He aha nā hopena i ka ʻoihana honua maʻamau ma Kina,e like meka hoʻokaʻawale mana?

I kēia mau lā, ma lalo o ke kumu o ka lako mana paʻa, ua hoʻopuka ʻia nā leka he nui no ka palena o ka mana a puni ka ʻāina, a ua hoʻopilikia ʻia nā ʻoihana o nā metala maʻamau a me nā metala makamae i nā pae like ʻole. I loko o ka ʻoihana honua rare, ua lohe ʻia nā kiʻiʻoniʻoni liʻiliʻi. Ma Hunan a me Jiangsu, ua ho'ōki ka hana hoʻoheheʻe ʻana a me ka hoʻokaʻawale ʻana a me ka ʻōpala i nā ʻoihana, a ʻaʻole maopopo ka manawa no ka hoʻomau ʻana i ka hana. liʻiliʻi ka hana. Ke hana maʻamau nei ka hapa nui o nā ʻoihana honua ma Guangxi, Fujian, Jiangxi a me nā wahi ʻē aʻe. ʻO ka ʻoki ʻana i ka mana ma Inner Mongolia ua mau ʻekolu mahina, a ʻo ka manawa maʻamau o ka ʻoki ʻana i ka mana e pili ana i 20% o ka nui o nā hola hana. Ua ho'ōki kekahi mau mea hana magnetic liʻiliʻi i ka hana ʻana, ʻoiai ʻo ka hana ʻana o nā ʻoihana honua nui loa he mea maʻamau.

Ua pane aku nā hui i helu ʻia e pili ana i ka ʻoki mana:

Ua hōʻike ʻia ʻo Baotou Steel Co., Ltd. ma ke kahua pāʻani e like me nā koi o nā keʻena kūpono o ka ʻāina kūʻokoʻa, ua hoʻonohonoho ʻia ka mana palena a me nā hana liʻiliʻi no ka hui, akā ʻaʻole nui ka hopena. ʻO ka hapa nui o kāna mau mea eli ʻana he mau mea hana ʻaila, a ʻaʻohe hopena o ka ʻoki ʻana i ka mana i ka hana ʻana o ka honua.

Ua ʻōlelo pū ʻo Jinli Permanent Magnet ma ke kahua pāʻani he mea maʻamau ka hana a me ka hana ʻana o ka ʻoihana i kēia manawa, me ka lawa o nā kauoha i ka lima a me ka hoʻohana piha ʻana i ka mana hana. A hiki i kēia manawa, ʻaʻole i hoʻōki ka waihona hana Ganzhou o ka hui i ka hana ʻana a i ʻole ka hana palena ʻia ma muli o ka ʻoki ʻana i ka mana, a ʻaʻole i hoʻopilikia ʻia nā papahana Baotou a me Ningbo i ka ʻoki ʻana i ka mana, a ke holomua nei nā papahana e like me ka papa kuhikuhi.

Ma ka ʻaoʻao hoʻolako, ʻaʻole hiki ke komo i Kina nā mina rare earth ʻo Myanmar, a ʻaʻole maopopo ka manawa o ka ʻae ʻana i ka dute; I ka mākeke kūloko, ua hoʻomaka hou kekahi mau ʻoihana i hoʻōki i ka hana ʻana ma muli o nā mea nānā i ka mālama ʻana i ke kaiapuni, akā ke hōʻike nei ia i ka paʻakikī o ke kūʻai ʻana i nā mea maka. Eia kekahi, ʻo ka ʻoki ʻana i ka mana e piʻi aʻe nā kumukūʻai o nā mea kōkua like ʻole no ka hana ʻana o ka honua e like me nā waikawa a me nā alkalis, ka mea i hoʻopilikia ʻole i ka hana ʻana o nā ʻoihana a hoʻonui i nā pilikia o nā mea hoʻolako honua.

Ma ka ʻaoʻao koi, ua hoʻomau ka hoʻomaikaʻi ʻana o nā kauoha o nā ʻoihana magnetic hana kiʻekiʻe, ʻoiai ke koi ʻana o nā ʻoihana magnetic haʻahaʻa haʻahaʻa i hōʻike i nā hōʻailona o ka emi ʻana. He kiʻekiʻe ke kumukūʻai o nā mea maka, he mea paʻakikī ke hoʻouna i nā ʻoihana i lalo. Ke koho nei kekahi mau ʻoihana liʻiliʻi liʻiliʻi e hōʻemi i ka hana e hoʻokō i nā pilikia.

I kēia manawa, ʻoi aku ka paʻakikī o ka hoʻolako ʻana a me ka koi o ka mākeke honua, akā ʻoi aku ka ʻike o ke kaomi ma ka ʻaoʻao hoʻolako, a ʻo ke kūlana holoʻokoʻa ʻoi aku ka liʻiliʻi o ka hāʻawi ʻana ma mua o ka noi, he paʻakikī ke hoʻohuli i ka wā pōkole.

Ua nāwaliwali ke kālepa ʻana i ka mākeke honua i kēia lā, a ke piʻi mau nei nā kumukūʻai, ʻoi aku ka nui me nā honua ākea a me ke kaumaha e like me terbium, dysprosium, gadolinium a me holmium, aʻo nā huahana māmā māmā e like me ka praseodymium a me ka neodymium i ke ʻano paʻa. Ke manaʻo ʻia nei e piʻi mau ana nā kumukūʻai o ka honua i ka makahiki.

ʻO ke kumu kūʻai o ka praseodymium oxide i kēlā me kēia lā.

ʻO ke kumu kūʻai o ka terbium oxide i kēlā me kēia lā

ʻO ke kumu kūʻai o ka dysprosium oxide i kēia makahiki.
