ʻO nā manaʻo kiʻekiʻe o ka mākeke, ka hilinaʻi i nā hui alakaʻi, a me nā hopohopo huna e pili ana i ke kūlana hoʻokele waiwai ua alakaʻi i kahi kūlana o ka makemake e ala, paʻakikī, makemake e hoʻi hope, a me ka makemake ʻole e hana pēlā ma ka mākeke honua i kēia pule (8.28-9.1). ).
ʻO ka mua, i ka hoʻomaka ʻana o ka pule, kahonua lahaUa hoʻomau ka mākeke i kona piʻi ʻana i ka hopena pule i hala.Ke alakaʻi ʻia e nā nīnau haʻahaʻa mai nā ʻoihana nui, hoʻomaka nā mea kanu hoʻokaʻawale a me nā ʻoihana kālepa e hoʻāʻo e alualu i nā quotations kiʻekiʻe.Ke alakaʻi ʻia e kahi liʻiliʻi o nā kauoha hoʻohui, ke kumukūʻai opraseodymium neodymium oxideua hoʻāʻo hou ʻia ma 505000 yuan / ton.Ma hope mai, hoʻomau ka piʻi ʻana o nā hale hana metala, a ʻike hou ʻia ka ʻōlelo o nā hale hana neodymium praseodymium e hoʻomaka ana mai 620000 yuan / ton.Me he mea lā ua hoʻomaka hou ka mākeke i ka pule i hala, i ka Pōʻalua, ua hoʻomaka nā hui kālepa e hoʻonui i kā lākou mau ukana a hāʻawi i nā uku.ʻO ka "pragmatic" wikiwiki o ka hoʻounaʻana i ukaliʻia, akā, ua kāohiʻia ka hoʻokaʻawaleʻana a me nā hale hana metala i ka hoʻokūpaʻaʻana i nā kumukūʻai, i alakaʻiʻia i ka emiʻana o ka hana o ka mākeke i kēia pule.ʻO nā ʻoihana o lalo ke kali-a-ʻike a makaʻala i ka wā e kali ana i ke kumukūʻai papa inoa o nā ʻāina laha ʻākau ma ka hopena o ka mahina.
ʻO ka lua, ma muli o ka hoʻokuʻu ʻia ʻana o ka manawa ma nā mines ma Myanmar a me nā kulekele hoʻomalu kaiapuni ma ka ʻāina ʻo Longnan, ua piʻi ka manaʻo no ka dysprosium a me ka terbium.I ka hoʻomaka ʻana o ka pule, ua alakaʻi ʻia e praseodymium a me neodymium, e alakaʻi ana i ka hoʻonui like ʻana o nā kumukūʻai a me nā kumukūʻai kālepa.Ma hope iho, ma muli o ke kūpaʻa o nā kālepa kumukūʻai kiʻekiʻe a me ka paʻakikī i ka loaʻa ʻana o nā kumu kūʻai haʻahaʻa o nā waiwai, a me ke kiʻekiʻe o ka quotation a me ke kāohi ʻana i nā hoʻouna mai nā mea kanu kaʻawale, ua hoʻokūpaʻa nā huahana dysprosium a me nā terbium a hoʻonui iki i nā kālepa.
ʻO ka hope, ke au ogadolinium, holmium, aerbiumUa ano kupua keia pule.Ke alakaʻi ʻia nei e nā huahana koʻikoʻi, ua hoʻomau nā kumukūʻai oxide o gadolinium, holmium, a me erbium, a ke manaʻoʻiʻo nei ka wehewehe ʻana i nā kulekele e lilo ka paʻa ʻana o nā kumukūʻai wahi i mea maʻamau no ka wā pōkole.No laila, ʻano wikiwiki ka piʻi ʻana o ke kumukūʻai, meerbium oxidepiʻi nui loa.Eia nō naʻe, ʻo nā nīnau no ka hao gadolinium a me ka hao holmium e hōʻike pū ana ʻaʻole i hoʻomaikaʻi maikaʻi ʻia nā kauoha no nā mea magnetic, e alakaʻi ana i nā hale hana metala e nānā mau ana i nā nīnau haʻahaʻa, kūʻai haʻahaʻa, a me nā hoʻouna kālā.
He manaʻo paʻakikī i ka iho ʻana a paʻakikī i ka piʻi ʻana.E hoʻomaka ana mai ka ʻauinalā o ka lā 17, me nā nīnau haʻahaʻa no ka dysprosium a me ka terbium mai nā hale hana mea magnetic kiʻekiʻe, ua kūpaʻa ka manaʻo o ka mākeke, a ua hahai nā mea kūʻai aku.ʻO ke kiʻekiʻe kiʻekiʻe o ka dysprosium a me ka terbium ua wela koke i ka mākeke.I ka hoʻomaka ʻana o kēia pule, ma hope o ke kumukūʻai kiʻekiʻe opraseodymium neodymium oxidea hiki i 504000 yuan/ton, ua hoʻi i ka 490000 yuan/ton ma muli o ke anuanu.ʻO ke ʻano o ka dysprosium a me ka terbium e like me ka praseodymium a me ka neodymium, akā ke ʻimi mau nei lākou a piʻi aʻe i nā kumu nūhou like ʻole, me ka paʻakikī o ka hoʻonui ʻana i ka noi.ʻO ka hopena, ʻo ke kumukūʻai o nā huahana dysprosium a me terbium i hoʻokumu i kahi kūlana kiʻekiʻe i kēia manawa ʻaʻole hiki ke haʻahaʻa, a ma muli o ka hilinaʻi ikaika i ka manaʻo o ka ʻoihana i ke gula, ke kālā, a me ka ʻumi, ʻaʻole lākou makemake e kūʻai aku, e ulu nui ana. ʻike ʻia i ka wā pōkole.
