Feldspar ndi imodzi mwazomera zomwe zimapezeka kwambiri kumtunda wa kontinenti.Zigawo zake zazikulu zikuphatikizapo SiO2, Al2O3, K2O, Na2O ndi zina zotero.Lili ndi potaziyamu, sodium, calcium ndi barium pang'ono ndi zitsulo zina zamchere kapena zitsulo zamchere zamchere.Monga strategic non-metallic mineral resources, feldspar minerals imagawidwa kwambiri padziko lapansi, ndipo ndi mchere wochuluka kwambiri wa silicate wopangira miyala kupatula quartz.Pafupifupi 60% a iwo amapezeka mu miyala ya magmatic, 30% mu miyala ya metamorphic, ndi 10% mu miyala ya sedimentary, ndi kulemera kwake kwa 50% ya kulemera kwa dziko lapansi. Pali isomorphism yopangidwa bwino mu mchere wa feldspar, ndi mankhwala. kapangidwe kake kamawonetsedwa ndi OrxAbyAnz(x+y+z=100), kumene Or, Ab ndi An amaimira zigawo zitatu za potaziyamu feldspar, albinite ndi calcium feldspar, motsatira.
Malo osungunuka a feldspar nthawi zambiri amakhala pafupifupi 1300 ℃, kachulukidwe kake ndi pafupifupi 2.58g/cm.3, Mos kuuma 6.5, zenizeni yokoka zimasinthasintha pakati pa 2.5-3, Chimaona, psinjika kukana, zabwino grindability ndi ntchito chitukuko, zosavuta crush.Good mankhwala bata, dzimbiri kukana, kupatula mkulu ndende ya asidi sulfuric ndi asidi hydrofluoric; Amathandizira kusungunuka, amagwiritsidwa ntchito ngati flux mu mafakitale a ceramic ndi magalasi;Low index of refraction and birefraction.Ili ndi kuwala kwagalasi, koma nthawi zambiri imakhala ndi mtundu wosiyana chifukwa imakhala ndi zosafunika.Mchere wambiri wa feldspar umagwiritsidwa ntchito ngati zipangizo zamagalasi ndi mafakitale a ceramic, ndi angagwiritsidwenso ntchito mankhwala fetereza, abrasives ndi zida, galasi CHIKWANGWANI ndi mafakitale ena.
02 Zinthu zomwe zimakhudza khalidwe la feldspar
Choyamba ndi chinthu chomwe chili ndi luso lopaka utoto, monga Fe, Ti, V, Cr, Mn, Cu, etc.
Nthawi zonse, Fe ndi Ti ndiye zinthu zazikulu zodaya, zinthu zina ndizochepa kwambiri, digiri yoyera ilibe mphamvu zochepa.
Gulu lachiwiri ndi mchere wakuda, monga biotite, rutile, chlorite ndi zina zotero.Zomwe zili ndi mchere wamdima mu miyala yamchere ndizochepa, koma zimakhudza kwambiri khalidwe la feldspar concentrate.Mtundu wachitatu ndi carbon organic yoyikidwa ndi feldspar, yomwe imapatsa ore mtundu wa imvi-wakuda.Nthawi zambiri, carbon organic imakhala yosavuta kuchotsedwa pa kutentha kwakukulu, ndipo kuyera kumakhala ndi zotsatira zochepa.Zinthu zazikuluzikulu za malonda ndi chitsulo, titaniyamu, ndi chitsulo, ndipo pamwamba pa chinthucho chidzawoneka mawanga akuda, calcium yochuluka kwambiri, pamwamba pa chinthucho ndi yosagwirizana, kotero kuti kupititsa patsogolo ubwino wa mchere wamwala wautali, kugwiritsa ntchito mwala wautali, zomwe zili ndi mchere wakuda ndi mchere. calcium ayenera kuchepetsedwa, makamaka kuchotsa chitsulo okusayidi.
Kukhalapo kwa chitsulo mu feldspar makamaka kumakhala ndi mawonekedwe awa: 1. Ndiwo makamaka monomer kapena aggregate hematite, magnetite ndi limonite ndi kukula kwa tinthu > 0.1mm.Ndiwozungulira, ngati singano, ngati flakelike kapena wosadziwika, womwazika kwambiri mu mchere wa feldspar ndipo ndi wosavuta kuchotsa.Chachiwiri, pamwamba pa feldspar imadetsedwa ndi chitsulo cha oxide mu mawonekedwe a seepage, kapena m'mphepete mwa ming'alu, mchere ndi cleavage joints of feldspar. kugawa malo olowa, okusayidi chitsulo chopangidwa ndi utoto chitsulo kwambiri kumawonjezera vuto la chitsulo kuchotsa.Chachitatu, alipo mu mawonekedwe a chitsulo kubala gangue mchere, monga biotite, limonite, pyrite, ferrotitanium ore, amphibole, epidote ndi zina zotero.
