I-Feldspar iyiminerali ye-aluminosilicate yezinsimbi ze-alkali kanye nezinsimbi zomhlaba ze-alkaline njenge-potassium, i-sodium kanye ne-calcium. Inomndeni omkhulu futhi iyiminerali evame kakhulu yokwakha amatshe. Itholakala kabanzi emadwaleni ahlukahlukene e-magmatic nasemadwaleni e-metamorphic, ebalelwa cishe ku-50% woqweqwe oluphelele, lapho cishe u-60% we-feldspar ore etholakala emadwaleni e-magmatic. Imayini ye-feldspar yakhiwe kakhulu yi-potassium ne-albite ecebile nge-potassium noma i-sodium, futhi intuthuko yayo ezintweni zobumba, embonini yezempi, embonini yamakhemikhali, kwezokwakha nakwezinye izimboni "ingamandla amakhulu". Isetshenziswa kakhulu njengezinto zobumba embonini yengilazi ukukhiqiza imikhiqizo yengilazi efana nengilazi eyisicaba, izinto zengilazi kanye ne-fiber yengilazi; okwesibili, isetshenziswa njengezinto zobumba kanye ne-glaze ukukhiqiza amathayili odonga, izinto zobumba zamakhemikhali, izinto zobumba zikagesi kanye ne-mill linings; isetshenziswa kakhulu njengezinto zobumba zamakhemikhali zokukhiqiza izitsha zerabha nepulasitiki kanye nokukhiqizwa komanyolo wamakhemikhali, njll.; uma isetshenziswa njengezinto zokwakha, ikhiqiza kakhulu usimende okhethekile kanye ne-fiber yengilazi.
Ngemva kokukhishwa kwe-“Uhlelo Lweminyaka Emihlanu Lwezimayini Ezingezona Insimbi kanye Nombono Ka-2035″, “Uhlelo” lufingqa impumelelo enhle nezinkinga zentuthuko ye-“Uhlelo Lweminyaka Emihlanu Lwe-13”; luhlaziya indawo yentuthuko kanye nesidingo semakethe, futhi luphakamisa ukuthi kuklanywe imibono emisha eqondisayo, izimiso zentuthuko eziyisisekelo, kanye nemigomo eyinhloko, futhi imisebenzi ebalulekile, amaphrojekthi abalulekile kanye nezinyathelo zokuphepha kucacisiwe.
Imboni yezimayini ezingezona ezensimbi ilwela ukusebenzisa umqondo omusha wentuthuko, ibamba ngokuqinile ithuba elibalulekile lokuthi intuthuko yezomnotho yezwe lami ingena ekuthuthukisweni kwekhwalithi ephezulu, icwaninga futhi idwebe "Imibono Eqondisayo Ekukhuthazeni Intuthuko Esezingeni Eliphezulu Yemboni Yezimayini Ezingezona ezensimbi", futhi iphakamisa intuthuko esezingeni eliphezulu yezimpawu zemboni, izinhloso zomsebenzi, izimiso eziyisisekelo kanye nezivikelo; Hlela ukuhlanganiswa kwe-"2021-2035 Non-metallic Mining Industry Technology Development Roadmap", ihlele futhi icacise izidingo zentuthuko, izinto eziza kuqala ekuthuthukisweni, amaphrojekthi amakhulu kanye namaphrojekthi okubonisa ubuchwepheshe bezimayini ezingezona ezensimbi ngezigaba, futhi ithuthukise isiqondiso nenhloso yokusungula izinto ezintsha kwesayensi nobuchwepheshe embonini; Hlela ukwakheka "koHlelo Lokusebenza Locwaningo Olusha kanye Nokuthuthukiswa Kobuchwepheshe Nemishini Yesizukulwane Esisha Embonini Yezimayini Ezingezona ezensimbi", futhi ibeke phambili imigomo nemisebenzi yocwaningo olusha kanye nokuthuthukiswa kwesizukulwane esisha sobuchwepheshe bezimayini ezingezona ezensimbi kanye nemishini.
