I-Feldspar iyiminerali ye-aluminosilicate yezinsimbi ze-alkali nezinsimbi zomhlaba ezine-alkali ezifana ne-potassium, i-sodium ne-calcium. Inomndeni omkhulu futhi iyiminerali evame kakhulu yokwenza amadwala. Kwenzeka kakhulu emadwaleni e-magmatic ahlukahlukene kanye namadwala e-metamorphic, okulinganiselwa ku-50% wengqikithi ye-crust, lapho cishe u-60% we-feldspar ore etholakala emadwaleni amakhulu. Imayini ye-feldspar ngokuyinhloko yenziwe nge-potassium ne-albite ecebile nge-potassium noma i-sodium, futhi ukuthuthukiswa kwayo ku-ceramics, imboni yezempi, imboni yamakhemikhali, ukwakhiwa kanye nezinye izimboni yiyona "amandla amakhulu". imboni ukukhiqiza imikhiqizo yengilazi efana nengilazi eyisicaba, i-glassware kanye ne-glass fiber; okwesibili, isetshenziswa njengento eluhlaza ye-ceramics kanye ne-glaze ukukhiqiza amathayela odongeni, izitsha zamakhemikhali, izitsha zobumba zikagesi kanye nezinsimbi zokugaya; isetshenziswa ikakhulukazi njengezinto zokusetshenziswa zamakhemikhali zokukhiqiza iRubber nepulasitiki yokugcwalisa kanye nokukhiqizwa komanyolo wamakhemikhali, njll.; lapho isetshenziswa njengezinto zokwakha, ikhiqiza ikakhulukazi usimende okhethekile kanye nemicu yengilazi.
Ngemva kokukhululwa “koHlelo Lweminyaka Emihlanu Lwezimayini Ezingezona Zensimbi kanye Nombono wezi-2035”, “Uhlelo” lufinyeza impumelelo emihle kanye nezinkinga zokuthuthukiswa “koHlelo Lweminyaka Eyi-13 Lweminyaka Emihlanu”; ihlaziya indawo yentuthuko kanye nesidingo semakethe, futhi iphakamisa imibono Emisha eyisiqondiso, izimiso eziyisisekelo zokuthuthukiswa, kanye nemigomo eyinhloko yakhiwe, futhi imisebenzi ebalulekile, amaphrojekthi abalulekile nezindlela zokuvikela ziye zacaciswa.
Imboni yezimayini ezingezona ezensimbi ilwela ukusebenzisa umqondo omusha wentuthuko, ibambe ngokuqinile ithuba lesu lokuthi ukuthuthukiswa komnotho wezwe lami kungena entuthukweni yezinga eliphezulu, icwaninge futhi ibhale “Imibono Eholayo Ekuthuthukiseni Intuthuko Esezingeni Eliphezulu Yezingezona Zensimbi. Imboni Yezimayini”, futhi ihlongoza ukuthuthukiswa kwekhwalithi ephezulu kwezici zemboni, izinjongo zomsebenzi, izimiso eziyisisekelo kanye nezivikelo;Hlela ukuhlanganiswa kwe-“Non-metallic Mining Industry Technology Development Roadmap” ka-2021-2035, lungisa futhi ucacise izidingo zentuthuko. , izinto ezibalulekile zentuthuko, amaphrojekthi amakhulu kanye nemiklamo yemiboniso yobuchwepheshe bezimayini obungezona ezensimbi ngezigaba, kanye nokuthuthukisa isiqondiso nenjongo yokusungula izinto ezintsha zesayensi nezobuchwepheshe embonini; Ukuhlela ukwakhiwa “koHlelo Lokusebenza Lokucwaninga Okusha kanye Nokuthuthukiswa Kobuchwepheshe Nezisetshenziswa Zesizukulwane Esisha Embonini Yezimayini Ezingeyona Insimbi”, futhi kubekwe phambili izinjongo nemisebenzi yocwaningo olusha kanye nokuthuthukiswa kwesizukulwane esisha sokumbiwa phansi okungeyona insimbi. ubuchwepheshe kanye nemishini.
