Nowemapa 5th, 2021 i ka 81st auction, ua pau nā hana a pau ma 930000 yuan / ton no PrNd, a ua hōʻike ʻia ke kumukūʻai alarm no ke kolu o ka manawa.
I kēia mau lā, ua kū ke kumu kūʻai o ka honua i kahi kiʻekiʻe loa, e huki ana i ka nānā ʻana i ka mākeke. Mai ʻOkakopa, ua hōʻike ʻia ke kumukūʻai o ka honua i kahi piʻi aʻe. Ua hoʻonui ʻia ke kumukūʻai o Praseodymium a me Neodymium oxide mai 598000 yuan / ton i ka hoʻomaka ʻana o ʻOkakopa i 735000 yuan / ton ma ʻOkakopa 28, he piʻi o 22.91%.
Ua piʻi nui nā kumukūʻai o ka honua laʻa i nā pule ʻelua i hala iho nei, ʻoi aku ka nui o ke kumukūʻai o nā huahana rare earth māmā. ʻO ka ʻoiaʻiʻo, aia kahi kāhea kiʻekiʻe ma ka mākeke honua rare i ka Pōʻalima i hala. Wahi a kēia hoʻoholo, ʻoi aku ka hopena o kēia pōʻai o ka mākeke honua i ka manaʻo o ka mākeke. ʻO ke kumu, ʻo ka manaʻo o ka mākeke mai ka panic o ka palena o ka mana, ka laka a me ke kūʻai ʻole ʻana i nā waiwai ma ka hopena paʻa, a me ka hoʻopaʻa mau ʻana i ka hopena o ka lako. Ua ʻōlelo kekahi poʻe loiloi e hiki ke hoʻomau i ke kiʻekiʻe o nā kumukūʻai o ka honua i ka wā e hiki mai ana.
Paʻa ka hoʻolako ʻana i nā ʻāina laha ʻole ma Kina, a hoʻopaʻa ka poʻe paʻa i nā waiwai a makemake ʻole e kūʻai aku. No kekahi manawa, loaʻa i nā ʻoihana i luna nā manaʻolana kiʻekiʻe no nā kumu kūʻai o ka honua, ʻo ia ka mea i loaʻa ʻole nā mea kūʻai i kēia manawa. ʻOiaʻiʻo, ma muli o ka hemahema o ka lako, ʻuʻuku loa ka wahi. I kēia manawa, ʻo nā ʻoihana e laka a kūʻai aku i nā waiwai mai Sichuan, Fujian, Jiangxi a me Inner Mongolia.
I ka ʻike ʻana o ka ʻoihana, ke piʻi mau nei ke kumukūʻai o ka metala Praseodymium a me Neodymium, a me ka hoʻomau mau ʻana i ke kumukūʻai kūʻai kiʻekiʻe o ka makahiki, ʻo ia ka mea ma muli o ke koi ikaika o lalo, ka hoʻemi ʻana o ka mana a me ka hana ʻana o nā mea kanu metala. a me ka ho'ēmi 'ana o ka oxide o nā mea kanu ho'oka'awale, 'o ia ho'i ka lawa 'ole o ka waihona waiwai maka a me ka loa'a 'ana o nā wahi pa'a.
Eia naʻe, ke hoʻomau nei ka hemahema o ka lako honua. Hoʻopaʻa ʻia ka lawe ʻana mai o nā minerala o Myanmar, paʻa ka hoʻolako ʻana i nā minerala honua laha ʻole, paʻa pū ka hoʻolako ʻana i nā mea ʻōpala, a ikaika ke kumukūʻai, e pili ana i ke kumu kūʻai i lalo o Praseodymium a me Neodymium oxide. Eia kekahi, ke piʻi aʻe nei nā kumukūʻai o nā mea kōkua, a ua hoʻonui ʻia nā kumukūʻai o nā ʻoihana hoʻokaʻawale. Eia kekahi, ua hōʻemi kekahi mau ʻoihana hoʻokaʻawale ma Jiangxi, Jiangsu, Zhejiang, Hunan a me nā wahi ʻē aʻe i ka hana ʻana, e hopena i ka hemahema o Praseodymium a me Neodymium oxide wahi lako. Me ka hiki ʻana mai o ka pōʻai kūʻai o nā ʻoihana waiwai magnetic, ua hoʻomau ke kumukūʻai o Praseodymium a me Neodymium i kēia manawa.
No laila, e ʻae paha nā ʻoihana waena a me lalo i ka piʻi mau ʻana o nā kumukūʻai o ka honua? ʻO nā hale hana mea magnetic nui ka nānā nui ʻana i nā kauoha lōʻihi. ʻO ka mea maʻamau, ʻo ka lōʻihi lōʻihi he manawa makahiki hoʻokahi a me ka hapa makahiki, hiki ke pale i ka pilikia o ka piʻi ʻana o ke kumukūʻai wahi i kekahi ʻano, akā i ka wā lōʻihi, ʻaʻole hiki ke hoʻopilikia ʻia. Eia kekahi laʻana, kekahihale hana mea magneticua hoʻohuli i ke kumukūʻai a me ke kumukūʻai i nā degere like ʻole i kekahi manawa i hala.
Mai ʻAukake a Kepakemapa o kēia makahiki, aia ke kumukūʻai o ka metala PrNd ma kahi kiʻekiʻe o 700000 yuan / ton - 750000 yuan / ton, kahi i kāohi ai i ka hoʻohana ʻana i kekahi mau mea waena a haʻahaʻa.Neodymium-Iron-Boron magnet, akā ua wikiwiki ka komo ʻana o nā huahana kiʻekiʻe i ka ʻoihana kaʻa kaʻa hou. I ka manawa like, i alakaʻi ʻia e ka nele o ka mana a me ka mana ʻelua o ka ikaika o ka ikehu, ua hoʻololi koke nā ʻenehana ʻoihana i nā kaʻa NdFeB. ʻOiai ua hōʻemi ka hopena holoʻokoʻa ma muli o ka waena a me ka haʻahaʻa haʻahaʻa NdFeB magnets, ka piʻi ʻana o ka hapa onā mākēneki Neodymium kiʻekiʻeke kākoʻo nei hoʻi i ka ulu ʻana o ka nui o ka noi no nā ʻāina laha ʻole. Ke kākoʻo mau nei ka mākeke i ke kumukūʻai o Praseodymium a me Neodymium. Ma lalo o ke kua o ka ulu wikiwiki o ka puka onā kaʻa ikehu houa me ka hiki i hookomoia onā motika makani, ke hoʻomau nei ka hoʻomaikaʻi ʻana o ka noi no nā magnet NdFeB, a paʻakikī ke kumukūʻai kiʻekiʻe o Praseodymium a me Neodymium e hāʻule a hoʻomau i ka hoʻomaikaʻi.