Indandatho eqondile epholisa amanzi ahlanganisiwe e-oyili-indandatho ehlukanisiwe enamandla amakhulu kagesi
Yabhalwa yi-China Non-metallic Mining Industry Association, kanti uMnyango Wezinsiza Zemvelo wakhipha futhi wasebenzisa indinganiso ethi “Imininingwane Yokwakhiwa Kwezimayini Eziluhlaza Embonini Yezimayini Ezingezona Zensimbi”. Umsebenzi wokubonisa wokuhlola wokukhiqiza okuhlakaniphile ezicini ezimbili ezibalulekile “zokukhiqiza imishini” kanye “nokukhiqizwa komkhiqizo” wenziwe, okukhuthaze ukuthuthukiswa okujulile kokukhiqiza okuhlakaniphile embonini yezimayini ezingezona ezensimbi. Kuhlelwe futhi kwenziwa ucwaningo ngobuchwepheshe obusha kanye nezinqubo ezintsha ezifana nobuchwepheshe bokucubungula okujulile obungenawo umsila, ubuchwepheshe bokuchoboza nokuhlanza okomile, kanye nokulungiswa kwezinto ezinezimbobo ezivela kumaminerali e-silicate; kuthuthukiswe ngempumelelo abahlukanisi bamagnetic abanamandla amakhulu, abahlukanisi bamagnetic abaqhuba i-superconducting, amasethi amakhulu aphelele emigqa yokukhiqiza yokuchoboza, ukukala kahle nokuguqulwa, abahlaziyi besistimu yokuma kwezinhlayiya ezinembayo ephezulu kanye nezinye izinsimbi ezintsha kanye nemishini emisha.
IShayina iyizwe elinemithombo emikhulu ye-feldspar ore. Izindawo ezigciniwe ze-feldspar ore zamabanga ahlukahlukene zingamathani ayizigidi ezingama-40.83. Iningi lalawa ma-deposit yi-pegmatite deposits, okuyizinhlobo eziyinhloko zama-deposits athuthukiswe futhi asetshenziswa njengamanje. Ngokusho kwe-China Building Materials Industry Standard (JC/T-859-2000), i-feldspar ore ihlukaniswe ngezigaba ezimbili (i-potassium feldspar, i-albite) kanye namazinga amathathu (umkhiqizo ophakeme, umkhiqizo wekilasi lokuqala, umkhiqizo ofanelekayo). E-Anhui, eShanxi, eShandong, eHunan, eGansu, eLiaoning, eShaanxi nakwezinye izindawo.
Ngokusho kokuqukethwe kwe-potassium, i-sodium, i-silicon nezinye izakhi, ukusetshenziswa okuyinhloko kwamaminerali e-feldspar nakho kuhlukile. Izindlela zokuzuza i-Feldspar ngokuyinhloko ziwukuhlukaniswa kwamagnetic kanye nokuntanta. Ukuhlukaniswa kwamagnetic ngokuvamile kusebenzisa ukuhlukaniswa kwamagnetic okumanzi okunamandla, okungokwendlela yokuzuza ngokomzimba, ukuvikelwa kwemvelo kanye nokungabi nokungcola, futhi kufanelekile ukususwa kwensimbi kanye nokuhlanzwa kwe-feldspar ore yezakhiwo ezahlukahlukene. Izimo ezithile ezifana nezici ezifakiwe kanye nosayizi wezinhlayiya ezikhethiwe zikhethwa ngamandla ensimu ahlukene kanye nemishini yokuhlukanisa yamagnetic yokuhlunga, kodwa amandla ensimu yamagnetic ngokuyisisekelo ayadingeka ukuba abe ngaphezu kwe-1.0T.
Isihlukanisi semagnethi se-electromagnetic slurry high gradient
Yakha izinqubo ezifanele zokuzuza i-ore ye-feldspar yezakhiwo ezahlukene: kwi-ore ye-feldspar yohlobo lwe-pegmatite, izinhlayiya zekristalu yamaminerali zinkulu futhi kulula ukuzihlukanisa. , umphumela wokuzuza muhle futhi unobungani nemvelo; kwi-feldspar enokuqukethwe okuphezulu kwe-quartz, inqubo ehlanganisiwe yokuhlukaniswa okunamandla kwe-magnetic kanye ne-flotation isetshenziswa kakhulu, okungukuthi ukuchoboza-ukugaya-ukuhlukaniswa-okunamandla kwe-magnetic separation-flotation. Ukuhlukaniswa kwe-magnetic kuqala kususa ukungcola kwe-magnetic njenge-iron oxide ne-biotite, bese kusebenzisa i-flotation ukuhlukanisa i-feldspar ne-quartz ukuthola imikhiqizo emibili esezingeni eliphezulu. Izinqubo ezimbili zokuzuza ezingenhla zifeze umgomo wokwenza kube lula kanye nokusebenza kahle kakhulu ekuzuzeni i-ore ye-feldspar, futhi zikhuthazwe kabanzi futhi zasetshenziswa.