Ukupholisa okuyinhlanganisela yamanzi kawoyela iringi ethe mpo mpo isihlukanisi kazibuthe
Yabhalwa yi-China Non-metallic Mining Industry Association, futhi uMnyango Wezemvelo wakhipha futhi wasebenzisa izinga elithi “Izicaciso Zokwakhiwa Kwezimayini Eziluhlaza Embonini Yezimayini Ezingezona Zensimbi”. izici ezibalulekile “zokwenziwa kwemishini” kanye “nokukhiqizwa komkhiqizo” kwenziwe, okukhuthaze ukuthuthukiswa okujulile kokukhiqizwa okukhaliphile embonini yezimayini engeyona eyensimbi. Kuhlelwe futhi kwenziwa ucwaningo ngobuchwepheshe obusha kanye nezinqubo ezintsha ezifana nobuchwepheshe bokucubungula obujulile obungenasisila, ubuchwepheshe bokuchotshozwa okomile kanye nokuhlanza, kanye nokulungiswa kwezinto ezivuvukalayo ezivela kumaminerali e-silicate; ithuthukiswe ngempumelelo izihlukanisi ezinozibuthe ezinkulu ezinkulu, izihlukanisi kazibuthe ezinkulu ezisebenza ngamandla amakhulu, i-ultra enkulu Isethi ephelele yemigqa yokukhiqiza yokuchotshozwa, ukugreda okuhle nokuguqulwa, abahlaziyi besistimu yokuma kwezinhlayiyana ezinembayo nezinye izinsimbi ezintsha nemishini emisha.
I-China yizwe elinezinsiza ezinkulu ze-feldspar ore. Izinqolobane ze-feldspar ore zamabanga ahlukahlukene zingamathani ayizigidi ezingama-40.83. Iningi lamadiphozithi amadiphozithi e-pegmatite, okuyizinhlobo eziyinhloko zamadiphozithi akhiwe futhi asetshenziswa njengamanje. Ngokusho kwe-China Building Materials Industry Standard (JC/T-859-2000), i-feldspar ore ihlukaniswe izigaba ezimbili (i-potassium feldspar, i-albite) namabanga amathathu (umkhiqizo ophakeme, umkhiqizo wezinga lokuqala, umkhiqizo oqeqeshiwe). E-Anhui, Shanxi, Shandong, Hunan, Gansu, Liaoning, Shaanxi nakwezinye izindawo.
Ngokusho kokuqukethwe kwe-potassium, i-sodium, i-silicon nezinye izakhi, ukusetshenziswa okuyinhloko kwamaminerali e-feldspar nakho kuhlukile. Izindlela zokuhlomula ze-Feldspar ikakhulukazi zihlukanisa kazibuthe kanye nokuntanta. Ukuhlukaniswa kwamagnetic ngokuvamile kusebenzisa ukuhlukaniswa kukazibuthe okumanzi okumanzi, okungokwenzuzo yendlela yomzimba, ukuvikelwa kwemvelo nokungangcoli, futhi kulungele ukukhishwa kwensimbi nokuhlanzwa kwe-feldspar ore yezakhiwo ezihlukahlukene. Izimo ezithile ezifana nezici ezishumekiwe nosayizi wezinhlayiyana ezikhethiwe zikhethwa amandla enkundla ahlukene kanye nemishini yokuhlukanisa kazibuthe ukuze kuhlungwe, kodwa amandla kazibuthe adingeka ngokuyisisekelo ukuze abe ngaphezu kuka-1.0T.
I-electromagnetic slurry high gradient isihlukanisi kazibuthe
Yakha izinqubo zokuhlomula ezifanele ze-feldspar ore yezakhiwo ezahlukene: ku-pegmatite-type feldspar ore, izinhlayiya zekristalu yamaminerali zinkulu futhi kulula ukuzihlukanisa. , umphumela wokuhlomula muhle futhi awuhambisani nemvelo; i-feldspar enokuqukethwe okuphezulu kwe-quartz, inqubo ehlanganisiwe yokuhlukaniswa okuqinile kazibuthe kanye ne-flotation isetshenziswa ngokuyinhloko, okungukuthi i-crushing-grinding-classification-strong magnetic separation-flotation. Ukwehlukanisa kazibuthe kuqala kususa ukungcola kazibuthe njenge-iron oxide ne-biotite, bese kusebenzisa i-flotation ukuhlukanisa i-feldspar ne-quartz ukuze kutholwe imikhiqizo emibili yekhwalithi ephezulu. Lezi zinqubo ezimbili ezingenhla zokuhlomula ziye zafinyelela umgomo wokwenza lula nokusebenza kahle okuphezulu ekuzuzeni i-feldspar ore, futhi ziye zakhuthazwa kabanzi futhi zasetshenziswa.
