Kaolin he mineral ʻaʻohe metala, he ʻano lepo a me ka pōhaku lepo i haku nui ʻia meHe mau minelala lepo Kaolinite. No ka mea, he keʻokeʻo a palupalu hoʻi, ua kapa ʻia hoʻi ʻo ia he lepo Dolomitic. Ua kapa ʻia ʻo ia ma hope o ke kauhale ʻo Gaoling, Jingdezhen, Jiangxi Province. He keʻokeʻo, palupalu, palupalu a lepo kona Kaolin maʻemaʻe, a he mau waiwai kino a me kemika maikaʻi e like me ka plasticity a me ke kū'ē ʻana i ke ahi. ʻO kona ʻano minelala, ʻo ia ka Kaolinite, Halloysite, Hydromica, Illite, Montmorillonite, Quartz, Feldspar a me nā minelala ʻē aʻe.

He mineral lepo maʻamau a koʻikoʻi loa ʻo Kaolin ma ke ʻano. Hoʻokumu ʻia ia e ka palaho ʻana o ka feldspar a i ʻole nā ​​​​minelala silicate ʻē aʻe i loko o nā pōhaku igneous a me metamorphic i loko o nā media acidic nele i nā metala alkali a me nā metala alkaline honua.

Ua uhi ʻia ka lepo Kaolin me kahi mea hoʻopili, a pēlā aku, e hoʻonui i ka nui o ka lepo Kaolin i hoʻohui ʻia i loko o ka laholio palakiko, a hoʻohana ʻia e mālama i nā mea hoʻopihapiha lepo Kaolin no nā palakiko laholio.

I waena o lākou, ʻo ka hoʻokaʻawale magnetic kahi ʻano hoʻokaʻawale mineral kino i hoʻohana nui ʻia ma ke kahua o ka hana mineral. ʻO kona kumu nui ka hoʻohana ʻana i nā ʻokoʻa magnetic o nā mineral ponoʻī e hoʻokō i ka hoʻokaʻawale ʻana. Wahi a nā waiwai magnetized o nā mineral, hiki ke hoʻokaʻawale ʻia ka hoʻokaʻawale magnetic i ka hoʻokaʻawale magnetic ikaika, ka hoʻokaʻawale magnetic nāwaliwali, ka hoʻokaʻawale magnetic hoʻohuli a me ka hoʻokaʻawale magnetic gradient kiʻekiʻe e hoʻokō i nā pono o nā mineral like ʻole. ʻO nā lako hana mineral e pili ana i nā mea hoʻokaʻawale magnetic plate, nā mea hoʻokaʻawale magnetic gradient kiʻekiʻe apo vertical, nā mea hoʻokaʻawale magnetic gradient kiʻekiʻe slurry electromagnetic, nā mea hoʻokaʻawale magnetic superconducting haʻahaʻa wela, a pēlā aku.

05 Nā hihia noi hana mineral

Kaʻina Hana 1: Ma ka lawe ʻana i kahi lepo Kaolin haole ma ke ʻano he laʻana, ʻo nā mea haumia nui i loko o kēia laʻana e komo pū ana me ka hao oxide, titanium oxide, a me ka silicate hao. I loko o ka ore maka, ʻo ka nui o nā mea haumia o Fe2O3 a me TiO2 he 0.89% a me 0.17% pakahi, ʻoiai ke keʻokeʻo e hiki i ka 67.29%.

I mea e wehe pono ai i kēia mau mea haumia, ua hoʻoholo mākou i ka hoʻolālā hoʻāʻo penei: ʻO ka mea mua, e hoʻoili i ka ore maka ma o kahi mea hoʻokaʻawale magnetic slurry electromagnetic no ʻelua mau kaʻina hana hoʻokaʻawale magnetic, ka hoʻokaʻawale ʻino a me ke koho maikaʻi, e wehe mua i ka hapa nui o nā mea haumia. A laila, hoʻomaʻemaʻe hou ʻia ka concentrate i loaʻa ma o kahi mea hoʻokaʻawale magnetic superconducting e hōʻemi hou i ka ʻike haumia a hoʻomaikaʻi i ka maikaʻi o Kaolin.

Palapala hoʻokahe hoʻāʻo

Hiki ke ʻike ʻia mai nā hopena hoʻāʻo e hiki ke hoʻokaʻawale ʻia ka ore maka e ka slurry electromagnetic + slurry electromagnetic + ka hoʻokaʻawale magnetic superconducting e loaʻa ai kahi huahana Kaolin concentrate me Fe2O3 0.35% a me ke keʻokeʻo 87.52%.

Kaʻina Hana 2:Hoʻokaʻawale ʻia ka ʻai maka i ka superconducting 5T magnetic. Hōʻike ʻia ke kaʻina hana hoʻāʻo ma ke Kiʻi 2, a hōʻike ʻia nā hopena hoʻāʻo ma ka Papa 2.
