I-Magnetite ine-magnetism enamandla, futhi ikakhulukazi ihlanganisa i-single magnetite, i-vanadium-titanium magnetite, i-ore exubile equkethe i-magnetite kanye ne-iron oxide, kanye ne-ore equkethe i-magnetite polymetallic symbiosis. I-Magnetite ihlukaniswe yaba yi-coarse-grained, medium-fine-grained, kanye ne-micro-fine-grained ngokobukhulu bezinhlayiya zayo. Phakathi kwazo, i-iron ore enezinhlamvu ezi-coarse ne-medium-fine ingachotshozwa futhi igaywe ukuze kutholakale i-iron ore concentrate efanelekile ngenqubo yokuhlukanisa i-magnetic ebuthakathaka. I-micro-particle embedded magnetite idinga ukugaywa kahle kuze kube yilapho i-monomer ihlukaniswe ngokuphelele, bese idlula ezinqubweni eziningi zokukhetha ukuze kutholakale izinkomba zokuzuza ezingcono.
Isihlukanisi sikamazibuthe se-JCTN sokulungisa nokunciphisa ukungcoliswa kwe-slag esakhiwe yi-Huate Magnet siyisihlukanisi sikamazibuthe esimanzi esenzelwe ukuhlanza nokuhlanzwa kwe-magnetite. Sifanele ukuhlukaniswa nokususwa kwemikhiqizo yokuchichima yokugaya nokuhlukanisa kwesigaba sokuqala; ngaphambi kokugaya kwesigaba sesibili kanye nokuhlushwa kwamaminerali ngaphambi kokuhlunga; ukususwa kwe-slimi ngaphambi kokuba i-magnetite ingene esihlungweni esihle futhi isuswe ngaphambi kokuntanta okuphambene; ukukhethwa kokugcina kwe-magnetite, okunzima ukuthuthukisa izinga lezinhlayiya ezincane nezinhlayiya ezincane ekuhlukaniseni okujwayelekile kukamazibuthe I-iron ore inomphumela ocacile wokuhlunga.
Ukusetshenziswa kwe-Magnetic Separator yokuhlanza kanye nokunciphisa i-Slag ku-Magnetite ehlungiwe kahle
I-magnetite ecolekile endaweni yaseBenxi ingeye-sedimentary metamorphic lean magnetite. Iminerali eyinhloko yensimbi ye-ore yi-magnetite. Ngokwezakhiwo ze-ore ze-magnetite, inkampani yethu yenze isehlukanisi se-magnetic sokuhlola ukuze kulungiswe futhi kuncishiswe i-slag. Ukuhlolwa kanye namaqoqo emishini yezimboni kuye kwasetshenziswa ekukhiqizweni kwezimboni. Ukusetshenziswa kwangempela kwesehlukanisi se-magnetic sokunciphisa i-slag esicwengisiwe kuye kwanconywa futhi kwaqashelwa amakhasimende. Ngenxa yalesi sizathu, isehlukanisi se-magnetic sokunciphisa i-slag esicwengisiwe sikwazile ukusetshenziswa endaweni yaseBenxi. Sikhuthazwe kakhulu futhi sasetshenziswa. Imininingwane yezimboni esizeni ikhombisa:
1. Ukusebenzisa isihlukanisi sikamazibuthe ukuze kuhlanjululwe futhi kuncishiswe i-slag njengesigaba sokuqala sokuhlukaniswa kukamazibuthe, ngenkathi kuqinisekiswa ukuthi izinga le-tailings alikho ngaphezu kuka-1%, usayizi we-ore yokuqala uyandiswa kusuka ku--200 mesh 80%, kanti izinga licishe libe ngu-28% liye ebangeni le-concentrate elingu-52%. Cishe ngo-14%, isihlukanisi sikamazibuthe esicwengisisiwe esinciphisa i-slag asigcini nje ngokuthuthukisa izinga le-concentrate, kodwa futhi silahla iningi le-tailings, okunciphisa inani lokugaya kwesibili futhi konge ukusetshenziswa kwamandla;
2. Isihlukanisi sikamazibuthe sokucwengisisa nokunciphisa i-slag sisetshenziselwa ukusebenza kokwenza i-beneficiation, kanti usayizi wezinhlayiya ze-ore ungama-mesh angu-600 angu-85%. Uma inkomba yokwenza i-beneficiation ilingana, kungabonakala ukuthi isihlukanisi sikamazibuthe sokucwengisisa kanye nokunciphisa i-slag singathatha indawo yabahlukanisi bakamazibuthe abavamile abaxhunywe ochungechungeni lwezigaba eziningi. Umshini ukhethwa ukuze unciphise ukuhamba kwenqubo futhi ufeze injongo yokunciphisa izindleko nokwandisa ukusebenza kahle.