03 Njira zogwiritsira ntchito zopindulitsa za feldspar ore
Pakali pano, ndondomeko yaikulu yotuluka m'nyumba za feldspar ore kuyeretsedwa nthawi zambiri ndi "kuphwanya - kugaya gulu - kupatukana kwa maginito - kuyandama", malinga ndi zosiyana siyana za feldspar mchere wonyansa ndi gangue mineral ophatikizidwa makhalidwe, ndi kulekana ndi manja, deudging, gulu ndi ntchito zina.
(1) kuphwanya ndi kupera
Kuphwanyidwa kwa feldspar kumagawidwa kukhala kuphwanya kwakukulu ndi kuphwanya bwino.Ma ore ambiri amayenera kudutsa njira ziwiri zakuphwanya koopsa komanso kuphwanya kwabwino. Kuphwanya kwakukulu kwa nsagwada, zida zophwanya makamaka zimakhudza mtundu wa crusher, nyundo yamtundu wa nyundo, chopondapo chamtundu, ndi zina zambiri.
Kugaya kwa feldspar kumagawika kwambiri kukhala kugaya kowuma ndi kugaya konyowa.
Kuchita bwino kwa kugaya konyowa ndikwapamwamba kuposa kupukuta kowuma, ndipo chodabwitsa cha "kugwedeza mopitirira muyeso" sichophweka kuwonekera.Zida zogaya zimakhala makamaka mpira, rod mill, tower mill, sanding mill, vibration mill, airflow mill, ndi zina.
(2) Kutsuka ndi desliming
Feldspar ore popanga mapangidwe ochulukirapo kapena ochepa adzakhala ndi slime.Kutsuka makamaka kuchotsa zonyansa monga dongo, matope abwino ndi mica mu feldspar.Kutsuka kungachepetse zomwe zili mu Fe.2O3mu ore, komanso kusintha zomwe zili mu K2O ndi Na2Kutsuka kwa O.Ore ndikolekanitsa ndi mchere wa coarse-grained pansi pa kayendedwe ka madzi pogwiritsa ntchito mawonekedwe a tinthu tating'onoting'ono komanso kuthamanga pang'onopang'ono kwa dongo, matope abwino ndi mica.Zida zomwe zimagwiritsidwa ntchito kwambiri ndi ore ndi makina otsuka, chophimba chogwedeza ndi thanki yochapira miyala.
Cholinga chachikulu cha kuchotsedwa kwa matope ndikuchotsa miyala yamtengo wapatali kuchokera ku miyala yamtengo wapatali ndi yachiwiri ya kalasi yapakatikati ya ndondomeko yowonongeka yosweka, ndikuletsa zotsatira za kusankha kotsatira kwa ufa.Zida zomwe zimagwiritsidwa ntchito nthawi zambiri zimakhala ndi hydraulic cyclone, classifier, centrifuge ndi depuff.
(3) maginito kupatukana
Pogwiritsa ntchito kusiyana kwa maginito pakati pa ores osiyanasiyana, njira yochotsera chitsulo pansi pa mphamvu ya maginito yakunja imatchedwa maginito kupatukana.Feldspar alibe magnetism, koma Fe.2O3ndi mica mu feldspar ndi maginito ofooka, choncho pansi pa chikhalidwe kulimbikitsa kunja maginito, Fe2O3, mica ndi feldspar akhoza kupatukana. olekanitsa maginito, chonyowa maginito mbale maginito olekanitsa, ofukula mphete mkulu gradient maginito olekanitsa, electromagnetic slurry mkulu gradient maginito olekanitsa ndi superconducting mkulu mwamphamvu maginito olekanitsa.
(4) kuyandama
Flotation njira amatanthauza Kuwonjezera wa wothandizila kusintha, wokhometsa thovu wothandizila thovu ndi wothandizila ena mu akupera zopangira zamkati, kuti chitsulo zonyansa Ufumuyo kuwira, kotero kuti ndi zamkati njira, ndiyeno makina scraping, kotero kuti zonyansa zachitsulo ndi zopangira zabwino ufa separation.Flotation ndi njira yothandiza kuchotsa zonyansa za feldspar.Kumbali imodzi, imatha kuchotsa zonyansa monga chitsulo ndi mica, ndipo, kumbali ina, imatha kuwonjezera potaziyamu ndi sodium. akhoza kutengedwa.
