01 hōʻuluʻulu manaʻo
ʻO Feldspar kekahi o nā minerale maʻamau i loko o ka ʻōpala ʻāina. ʻO kona mau mea nui he SiO2, Al2O3, K2O, Na2ʻO a pēlā aku. Loaʻa iā ia ka potassium, sodium, calcium a me kahi liʻiliʻi o ka barium a me nā metala alkali a i ʻole nā metala honua alkaline. Ma ke ʻano he kumu waiwai mineral non-metallic, ua laha nui ʻia nā mineral feldspar i loko o ka ʻōpala o ka honua, a ʻo ia ka mea i hoʻolaha nui ʻia nā minerala hana pōhaku silicate koe wale nō ka quartz. Ma kahi o 60% o ia mau mea i loaʻa i loko o nā pōhaku magmatic, 30% i nā pōhaku metamorphic, a me 10% i nā pōhaku sedimentary, me ke kaumaha o 50% o ka nui o ka honua. hōʻike pinepine ʻia ka haku mele e OrxAbyAnz(x+y+z=100), kahi ʻo Or, Ab a me An e hōʻike ana i ʻekolu ʻāpana o ka pāpaʻa feldspar, albinite a me ka calcium feldspar.
ʻO ka helu hoʻoheheʻe o feldspar ma kahi o 1300 ℃, ʻo ka mānoanoa ma kahi o 2.58g / cm3, Mos paakiki 6.5, ka umekaumaha kiko'ī fluctuates ma waena o 2.5-3, brittle, hoʻopiʻi kū'ē, maikaʻi grindability a me ka hoʻomohala hana, oluolu e crush.Good kemika paʻa, corrosion kū'ē, koe ka kiʻekiʻe o ka sulfuric acid a me ka hydrofluoric acid; Kōkua heheʻe hana, hoʻohana maʻamau e like me ka flux i loko o ka ceramic a me ke aniani ʻoihana; Low index of refraction and birefraction.It he aniani luster, akā pinepine ka waihoʻoluʻu ʻokoʻa no ka mea i loko o nā haumia. hiki ke hoʻohana ʻia no ka hoʻomaʻamaʻa fertilizer, abrasives a me nā mea hana, aniani fiber a me nā ʻoihana ʻē aʻe.
02 Nā mea e pili ana i ka maikaʻi o feldspar
ʻO ka mea mua ka mea me ka hiki ke kala, e like me Fe, Ti, V, Cr, Mn, Cu, etc.
Ma lalo o nā kūlana maʻamau, ʻo Fe a me Ti nā mea hoʻoluʻu nui, liʻiliʻi liʻiliʻi nā mea ʻē aʻe, liʻiliʻi ka mana keʻokeʻo.
ʻO ka lua o ka ʻāpana he mau mineral ʻeleʻele, e like me biotite, rutile, chlorite a me nā mea ʻē aʻe. feldspar, ka mea e hāʻawi ai i ka ʻeleʻele hina-ʻeleʻele. I ka hapanui o nā hihia, ua maʻalahi ka wehe ʻana o ke kalapona organik i ka wela 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 ʻo ka ʻili o ka huahana e ʻike ʻia nā kikoʻeleʻele, kiʻekiʻe ka nui o ka calcium, ʻaʻole kūlike ka ʻili o ka huahana, no laila e hoʻomaikaʻi i ka maikaʻi o nā minerala pōhaku lōʻihi, ka noi ʻana o ka pōhaku lōʻihi, ka ʻike o nā minela ʻeleʻele a pono e hoemi ia ka calcium, o ka hoopau loa i ka hao oxide.
ʻO ka noho ʻana o ka hao i loko o ka feldspar ka nui o nā ʻano penei: 1. ʻO ka monomer a i ʻole aggregate o ka hematite, magnetite a me limonite me ka nui o ka nui o >0.1mm. He spherical, nila-like, flakelike a iʻole likeʻole, hoʻopuehu nuiʻia i loko o nā minela feldspar a maʻalahi ke wehe. ʻO ka hāʻawiʻana i ke komoʻana,ʻo ka hao hao i hanaʻia e ka hao hao e hoʻonui nui i ka paʻakikī o ka hao.
