Nā ʻano hana metallurgical rare earth

ʻElua mau ala maʻamau o ka metallurgy honua laha, ʻo ia ka hydrometallurgy a me ka pyrometallurgy.

Aia ka Hydrometallurgy i ke ʻano metallurgy chemical, a ʻo ke kaʻina holoʻokoʻa ka hapa nui i ka hopena a me ka solvent. No ka laʻana, ka decomposition o ka laha 'ole o ka honua concentrates, kaawale a me ka unuhi onā ʻokikene honua laha ʻole, nā pūhui, a me nā metala honua laha ʻole e hoʻohana i nā kaʻina hana hoʻokaʻawale kemika e like me ka ua, crystallization, oxidation-reduction, solvent extraction, a me ka hoʻololi ion. ʻO ke ʻano maʻamau i hoʻohana ʻia, ʻo ia ka hoʻoheheʻe ʻana i nā mea hoʻoheheʻe organik, kahi kaʻina holoʻokoʻa no ka hoʻokaʻawale ʻana i ka ʻoihana o nā mea hoʻokahi maʻemaʻe kiʻekiʻe. He paʻakikī ka hana hydrometallurgical, a he kiʻekiʻe ka maʻemaʻe o ka huahana. Loaʻa i kēia ʻano hana ka nui o nā noi i ka hana ʻana i nā huahana i hoʻopau ʻia.

He maʻalahi ke kaʻina hana pyrometallurgical a he kiʻekiʻe ka huahana.honua laha oleʻO ka pyrometallurgy ka mea nui o ka hoʻomākaukau ʻana i nā mea hoʻoheheʻe honua maʻamau e ka hoʻemi silicothermic, nā metala honua ʻole a i ʻole nā ​​​​mea hoʻoheheʻe ʻia e ka paʻakai hoʻoheheʻe electrolysis, a me nā mea hoʻohui honua e ka hoʻemi ʻana i ka wela. ʻO ke ʻano maʻamau o ka pyrometallurgy ka hana ʻana ma lalo o nā kūlana wela kiʻekiʻe.
