ʻO ka ʻōpala ʻili kahi hui ʻana o ka pauka pōhaku a me ka wai i hana ʻia i ka wā o ka ʻoki ʻana a me ka hoʻoliʻiliʻi ʻana i ke kinikini a me ka granite. ʻO nā wahi he nui ma ka ʻākau o ko mākou ʻāina he mau kumu hoʻoheheʻe pōhaku koʻikoʻi, a ua hana ʻia ka nui o ka ʻili lepo i kēlā me kēia makahiki, a lawe ʻia kona hoʻopaʻa ʻana. piʻi i kahi nui o nā kumuwaiwai ʻāina. He ʻano maikaʻi ko ka pauda pōhaku a paʻakikī ke hoʻolei. He mea maʻalahi ke lele i ka lewa i ka makani ikaika, a kahe i loko o ka muliwai me ka wai ua i nā lā ua, e hoʻohaumia ana i ke kaiapuni.
ʻO nā mineral gangue nui i loko o ka lepo iʻikeʻia he feldspar, quartz, calcite, dolomite, amphibole, a me nā mea'ē aʻe. ʻO ke ʻano o ka ʻike ʻana i ka lepo ka mea nui e hana i nā pōhaku lepo aerated a hana i nā mea waiwai ceramic ma hope o ka wehe ʻana i nā haumia. Loaʻa i ka mua ka mana hana nui a ʻo ka hope he mau pono waiwai kiʻekiʻe.
Ka noiʻi pōmaikaʻi
Ma kēia 'atikala, ua lawe 'ia ka ho'ohana 'ana a me ka pōmaika'i noi'i ho'ā'o no ka 'ike 'ana i ka lepo i loko o Jining wahi. 'O nā minela waiwai i loko o ka saw mud he feldspar, mechanical iron, magnetic iron, etc., a me na haumia ino he limonite, biotite, muscovite, calcite, dolomite, hornblende, a me nā mea ʻē aʻe. ʻAʻole kūlike ka nui o nā mea, ʻo nā ʻāpana koʻikoʻi mai ka 1-4mm a me kekahi -0.037mm lepo maikaʻi. Ma waena o lākou, ka hao mechanical i hana ʻia i ka wā o ka hana ʻana a me ka hao magnetic i ka maka. hiki ke hoʻokaʻawale ʻia ka ʻeleʻele i loko o nā huahana concentrate hao. Ma hope o ka hoʻokaʻawale ikaika ʻana, hiki ke wehe ʻia nā mea haumia hao e like me ka limonite, biotite, a me amphibole. ʻO nā huahana concentrate pōhaku, hiki ke hoʻohana ʻia kēlā me kēia ʻāpana o nā tailing magnetic e like me nā pōhaku aerated a i ʻole nā mea sima, i mea e hoʻokō ai i ke kumu o ka hoʻohana piha ʻana.
1.Hoʻoholo kaʻina hana
ʻO ka hui pū ʻana i nā waiwai o ka sawdust sample e hoʻoholo ai i ke kaʻina hana pono: ua kānana ʻia ka ʻaila maka ma o 30 meshes-+30 mesh coarse-grain grinding i -30 mesh.
——-30 mesh i hui ʻia i ka hao hoʻokaʻawale ʻia e ka pahu hoʻokaʻawale hoʻokaʻawale + pā pālahalaha + apo kū pololei + apo kūpaʻa ikaika hoʻoneʻe hao magnetic-ua hoʻokaʻawale ʻia ka concentrate i loko o +300 mesh medium-grain feldspar concentrate huahana a -300 mesh mud fine.——Hoʻohana ʻia ka ʻōpala maikaʻi e wehe i ka hao ʻelua ma o ka slurry electromagnetic no ka loaʻa ʻana o kahi huahana concentrate pauda maikaʻi.
2.ʻO ka hoʻāʻo hoʻokaʻawale ʻana i ka ʻeleʻele maka
Ua kānana ʻia ka ʻai maka me 30 meshes, a ua hōʻike ʻia nā hopena hōʻike ma ka Papa 1.
