Ezinsukwini ezimbalwa ezedlule, kwathunyelwa izindaba ezinhle ezivela emhlanganweni wokuhlola impumelelo yesayensi nezobuchwepheshe we-“Key Technology Research and Industrial Application of Refractory Iron Oxide Ore Suspension Magnetization Roasting” owawubanjwe yi-Gansu Institute of Metals: Ubuchwepheshe obuphelele bempumelelo yesayensi nezobuchwepheshe bufinyelele ezingeni eliphambili lamazwe ngamazwe, futhi kunconywa ukusheshisa ukukhushulwa kanye nokusetshenziswa.

I-ore yokuqala ye-Jingtieshan Mine yase-JISCO inezinga eliphansi lensimbi, izinhlobo eziningi zamaminerali aphethe insimbi, ubudlelwano obuyinkimbinkimbi be-symbiosis kanye nokuqukethwe okuphezulu kokungcola. Ingowe-ore ejwayelekile ye-iron oxide ephikisayo e-China. Inqubo yendabuko yokuzuza inezinga eliphansi lokubuyisa insimbi kanye nekhwalithi embi yokugxila. , Okuthinta izinzuzo zezomnotho zamabhizinisi, futhi ayikwazi ukuhlangabezana nezidingo ze-Jiuquan Steel zokuthuthukisa ikhwalithi nokusebenza kahle, ukuguqulwa nokuthuthukiswa, kanye nentuthuko yekhwalithi ephezulu.

Ukuze kuthuthukiswe ukusebenza kahle kokusetshenziswa kwezinsiza, iJiugang Group ibambisene neNortheastern University, iShenyang Xinbo Industrial Technology Co., Ltd. kanye namanye amayunithi ukuthuthukisa ubuchwepheshe bokugcaba ngemagnetization yokumiswa kwe-iron oxide ore engaphikisi, futhi yatshala imali ekwakhiweni kwe-suspension enekhono lokucubungula laminyaka yonke lamathani ayizigidi eziyi-1.65 e-ore eluhlaza. Umugqa wokukhiqiza we-magnetized roasting and beneficiation waqala ukusebenza ngokusemthethweni ngoNovemba 21, 2020, futhi wafinyelela ekukhiqizweni okugcwele kanye nokuhambisana nomthetho ngoJuni 25 kulo nyaka. Uma kuqhathaniswa nenqubo yokuqala yokuhlukanisa i-magnetic enamandla, izinga lensimbi le-concentrate landa ngo-12%, kanti izinga lokubuyisa insimbi landa ngo-26%. Umphumela ubaluleke kakhulu.

Emhlanganweni wokuhlola, ochwepheshe abayisikhombisa okubalwa kubo uSun Chuanyao, isazi se-Chinese Academy of Engineering, balalele imibiko, babukeza izinto zokwakha, futhi baxoxa ngemibuzo, begxile ezingeni lokusungula izinto ezintsha kwezobuchwepheshe, izinga elithuthukile lezinkomba zobuchwepheshe nezomnotho, ubunzima bobuchwepheshe kanye nobunzima, ukukhiqizwa kabusha kobuchwepheshe kanye nokuvuthwa, ukusungula izinto ezintsha kwezobuchwepheshe kuhlole ngokucophelela imiphumela ezicini eziyisithupha, okuhlanganisa indima yokukhuthaza intuthuko yezobuchwepheshe embonini kanye nokuthuthukisa ukuncintisana kwemakethe, izinzuzo zezomnotho noma zomphakathi, kanti imibono yokugcina yokuhlola isivele yakhiwe. Ochwepheshe bokuhlola bakholelwa ukuthi impumelelo yesayensi nezobuchwepheshe eqediwe yiJiuquan Steel Group kanye namanye amayunithi inezinga eliphezulu lokusungula izinto ezintsha kwezobuchwepheshe. Umugqa wokuqala wokukhiqiza ukuthosa nokuzuza kwasekhaya nakwamanye amazwe omiswe ngogesi one-magnethi yokucutshungulwa kwamathani ayizigidi eziyi-1.65 e-fine ore unezinkomba zobuchwepheshe ezithuthukisiwe futhi waxazulula i-iron ore eyinkimbinkimbi futhi enzima ukuyilungisa. Inkinga yokusetshenziswa kahle kwezinsizakusebenza ikhuthaze kakhulu intuthuko yezobuchwepheshe yemboni yokuhlinzeka nge-iron ore. Ngenxa yobunzima bemvelo ye-ore ye-Jiuquan Iron and Steel, i-Jiuquan Iron and Steel Group kanye nezinye izingxenye zokuphothula impumelelo yephrojekthi zihlole futhi zasebenza ngenkuthalo, zaxazulula uchungechunge lwezinkinga zobuchwepheshe ekusetshenzisweni kwezimboni kobuchwepheshe bokugcaba ngemagnetization, futhi zathola ukusebenza okuzinzile futhi yonke inqubo yafinyelela amazinga okukhiqiza. Yonke inqubo Ubuchwepheshe bunzima futhi buyinkimbinkimbi. Kuze kube manje, umugqa wokukhiqiza ubusebenza kahle unyaka owodwa, ngokuvuthwa okuphezulu kobuchwepheshe kanye nokuqashelwa kabusha, okunikeza ukwesekwa kobuchwepheshe ekuxazululeni ngokuphelele inkinga yokusetshenziswa kahle kwezinsizakusebenza ze-iron oxide ore ezingaphikisi, futhi kuthuthukisa ukuncintisana okuyinhloko kwebhizinisi. Ukukhishwa kwegesi yomoya ongcolile kufinyelela ezithandweni zezimboni zesifundazwe saseGansu kudinga ukwelashwa okujulile, okunezinzuzo ezibalulekile kwezomnotho, kwezenhlalo kanye nezemvelo.

Kuyaqondakala ukuthi phakathi nesikhathi "se-14th Five-Year Plan", i-Jiu Steel Group, ngokusekelwe ezinzuzweni zayo zezinsiza kanye nezici zezinsiza ezizungezile, izoqhubeka nokukhuthaza amasu aqhutshwa ukusungula izinto ezintsha kanye namasu okuqinisekisa izinsiza, ikhuthaze ukusetshenziswa kobuchwepheshe bokugcaba ngemagnetization, futhi yakhe insimbi esebenza kahle, ezinzile futhi ehlukahlukene. Uhlelo lokuqinisekisa izinsiza zamaminerali lunikeza ukwesekwa okuqinile kwamabhizinisi ukuqinisa isisekelo sawo sezimboni, ukwakha kabusha izinzuzo zawo zokuncintisana, kanye nokubamba indawo ephakeme yentuthuko.
