʻO ka pilikia nui, ʻo ia ka nui o ka niobium i loko o nā ores tantalum, nona nā waiwai kemika aneane like me ko Ta. Nui nā kaʻina hana i kūkulu ʻia e hoʻoponopono i kēia pilikia.

I kēia manawa, loaʻa ka hoʻokaʻawale ʻana e ka hydrometallurgy. Hoʻomaka ka unuhi ʻana me ka hoʻolei ʻana i ka ʻaila me ka waika hydrofluoric me ka waikawa sulfuric a i ʻole ka waika hydrochloric. ʻO kēia kaʻina e hiki ai i ka tantalum a me ka niobium ke hoʻokaʻawale ʻia mai nā ʻano haumia ʻole i loko o ka pōhaku. ʻOiai ua loaʻa ʻo Ta ma ke ʻano he mau minela like ʻole, hiki ke hōʻike ʻia ma ke ʻano he pentoxide, no ka mea, ʻo ka hapa nui o nā oxides o tantalum(V) e hana like ana ma lalo o kēia mau kūlana.

Hana Niobium

Ma hope o ka hoʻokaʻawale ʻana mai nā minelala ʻē aʻe, loaʻa nā oxide hui ʻia o tantalum Ta2O5 a me niobium Nb2O5. 
Hoʻohui ʻia nā liʻiliʻi liʻiliʻi e like me ka sodium nitrate e hoʻomaikaʻi i ka hopena. ʻO ka hopena he alumini oxide a me ka ferroniobium, kahi hui o ka hao a me ka niobium i hoʻohana ʻia i ka hana kila. Aia ka Ferroniobium ma waena o 60 a me 70% niobium. Me ka ʻole o ka hao, hoʻohana ʻia ke kaʻina aluminothermic e hana i ka niobium. Pono ka hoʻomaʻemaʻe hou aʻe e hiki i ka pae no nā alloys superconductive. ʻO ka hoʻoheheʻe ʻana o ka beam electron ma lalo o ka vacuum ke ʻano i hoʻohana ʻia e nā mea hoʻolaha nui ʻelua o ka niobium.
