ʻO Feldspar kekahi o nā minelala maʻamau i ka ʻili honua. ʻO kāna mau ʻāpana nui e komo pū me SiO2, ʻAl2O3, K2ʻO, Na2ʻO a pēlā aku. Loaʻa iā ia ka potassium, sodium, calcium a me kahi liʻiliʻi o ka barium a me nā metala alkali ʻē aʻe a i ʻole nā metala alkaline honua. Ma ke ʻano he mau kumuwaiwai mineral non-metallic koʻikoʻi, ua hoʻolaha nui ʻia nā mineral feldspar i loko o ka ʻili o ka honua, a ʻo ia nā mineral silicate rock-forming i hoʻolaha nui ʻia koe wale nō ka quartz. Ma kahi o 60% o lākou e kū mai ana i nā pōhaku magmatic, 30% i nā pōhaku metamorphic, a me 10% i nā pōhaku sedimentary, me ke kaumaha holoʻokoʻa o 50% o ke kaumaha holoʻokoʻa o ka honua. Aia kahi isomorphism i hoʻomohala maikaʻi ʻia i nā mineral feldspar, a ua hōʻike pinepine ʻia ke ʻano kemika e OrxAbyAnz(x+y+z=100), kahi e hōʻike ai ʻo Or, Ab a me An i ʻekolu mau ʻāpana o ka potassium feldspar, albinite a me ka calcium feldspar.
ʻO ka pae hoʻoheheʻe o ka feldspar ma kahi o 1300 ℃, ʻo ka nui o ka nui ma kahi o 2.58g / cm3, ʻO ka paʻakikī Mos 6.5, ʻo ke kaumaha kikoʻī e loli ma waena o 2.5-3, palupalu, kū'ē i ka compression, wili maikaʻi a me ka hana hoʻomohala, maʻalahi ke kuʻi. Paʻa kemika maikaʻi, kū'ē i ka corrosion, koe wale nō ka nui o ka sulfuric acid a me ka hydrofluoric acid; Kōkua i ka hana hoʻoheheʻe, hoʻohana pinepine ʻia e like me ka flux i ka ʻoihana keramika a me ke aniani; Kuhi haʻahaʻa o ka refraction a me ka birefraction. He luster aniani kona, akā pinepine he kala ʻokoʻa no ka mea he mau haumia. Hoʻohana ʻia ka hapa nui o nā minela feldspar ma ke ʻano he mea maka no ka ʻoihana aniani a me ka keramika, a hiki ke hoʻohana ʻia no ka mālama ʻana i nā mea hoʻouluulu, nā abrasives a me nā mea hana, nā fiber aniani a me nā ʻoihana ʻē aʻe.
02 Nā mea e pili ana i ka maikaʻi o ka feldspar
ʻO ka mea mua ka element me ka hiki ke hoʻoluʻu, e like me Fe, Ti, V, Cr, Mn, Cu, a pēlā aku.
Ma lalo o nā kūlana maʻamau, ʻo Fe a me Ti nā mea hoʻoluʻu nui, he liʻiliʻi loa ka nui o nā mea ʻē aʻe, a he liʻiliʻi ka mana o ke kekelē keʻokeʻo.
ʻO ka lua o ka māhele he mau minelala ʻeleʻele, e like me ka biotite, rutile, chlorite a pēlā aku. He haʻahaʻa ka nui o nā minelala ʻeleʻele i loko o nā pōhaku minelala, akā he mana nui kona i ka maikaʻi o ka feldspar concentrate. ʻO ke kolu o ke ʻano, ʻo ia ke kalapona organik i waiho ʻia me ka feldspar, ka mea e hāʻawi ai i ka ore i kahi kala hina-ʻeleʻele. I ka hapanui o nā hihia, maʻalahi ke wehe ʻia ke kalapona organik i ka mahana kiʻekiʻe, a he liʻiliʻi ka hopena o ke keʻokeʻo. ʻO nā mea nui o nā huahana ʻoihana he hao, titanium, a me ka hao, a e ʻike ʻia nā kiko ʻeleʻele ma luna o ka huahana, kiʻekiʻe loa ka nui o ka calcium, ʻaʻole like ka ʻili o ka huahana, no laila e hoʻomaikaʻi i ka maikaʻi o nā minelala pōhaku lōʻihi, pono e hoʻemi ʻia ka nui o nā minelala ʻeleʻele a me ka calcium, ʻoiai ka wehe ʻana o ka oxide hao.
ʻO ke ʻano o ka hao ma ka feldspar penei: 1. ʻO ia ka monomer a i ʻole ka hui ʻana o ka hematite, magnetite a me ka limonite me ka nui o ka ʻāpana o >0.1mm. He poepoe, like me ke kui, flakelike a i ʻole irregular, hoʻopuehu nui ʻia i loko o nā minelala feldspar a maʻalahi hoʻi e wehe. ʻO ka lua, ua haumia ka ʻili o ka feldspar e ka hao oxide ma ke ʻano o ka seepage, a i ʻole ma nā māwae, nā minelala a me nā hui cleavage o ka hoʻolaha komo ʻana o ka feldspar, ʻo ka hao oxide i hana ʻia e ka dye hao e hoʻonui nui i ka paʻakikī o ka wehe ʻana i ka hao. ʻO ke kolu, aia ia ma ke ʻano o nā minelala gangue hao, e like me biotite, limonite, pyrite, ferrotitanium ore, amphibole, epidote a pēlā aku.
