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 mea 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 i nā minerala hana pōhaku silicate koe wale 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 ka nui o ke kaumaha o 50% o ka honua holoʻokoʻa. 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 nui ma kahi o 2.58g / cm3, Mos paakiki 6.5, ka umekaumaha kiko'ī fluctuates ma waena o 2.5-3, brittle, compression kū'ē, grindability maikaʻi 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 waika; hoʻohana maʻamau e like me ka flux i loko o ka ceramic a me ke aniani ʻoihana; Low index of refraction and birefraction. It has a glassy luster, but often has a different color because it have impurities. Most of feldspar minerals are used as raw materials for glass and ceramic industry, and 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 hoʻoluu nui, liʻiliʻi liʻiliʻi nā mea ʻē aʻe, liʻiliʻi ka mana keʻokeʻo.
ʻO ka lua o ka ʻāpana he mau minela ʻeleʻele, e like me biotite, rutile, chlorite a pēlā aku. 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 ke kiʻekiʻe 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 ʻike ʻia ka ʻili o ka huahana i nā kikoʻeleʻele, ʻoi aku ka kiʻekiʻe o ka calcium, ʻaʻole kūlike ka ʻili o ka huahana, no laila e hoʻomaikaʻi i ka maikaʻi o nā minerala pōhaku lōʻihi, ka hoʻohana ʻana i ka pōhaku lōʻihi, ka ʻike o nā mineral ʻeleʻele a pono e hoemiia ka calcium, o ka wehe ana 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 nā mineral feldspar a maʻalahi e 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 hoʻokaʻawale ʻana - ka hoʻokaʻawale ʻana i ka magnetic - flotation", e like me ka ʻokoʻa feldspar mineral haumia maʻiʻo a me ka gangue mineral i hoʻokomo ʻia i nā ʻano, 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 i ka 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 ʻoki 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 haumia e like me ka pālolo, ka lepo maikaʻi a me ka mika i loko o ka feldspar. Hiki i ka holoi ʻana ke hōʻemi 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, ʻo ke kaʻina hana o ka wehe ʻana i ka hao ma lalo o ka hana o ka pā magnetic waho i kapa ʻia ʻo ka hoʻokaʻawale magnetic. ʻAʻohe magnetism ʻo Feldspar, akā ʻo Fe2O3a me ka mica i loko o ka feldspar he mea nawaliwali ka magnetism, no laila ma lalo o ke ʻano o ka hoʻoikaika ʻana i ke kahua mākēneki waho, hiki ke hoʻokaʻawale ʻia ʻo Fe2O3, mica a me feldspar. I kēia manawa, ʻo ka mea maʻamau i hoʻohana ʻia i nā mea hoʻokaʻawale magnetic ma Kina ka mea nui loa e pili ana i ka mea hoʻokaʻawale honua ʻole, ka pahu hoʻokalakupua mau. 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. ka hao haumia a me ka maka mea fine pauda separation.Flotation mea he ala maikai e wehe i 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.