Ke nānā nei i hope i kēia pule, aia nā hiʻohiʻona penei:
1. ʻO ke kumu kūʻai o ka praseodymium a me ka neodymium he mea paʻa a ikaika, e paʻakikī ke kālepa ma nā kumukūʻai haʻahaʻa.ʻO ke kūpaʻa o ke kumu kūʻai mua he mea maopopo.
2. I ka hoʻomaka ʻana o ka pule, ʻoi aku ka ʻike o ke ʻano o ka huki ʻana, ka nānā ʻana i ka waena o ka pule, a me ka ʻimi hou ʻana i ka hopena pule, akā ʻo nā nīnau haʻahaʻa a me nā kumukūʻai haʻahaʻa ke ʻano nui.
3. Loaʻa i nā kauoha nui nā mea hoʻokalakupua i lalo i ke kumu kūʻai, ka nui, a me ka manawa kūʻai.
4. Ke emi mālie nei ke kūlana hoʻohuli i mua o ke kaulahao ʻoihana: ʻoi aku ka ikaika o nā hale hana e hoʻokaʻawale i ka ʻōpala i ka hoʻēmi kumu kūʻai a me ka hoʻomākaukau ʻana i ke kūʻai;Ma waena o ka piʻi ʻana a paʻa o nā kumukūʻai oka maka, ua makaʻala nā ʻoihana hoʻokaʻawale maka i ka eli a me ka hoʻopiha ʻana;Hāʻawi nā hale hana metala i nā kumukūʻai nopraseodymium neodymiumahao dysprosiume hoʻopaʻa i ke kula kiʻekiʻe a e hoʻohaʻahaʻa i ka hoʻohuli kālā;Ua hoʻonui iki nā ʻoihana mea magnet i kā lākou mau ʻōlelo i nā kauoha ʻōkeke a me nā kauoha hou no ke kila magnetic.ʻOiaʻiʻo, ʻo ka manaʻo o ka hoʻololi ʻana i ka manawa no ke kumukūʻai e hōʻoluʻolu i nā hangovers e paʻa nui ʻia ma nā ʻaoʻao āpau o ke kaulahao ʻoihana.
5. ʻO ka ʻaoʻao nūhou ke kumu nui o ka manaʻo mākeke no ka wā pōkole.ʻO Dysprosium a me terbium ka mea i hoʻopilikia nui ʻia e ka nūhou i kēia pule, me ka piʻi wikiwiki ʻana o nā kumukūʻai.
6. ʻO ka manaʻo noʻonoʻo o gadolinium, holmium, a me ka erbium he mea hōʻike nui, me ka hoʻolako ʻana i nā waiwai a me ka piʻi iki o nā kumukūʻai kālepa.Ke noi ikaika nei nā ʻoihana kālepa e pili ana i nā kauoha, akā ʻilihune mau ka lawe ʻana i lalo.
Ma kēia Pōʻalima, nā kumukūʻai o nā ʻano huahana like ʻole: 498000 a 503000 yuan / ton opraseodymium neodymium oxide; Metal praseodymium neodymium610000 yuan/ton;Neodymium oxidehe 505-501000 yuan/ton, a me ke kilaneodymiumhe 62-630000 yuan/ton;Dysprosium oxide 2.49-2.51 miliona yuan/ton;2.4-2.43 miliona yuan/ton ohao dysprosium;8.05-8.15 miliona yuan/ton oterbium oxide; Terbium metala10-10.2 miliona yuan/ton;298-30200 yuan/ton ogadolinium oxide;280000 a 290000 yuan/ton ohao gadolinium;62-630000 yuan/ton oholmium oxide; hao Holmiumkoina 63-635 tausani yuan/ton.
Ma ke ʻano holoʻokoʻa, ua maʻalahi ke ʻano o kēia manawa no ka hoʻouna ʻana i ka praseodymium neodymium, a ua koʻikoʻi ke kaomi ʻana i ka ʻai maka a me nā ʻōpala.I loko o nā mahina ʻelua o ka hoʻohaʻahaʻa ʻana i ke ʻano piʻi, ʻaʻole lawa ka waihona ma nā kihi a pau o ke kaulahao ʻoihana.Malia paha, i ka wā e hiki mai ana, ʻoiai e hoʻomau ʻia ka manaʻo o ka mākeke e nā mea kūʻai aku, e hoʻi hou ana i nā mea kūʻai aku.Mai kahi hiʻohiʻona macro, ke hele nei kahi pōʻai hou o nā kulekele hoʻoulu, a ʻo Sepatemaba ka puka aniani nui no ka hoʻokō ʻana i nā kulekele, inā paha nā kulekele waiwai a i ʻole nā kulekele hōʻaiʻē.Mai kahi hiʻohiʻona microscopic, e nānā ana i nā loli hou o praseodymium a me neodymium, ke emi mau nei ka emi ʻana o nā oxides, a ua ʻoi aku ka nui o ka ikehu kinetic spiral.No ka hoʻokolokolo e hiki mai ana, ʻoiai ʻoi aku ka nui o ka praseodymium neodymium i ka mākeke i hoʻohālikelike ʻia i ka dysprosium a me ka terbium, e hōʻike ana nā ʻoihana alakaʻi i ko lākou ʻano alakaʻi, a e hoʻomau nā kumukūʻai upstream e hoʻomau a piʻi hou aʻe.No nā honua liʻiliʻi a koʻikoʻi e like me dysprosium a me terbium, e pili ana i nā hiʻohiʻona o kēia manawa a me nā nūhou, aia nō kahi wahi no ka ulu ʻana.