03 Nā ʻano hana hoʻomaikaʻi i hoʻohana pinepine ʻia o ka feldspar ore
I kēia manawa, ʻo ke kaʻina hana nui o ka hoʻomaʻemaʻe ʻana o ka feldspar ore kūloko, ʻo ia ka "crushing - grinding classification - magnetic separation - flotation", e like me nā ʻano haumia mineral feldspar like ʻole a me nā ʻano i hoʻokomo ʻia o ka mineral gangue, a me ka hoʻokaʻawale lima, desudging, classification a me nā hana ʻē aʻe.
（1） ke kuʻi ʻana a me ka wili ʻana
Ua māhele ʻia ka wāwahi ʻana o ka feldspar i ka wāwahi ʻana i ka coarse a me ka wāwahi maikaʻi. Pono ka hapa nui o nā ores e hele ma o nā kaʻina hana ʻelua o ka wāwahi ʻana i ka coarse a me ka wāwahi maikaʻi. ʻO ka wāwahi ʻana i ka hapa nui o ka mīkini wili ʻāwae, nā lako hana wili ʻoi aku ka hopena o ka hopena, ka mīkini wili hāmare, ka mīkini wili ʻano hopena, a pēlā aku.
ʻO ka wili ʻana o ka feldspar ua māhele nui ʻia i ka wili maloʻo a me ka wili pulu.
ʻOi aku ka maikaʻi o ka wili pulu ma mua o ka wili maloʻo, a ʻaʻole maʻalahi ke ʻike ʻia ke ʻano o ka "wili nui". ʻO nā lako wili ka wili pōpō, ka wili koʻokoʻo, ka wili hale kiaʻi, ka wili sanding, ka wili haʻalulu, ka wili airflow, a pēlā aku.
（2）Ka holoi ʻana a me ka wehe ʻana i ka lepo
ʻO ka ʻaile Feldspar i ke kaʻina hana o ka hoʻokumu ʻana he nui a emi mai paha e loaʻa kahi nui o ka slime. ʻO ka holoi ʻana ke kumu nui o ka wehe ʻana i nā mea haumia e like me ka lepo, ka lepo maikaʻi a me ka mica i loko o ka feldspar. Hiki i ka holoi ʻana ke hōʻemi i ka ʻike o Fe2O3i loko o ka ore, a hoʻomaikaʻi pū i ka ʻike o K2ʻO a me Na2ʻO ka holoi ʻana i ka ʻoaka, ʻo ia ke hoʻokaʻawale ʻana mai nā minelala ʻili lahilahi ma lalo o ka hana o ke kahe ʻana o ka wai ma o ka hoʻohana ʻana i nā ʻano o ka nui o nā ʻāpana liʻiliʻi a me ka wikiwiki o ka noho ʻana o ka lepo, ka lepo maikaʻi a me ka mika. ʻO nā mea holoi ʻoaka i hoʻohana pinepine ʻia, ʻo ia ka mīkini holoi, ka pale haʻalulu a me ka pahu holoi ʻoaka.
ʻO ke kumu nui o ka wehe ʻana i ka lepo, ʻo ia ka wehe ʻana i ka ʻai maoli mai ka ʻai a me ka ʻai lua o ka papa waena o ke kaʻina hana wili haʻihaʻi, a pale i ka hopena o ke koho ʻana o ka pauka ma hope. ʻO ka lako deputer maʻamau he cyclone hydraulic, classifier, centrifuge a me depuff.
（3）ka hoʻokaʻawale magnetic
Ma ka hoʻohana ʻana i ka ʻokoʻa magnetic ma waena o nā ores like ʻole, ua kapa ʻia ke kaʻina hana o ka wehe ʻana i ka hao ma lalo o ka hana o ke kahua magnetic waho i ka hoʻokaʻawale magnetic. ʻAʻohe magnetism o Feldspar, akā ʻo Fe2O3a he nāwaliwali ka magnetism o ka mica ma feldspar, no laila ma lalo o ke kūlana o ka hoʻoikaika ʻana i ke kahua magnetic waho, hiki ke hoʻokaʻawale ʻia ʻo Fe2O3, mica a me feldspar. I kēia manawa, ʻo nā lako hoʻokaʻawale magnetic i hoʻohana nui ʻia ma Kina e komo pū ana me ka mea hoʻokaʻawale magnetic roller honua laha ʻole, ka mea hoʻokaʻawale magnetic drum magnet mau loa, ka mea hoʻokaʻawale magnetic plate magnetic pulu, ka mea hoʻokaʻawale magnetic gradient kiʻekiʻe o ke apo kū pololei, ka mea hoʻokaʻawale magnetic gradient kiʻekiʻe o ka slurry electromagnetic a me ka mea hoʻokaʻawale magnetic superconducting kiʻekiʻe.
（4）lana
ʻO ke ʻano flotation e pili ana i ka hoʻohui ʻana o ka mea hoʻoponopono, ka mea hōʻiliʻili, ka mea hoʻopū a me nā mea ʻē aʻe i loko o ka pulp mea maka wili, i hoʻopili ʻia nā haumia hao i ka pehu, i hiki ai iā ia a me ka hopena pulp, a laila ke kahakaha ʻana i waho, i hoʻokaʻawale ʻia nā haumia hao a me ka pauka maikaʻi o nā mea maka. ʻO ka flotation kahi ala kūpono e wehe ai i ka haumia o ka feldspar. Ma kekahi ʻaoʻao, hiki iā ia ke wehe i nā haumia e like me ka hao a me ka mica, a ma kekahi ʻaoʻao, hiki iā ia ke hoʻonui i ka nui o ka potassium a me ka sodium. Ke ʻokoʻa ka mineral, ʻokoʻa ke koho ʻana o ka mea hopu, akā hiki ke hoʻohana ʻia ke kaʻina hana flotation hope.