Izici zobuchwepheshe eziyinhloko zesihlukanisi sikamazibuthe sokuthuthukisa nokunciphisa i-slag
■ Sebenzisa inhlanganisela yedivayisi yokondla ngamapayipi kanye ne-overflow weir ukuze ufeze injongo yokondla ngokulinganayo;
■ Yamukela uhlobo olusha lwesakhiwo lapho umgodi ongezansi kanye nesigubhu kujikeleza khona ngokumelene nokujikeleza, okungakhuphula izinga lokubuyiselwa kwamaminerali;
■ Ithangi elisha elingezansi komfula lihlonyiswe ngokuhlanza okunezigaba eziningi kanye nesakhiwo samakhethini amanzi angaphezulu, okungahlanza ngokuphelele amaminerali ebusweni besigubhu;
■ Ukusebenzisa uhlelo lwe-magnetic olunezinsika eziningi olune-angle enkulu yokugoqa engu-240°-270°, oluhlanganiswe nedivayisi yokuvuselela i-magnetic esilinda, kwenza amaminerali aguqeke futhi axutshwe nge-magnetic, futhi ngaphansi kwesenzo sokuhlanza amanzi, ukungcola okuku-concentrate kususwa ngokuphelele ukuze kuthuthukiswe izinga le-Concentrate.
■ Idivayisi yokukhipha imithwalo isebenzisa isakhiwo sokuklwebha esiphindwe kabili ukuze kutholakale ukugcwala kwamaminerali ngenkathi kukhishwa imithwalo.
Idatha yokusetshenziswa kwesihlukanisi sikamazibuthe sokuthuthukisa nokunciphisa i-slag embonini
1. Isihlukanisi sikamazibuthe sokuhlanza nokunciphisa i-slag sisetshenziselwa isigaba esisodwa sokuhlukaniswa kukamazibuthe
Gaya isampula ye-ore ibe ngu-80% we-mesh engu--200, bese usebenzisa isihlukanisi sikamazibuthe ukuze ucwenge futhi unciphise i-slag ukuze wenze ukuhlukaniswa kukamazibuthe esigabeni sokuqala.
Isihlukanisi sikamazibuthe sokunciphisa ukucwenga kanye nokwehlisa i-slag asigcini nje ngokuthuthukisa izinga lokugxila, kodwa futhi sikhipha iningi lemisila, okunciphisa inani lokugaya kwesibili futhi konga ukusetshenziswa kwamandla. Isihlukanisi sikamazibuthe sokunciphisa i-slag asiqinisekisi nje kuphela ukushelela kokugeleza kwenqubo, kodwa futhi songa nezindleko.
2. Isihlukanisi sikamaginethi sokulungisa kanye nokunciphisa i-slag sisetshenziselwa ukukhetha
Ngenxa yobusha besimiso kanye nesakhiwo sesihlukanisi sikamazibuthe sokuthuthukisa nokunciphisa i-slag, singanciphisa ukugoqa kukamazibuthe futhi sithuthukise izinga lokugxila, ikakhulukazi ku-magnetite enezinhlayiya ezincane.