03 Hoʻohana maʻamau i nā ʻano hoʻomaikaʻi ʻana o ka feldspar ore
I kēia manawa, ʻo ke kaʻina hana nui o ka hoʻomaʻemaʻe ʻana i ka ʻāina feldspar ʻo ka maʻamau "ka ʻohi ʻana - ka ʻili ʻana i ka hoʻokaʻawale ʻana - ka hoʻokaʻawale ʻana i ka magnetic - flotation", e like me nā ʻano feldspar mineral haumia ʻokoʻa a me nā hiʻohiʻona i hoʻokomo ʻia i ka mineral gangue, a me ka hoʻokaʻawale lima, desudging, classification a me nā hana ʻē aʻe.
（1） ka wili a me ka wili
Hoʻokaʻawale ʻia ka ʻoki ʻana o feldspar i ka ʻohi ʻana a me ka ʻili maikaʻi. ʻO ka hapa nui o nā ores e hele i nā kaʻina hana ʻelua o ka ʻohi ʻana a me ka ʻohi maikaʻi.
Hoʻokaʻawale ʻia ka wili ʻana o feldspar 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 ka ʻike ʻana i ke ʻano o ka "over-grinding". etc.
（2）Ka holoi ʻana a me ka holoi ʻana
ʻO ka Feldspar ore i ke kaʻina hana o ka hoʻokumu ʻana a i ʻole ka liʻiliʻi e loaʻa i kahi nui o ka slime. ʻO ka holoi ʻana ka mea nui e wehe i nā mea haumia e like me ka pālolo, ka lepo maikaʻi a me ka mika i loko o ka feldspar. Hiki i ka holoi ʻana ke hoʻemi i ka ʻike o Feldspar.2O3i loko o ka oka, a hoʻomaikaʻi hoʻi i ka ʻike o K2O a me Na2ʻO ka holoi ʻana o O.Ore ka mea e hoʻokaʻawale ai i nā minerala koʻikoʻi ma lalo o ke kahe o ka wai ma o ka hoʻohana ʻana i nā hiʻohiʻona o ka liʻiliʻi liʻiliʻi a me ka wikiwiki o ka hoʻonohonoho ʻana o ka pālolo, lepo maikaʻi a me ka mika. pale kuʻi a me ka pahu holoi wai.
ʻO ke kumu nui o ka weheʻana i ka lepo,ʻo ia ka weheʻana i ka'ōmole'ōiwi mai ka'ōpala a me ka lua o ka'enela o ka papa waena o ke kaʻina hana wili, a pale i ka hopena o ke kohoʻana o ka pauda. ʻO ka mea hoʻohana maʻamau deputer he hydraulic cyclone, classifier, centrifuge a me depuff.
（3）ka hoʻokaʻawale mākēneki
Ke hoʻohana nei 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 o waho.2O3a me ka mica i loko o ka feldspar he nāwaliwali ka magnetism, no laila ma lalo o ke ʻano o ka hoʻoikaika ʻana i ke kahua magnetic waho, hiki ke hoʻokaʻawale ʻia ʻo Fe2O3, mika a me feldspar. mea hoʻokaʻawale mākēneki, ka mea hoʻokaʻawale mākēneki pulu, ke apo kū pololei, ka mea hoʻokaʻawale magnetic gradient kiʻekiʻe.
（4）holo
ʻO ke ʻano o ka Flotation e pili ana i ka hoʻohui ʻana o ka mea hoʻoponopono, ʻohi ʻohi, ʻona a me nā mea ʻē aʻe i ka wili ʻana i ka pulp maka, i hoʻopili ʻia nā haumia hao i ka ʻōhū, a me ka hopena pulp, a laila ʻokiʻoki i waho, no laila. ʻO nā mea hao a me nā mea maka ka pauka maikaʻi separation.Flotation kahi ala kūpono e wehe ai i ka haumia o feldspar. Ma kekahiʻaoʻao, hiki iā ia ke wehe i nā mea haumia e like me ka hao a me ka mica, a ma kekahiʻaoʻao, hiki ke hoʻonui i ka nui o ka potassium a me ka sodium. Keʻano likeʻole ka mineral, heʻokoʻa ke koho o ka mea hopu, akāʻo ke kaʻina hana hoʻohuli. hiki ke aponoia.