Papa 1. Ka hopena o ka pono a me ka hoao ana
E wili i ka oka coarse-grained me ka hua o 17.35% a -30 mesh, hui me ka huahana ma lalo o ke kānana, a hele i loko o ke kaʻina hana hoʻokaʻawale maʻamau o ka pahu hoʻokaʻawale hoʻokaʻawale + papa pālahalaha + apo kū pololei + apo kū pololei. Hōʻike ʻia ke kahe kaʻina hana ma ke Kiʻi 1, a hōʻike ʻia nā hopena hōʻike ma ka Papa 2.
Kiʻi 1. Ke kahe kaʻina o ka ho'āʻo hoʻokaʻawale magnetic maʻamau o ka oka maka.
Papa 2. Nā hopena o ka ho'āʻo hoʻokaʻawale magnetic maʻamau
Hoʻopaʻa ʻia ka ʻeleʻele maka + wili ʻai + ʻekolu mau manawa hao e wehe i ke kaʻina hoʻāʻo maʻamau, a hiki ke loaʻa ka waena a me nā huahana concentrate haʻahaʻa me kahi hua o 92.57%, kahi Fe2O3 maʻiʻo o 0.525% a me kahi keʻokeʻo o 36.15%. Pono e noʻonoʻo ʻia e hoʻomaʻemaʻe i ka hao oxide a me ka hao silicate i loko o ka lepo maikaʻi me ka mīkini slurry electromagnetic kiʻekiʻe ma hope o ka helu ʻana.
3. ʻO ka hao ʻana mai ka lepo lepo maikaʻi
Hoʻokuʻu ʻia ka lua o Lihuan mai ka lepo maikaʻi ma lalo o -300 mesh ma o ka overflow, a ʻo ke kaʻina hana o ka wehe ʻana i ka hao ʻelua e ka mīkini slurry electromagnetic e hoʻohana ʻia no ka loaʻa ʻana o ka huahana concentrate pauda. Hōʻike ʻia ke kahe kaʻina hana ma ke Kiʻi 2, a hōʻike ʻia nā hopena hōʻike ma ka Papa 3.
Kiʻi 2. ʻO ke kaʻina hana o ka ho'āʻo hoʻohemo ʻana i ka hao lepo lepo maikaʻi
Papa 3. Helu hoopau hao o ka lepo lepo maikai
Ma hope o ka helu ʻana i ka concentrate Lihuan, ua hoʻonui ke keʻokeʻo o ka +300 mesh medium-grain feldspar concentrate mai 36.15% a i 56.49%, a ua emi ke keʻokeʻo o ka lepo maikaʻi i 23.07%. -300 mesh fine sludge ua wehe ʻia mai ka hao ʻelua e ka electromagnetic slurry, a hiki ke loaʻa i kahi huahana pauka ceramic-grade me kahi hua o 42.31% a me kahi keʻokeʻo o 41.80%.
3.Whole kaʻina ho'āʻo
Nā kūlana ho'āʻo piha a me nā hōʻailona e hana i ke kaʻina hana holoʻokoʻa.
Kiʻi 3. ʻO ke kaʻina hana holoʻokoʻa o ka ʻeli ʻana i ka lepo
Papa 4. Nā hōʻailona hōʻike no ka hana holoʻokoʻa
Pākuʻi: Pīkī wela 1200 ℃
Ua kānana ʻia ka ʻōpala lepo + lepo + hoʻokaʻawale mākaʻikaʻi nāwaliwali + pā pālahalaha + apo kū pololei + apo kū pololei + grading electromagnetic slurry magnetic separation kaʻina no ka loaʻa ʻana o ka hao hao me kahi hua o 0.32% a me kahi papa TFe o 62.35%. Me ka hua o 38.56% a me ke keʻokeʻo o 54.69% o ka medium-grain ceramic grade feldspar concentrate huahana a me ka hua o 42.31% o keokeo o 41.80% fine powder ceramic grade concentrate huahana; ʻO ka nui o ka hua o nā tailing magnetic he 18.81%, hiki ke hoʻohana ʻia e like me nā mea maka no nā pōhaku lepo.
Hiki i kēia kaʻina hana ʻenehana ke hoʻohana piha i nā huelo ʻōpala, a hiki ke loaʻa nā pōmaikaʻi waiwai kiʻekiʻe a me ke koʻikoʻi o ka mālama kaiapuni.