Ukusetshenziswa kwesihlukanisi sikamazibuthe ukuze kucwengisiswe futhi kuncishiswe i-slag kunomthelela omuhle ekuhlukanisweni kwe-magnetite ehlungwe kahle eBenxi, eLiaoning. Isikhundla sokuhlukaniswa kukamazibuthe esigabeni sokuqala sinyuswe sisuka cishe ku-28% webanga le-ore lokuqala saya cishe ku-52%, okuwukwenyuka okungu-14%. Isihlukanisi sikamazibuthe sokunciphisa i-slag esihle asigcini nje ngokuthuthukisa izinga lokugxila, kodwa futhi sikhipha iningi lemisila, sinciphise inani lokugaya i-ore esigabeni sesibili, futhi sisindisa ukusetshenziswa kwamandla; njengokukhetha, singafeza umsebenzi ojwayelekile wokuhlukaniswa kukamazibuthe othatha indawo yezigaba ezimbili ochungechungeni. , Ngaleyo ndlela kufinyezwe ukugeleza kwenqubo futhi kufezwe injongo yokunciphisa izindleko nokwandisa ukusebenza kahle.
Izicelo
Ukusungula ubuchwepheshe kukaHuate Magneto kungamandla ashukumisayo entuthuko, kugxile ku-R&D kanye nokukhiqizwa kwemishini yokuthuthukisa ephezulu, ubuchwepheshe bamagnethi obusebenzisa i-superconducting kanye nemikhiqizo ye-magnetoelectric yobuchwepheshe obuphezulu yokonga amandla kanye nobungane nemvelo. Ububanzi bezinsizakalo buhlanganisa ukumbiwa kwezimayini, amalahle, amandla kagesi, i-metallurgy, izinsimbi ezingezona i-ferrous, ukuvikelwa kwemvelo, kanye nokwelashwa. Emikhakheni engaphezu kwe-10, sinikeze izixazululo ezilungiselelwe amakhasimende angaphezu kuka-20,000 emhlabeni jikelele. Ngokunamathela emcabangweni wesevisi othi “Amakhasimende ahlala engowokuqala”, inkampani iyaqhubeka nokukhuthaza ukuguqulwa kohlelo lwesevisi, ilwela ukudala izinsizakalo ezilula, ezenzelwe wena uqobo futhi ezenziwe ngokwezifiso kumakhasimende, ihola futhi ikhuthaza ukuguqulwa nokuthuthukiswa kwezinsizakalo zemboni, futhi iba umncintiswano womhlaba wonke. Abahlinzeki bezinsizakalo zesistimu yesicelo samagnetic bayaqhubeka beya phambili!
Le nkampani inelabhorethri kazwelonke yokucubungula amaminerali ehlanganisa indawo engamamitha-skwele ayi-6000, abacwaningi bokuhlola besikhathi esigcwele noma besikhashana abayi-120, imishini yokucubungula yelabhorethri ephelele, amathuluzi okuhlola nokuhlaziya aphelele, izimo ezinhle zokuhlola umkhiqizo, kanye nokuhlolwa okuhlukahlukene. Kunezinqola zemishini nezinsimbi ezingaphezu kuka-200, ezingama-60% zazo ezifinyelele ezingeni eliphambili lasekhaya kanti ezingama-20% zazo zifinyelele ezingeni eliphambili lamazwe ngamazwe. Njengoba ukuthuthukiswa kokukhiqizwa kwemishini yokuhlukanisa amandla kazibuthe kuyindawo yokuqala, kugxilwe ekuthuthukisweni kwama-magnets aqhuba i-superconducting kanye nokwehlukaniswa kwamandla kazibuthe aqhuba i-superconducting emkhakheni wobuchwepheshe bemishini kazibuthe. Ucwaningo ngemishini yobuchwepheshe bezicelo kazibuthe enkulu efana nomshini, i-high-gradient magnetic separator, i-stirrer, njll.
Inkampani yethu ingahlinzeka amakhasimende nezikhungo zocwaningo ngezixazululo eziphelele zenqubo yokuzuza kanye nemishini yokuhlola yokuzuza kusukela ekuchotshozweni, ekuhlolweni, ekuhlukanisweni okomile, ekugayweni, ekuhlukanisweni okubuthakathaka okumanzi okunamandla okunamandla okunamandla, njll., ukuze kuhlinzekwe ukuthi kungenzeka yini ukwakhiwa kwesitshalo sokuzuza. Iseluleko esiqondisayo.
