ʻO nā minelala gangue nui i loko o ka lepo ʻoki ʻia, ʻo ia ka feldspar, quartz, calcite, dolomite, amphibole, a pēlā aku. ʻO nā minelala metala nui a me nā haumia, ʻo ia ka silicate hao e like me ka hao mechanical, magnetite, iron oxide, pyrite, a me biotite. I kēia manawa, ʻo ke ʻano hoʻohana piha o ka lepo ʻoki ʻia, ʻo ia ka hana ʻana i nā piliki aerated sima a hana i nā mea maka seramika ma hope o ka wehe ʻana i nā haumia. Loaʻa i ka mea mua kahi mana hana nui a loaʻa i ka mea hope nā pono waiwai kiʻekiʻe.
Noiʻi pōmaikaʻi
Ma kēia ʻatikala, ua hana ʻia ka noiʻi hoʻohana piha a me ka hoʻāʻo hoʻomaikaʻi no ka lepo ʻoki ʻelele ma ka ʻāina ʻo Jining. ʻO nā minelala waiwai i loko o ka lepo ʻoki ʻo ia ka feldspar, ka hao mechanical, ka hao magnetic, a pēlā aku, a ʻo nā mea haumia ʻino he limonite, biotite, muscovite, calcite, dolomite, hornblende, a pēlā aku. ʻAʻole like ka nui o ka mea, ʻo nā ʻāpana coarse mai 1-4mm a me kekahi -0.037mm lepo maikaʻi. I waena o lākou, hiki ke hoʻokaʻawale ʻia ka hao mechanical i hana ʻia i ka wā o ka hana ʻana a me ka hao magnetic i loko o ka ore maka i nā huahana hao concentrate. Ma hope o ka hoʻokaʻawale magnetic ikaika, hiki ke wehe ʻia nā mea haumia hao e like me limonite, biotite, a me amphibole. ʻO nā huahana pōhaku concentrate, hiki ke hoʻohana ʻia kēlā me kēia ʻāpana o nā tailings magnetic e like me nā piliki aerated a i ʻole nā mea sima, i mea e hoʻokō ai i ke kumu o ka hoʻohana piha.
1.Ka hoʻoholo ʻana o ke kahe o ke kaʻina hana
Hoʻohui i nā waiwai o ka hāpana sawdust e hoʻoholo ai i ke kaʻina hana beneficiation: kānana ʻia ka ore maka ma o 30 meshes-+30 mesh coarse-grain grinding a i -30 mesh.
——-30 mesh ka hoʻokaʻawale ʻana i ka hao laʻana i hui ʻia e ka mea hoʻokaʻawale magnetic pahu + papa pālahalaha + apo kū + apo kū ikaika ka wehe ʻana i ka hao magnetic-ua hoʻokaʻawale ʻia ka concentrate i loko o +300 mesh nā huahana concentrate feldspar medium-grain a me -300 mesh mud fine——A laila hoʻohana ʻia ka sludge maikaʻi e wehe i ka hao i ʻelua manawa ma o ka slurry electromagnetic e loaʻa ai kahi huahana concentrate maikaʻi.
2.Hoʻāʻo hoʻokaʻawale magnetic ore maka
Ua kānana ʻia ka ʻaila maka me 30 meshes, a ua hōʻike ʻia nā hopena loiloi ma ka Papa 1.
Papa 1. Hopena o ka Hoʻāʻo Pōmaikaʻi a me ka Nānā ʻana
E wili i ka ʻaihao nui me ka hua o 17.35% a i -30 mesh, e kāwili me ka huahana ma lalo o ke kānana, a e hele ma o ke kaʻina hana hoʻokaʻawale magnetic maʻamau o ka mea hoʻokaʻawale magnetic pahu + papa pālahalaha + apo kū + apo kū. Hōʻike ʻia ke kaʻina hana ma ke Kiʻi 1, a hōʻike ʻia nā hopena hoʻāʻo ma ka Papa 2.
Kiʻi 1. Ke kahe o ke kaʻina hana o ka hoʻāʻo hoʻokaʻawale magnetic maʻamau o ka ore maka.
Papa 2. Nā hopena o ka hoʻāʻo hoʻokaʻawale magnetic maʻamau
Ua kānana ʻia ka ore maka + ka wili ʻana i ka ore + ʻekolu manawa o ka hana hoʻāʻo maʻamau o ka wehe ʻana i ka hao, a hiki ke loaʻa nā huahana concentrate waena a me ka haʻahaʻa me ka hua o 92.57%, kahi ʻike Fe2O3 o 0.525% a me ke keʻokeʻo o 36.15%. Pono e noʻonoʻo ʻia e hoʻomaʻemaʻe i ka oxide hao maikaʻi a me ka silicate hao i loko o ka lepo maikaʻi me kahi mīkini slurry electromagnetic medium maikaʻi, kiʻekiʻe-kahua ma hope o ka hoʻokaʻawale ʻana.
3. Wehe ʻana i ka hao mai ka slurry lepo maikaʻi
Hoʻokuʻu ʻia ka lua o ka hui ʻana o Lihuan mai ka lepo maikaʻi ma lalo o -300 mesh ma o ke kahe ʻana, a hoʻohana ʻia ke kaʻina hana o ka wehe ʻana i ka hao i ʻelua manawa e ka mīkini slurry electromagnetic e loaʻa ai ka huahana hui ʻana o ka pauka maikaʻi. Hōʻike ʻia ke kaʻina hana ma ke Kiʻi 2, a hōʻike ʻia nā hopena hoʻāʻo ma ka Papa 3.
Kiʻi 2. Ke kahe o ke kaʻina hana o ka hoʻāʻo wehe hao slurry lepo maikaʻi
Papa 3. Ka helu wehe hao o ka slurry lepo maikaʻi
Ma hope o ka hoʻokaʻawale ʻana i ka Lihuan concentrate, ua piʻi ka keʻokeʻo o ka +300 mesh medium-grain feldspar concentrate mai 36.15% a i 56.49%, a ua emi ka keʻokeʻo o ka lepo maikaʻi i 23.07%. Hoʻoneʻe ʻia ka -300 mesh fine sludge mai ka hao i ʻelua manawa e ka slurry electromagnetic, a hiki ke loaʻa kahi huahana pauka maikaʻi ceramic me ka hua o 42.31% a me ka keʻokeʻo o 41.80%.
3. Hoʻāʻo kaʻina hana holoʻokoʻa
Nā kūlana hoʻāʻo piha a me nā hōʻailona e hana i ka hoʻāʻo holoʻokoʻa.
Kiʻi 3. Ke kaʻina holoʻokoʻa o ke kaʻina hana hoʻāʻo lepo ʻokiʻoki
Papa 4. Nā hōʻailona hoʻāʻo no ke kaʻina holoʻokoʻa
Hoʻopili: Mahana o nā biscuits 1200℃
Ua kānana ʻia ka ʻai lepo saw + wili ʻia + hoʻokaʻawale magnetic nāwaliwali + papa pālahalaha + apo kū + apo kū + hoʻokaʻawale magnetic slurry electromagnetic e loaʻa ai ka hao hao me ka hua o 0.32% a me ka papa TFe o 62.35%. Me ka hua o 38.56% a me ke keʻokeʻo o 54.69% o nā huahana concentrate feldspar papa keramika waena-palaoa a me ka hua o 42.31% o ke keʻokeʻo o 41.80% o nā huahana concentrate papa keramika pauka maikaʻi; ʻo ka huina o ka hua o nā tailings magnetic he 18.81%, hiki ke hoʻohana ʻia ma ke ʻano he mea maka no nā piliki aerated.
ʻAe kēia kaʻina hana ʻenehana i ka hoʻohana piha ʻana i nā huelo lepo ʻokiʻoki, a hiki ke loaʻa nā pono waiwai kiʻekiʻe a me ke koʻikoʻi o ka palekana kaiāulu.
