Ukusetshenziswa okuphelele kwezinsalela kuyigama elishisayo emkhakheni wezimayini eminyakeni yamuva nje, futhi ucwaningo mayelana nokusetshenziswa okuphelele kwezinsalela zegolide selwenziwe. Kuyaqondakala ukuthi ukukhiqizwa kwezinsalela zemayini yegolide ezweni lami sekufinyelele amathani angaphezu kwezigidigidi eziyi-1.5, kodwa izinga eliphelele lokusetshenziswa lingaphansi kwama-20%.Okwamanje, indlela ekahle kakhulu yokuthola ukulahlwa kwegolide okungenadoti nokungenangozi. imisila yezimayini ihlanganisa izindlela ezimbili: ukugcwaliswa ngaphansi komhlaba kanye nokusetshenziswa kwezinsiza.Inqubo yendabuko yokugcwalisa izimayini zegolide iwukugcwalisa izinsalela ezinohlamvu olumahhadla emthonjeni, kuyilapho izinsalela ezisanhlamvu zinqwabelana echibini lemisila.Ngenxa yokuthi okuqukethwe yigolide insimbi ngokuvamile iphansi, ukuze kwandiswe ukutholwa kwezisetshenziswa zegolide, ngokuvamile kuyadingeka ukwenza imisebenzi yokugaya. Ngakho-ke, ama-tailings-grained tailings aqukethe okuningi, kuyilapho i-tailing-grained tailings incane, futhi kuphela i-tailing-grained tailings igcwaliswa ngaphansi komhlaba. , akunakwenzeka ukunciphisa ngokuyisisekelo imfucuza eqinile futhi unciphise umthamo wokugcina wamachibi ama-tailings. Ukugcina amachibi ensila kusadinga umhlaba omningi futhi kulimaza imvelo.Ukulahlwa kwezinsalela zegolide sekuyimbangela enkulu evimbela ukuthuthukiswa komnotho esimeme ezimayini zegolide.
Ngomhla ziyi-10 kuFebruwari, 2022, uMnyango Wezimboni Nobuchwepheshe Bolwazi, Ikhomishini Kazwelonke Yokuthuthukiswa Nezinguquko, Umnyango Wesayensi Nobuchwepheshe, Umnyango Wezezimali, Umnyango Wezemvelo, Umnyango Wezemvelo Nemvelo, Umnyango Wezohwebo. , kanye Nokuphathwa Kwentela Kwezwe ngokuhlanganyela kukhiphe “Ekuphrinteni Nokusabalalisa Okusheshisa Ukuphromothwa Kwezinsiza Zezimboni”. “Isaziso Sohlelo Lokusebenza Lokusetshenziswa Okuphelele” sidinga ukuthi ngo-2025, umfutho wokuphehlwa kukadoti oqinile ezimbonini ezimbonini ezibalulekile ezifana nensimbi nensimbi, izinsimbi ezingenayo insimbi, kanye nezimboni zamakhemikhali ezweni lami kuzokwehla, izinga lokusebenzisa okuphelele. inqwaba yemfucuza eqinile yezimboni izothuthukiswa kakhulu, imboni yezinsiza ezivuselelekayo izoqhubeka nokuthuthuka ngendlela enempilo, kanye nezinsiza zezimboni zizosetshenziswa ngokuphelele. Ukusebenza kahle kuye kwathuthukiswa kakhulu, futhi izinga eliphelele lokusebenzisa inqwaba yemfucuza eqinile yezimboni lizofinyelela ku-57%.Ngakho-ke, ukusetshenziswa kwezinsiza zezinsalela zegolide kubalulekile.
I-Sino-German Key Laboratory ye-Magnetoelectricity and Intelligent Mineral Processing ye-Huate Company yenza inani elikhulu lezivivinyo zokuhlomula ezinsaleni zegolide endaweni yase-Yantai. Izingxenye eziyinhloko zamaminerali emisila yegolide amaminerali e-ganggue afana ne-quartz, i-feldspar ne-calcite, kanye nenani elincane le-Iron engumshini, insimbi kazibuthe, i-iron oxide, i-titanium oxide, i-iron silicate, i-iron sulfide nokunye ukungcola. igolide tailings ngokuvamile 200 anezikhala 50-70%, usayizi kuyizinhlayiyana iyunifomu kuqhathaniswa, futhi iqukethe inani elincane lodaka olucolekile. Ukungcola okuyinhloko okuqukethwe kwe-Fe2O3 ngu-1-3%, okuqukethwe kwe-TiO2 kungu-0.1-0.3%, okuqukethwe kwe-CaO ngu-0.12-1.0%, kanti ubumhlophe bemisila yegolide ngu-5-20%. Kukhona umehluko othile ekubunjweni kwemisila ekhiqizwa ama-concentrator ahlukene. Eminye imisila inokuqukethwe okuphezulu kwe-SiO2, noma iqukethe i-spodumene, i-sericite, njll. Eziningi zazo zingezohlobo lwe-feldspar-quartz yohlobo lwe-pegmatite, enenani eliphezulu lokuphinda lisetshenziswe.
Inkampani yakwa-Huate isungule "indlela kazibuthe yokuhlukanisa-ukuhlukaniswa kwamandla adonsela phansi" inqubo ehlanganisiwe yokuhlomula, futhi yathola ukugunyazwa kwelungelo lobunikazi ngo-September 2020. Okuqukethwe kwelungelo lobunikazi kumayelana "nendlela yokusetshenziswa okuphelele kwezinsalela zegolide eziqukethe igolide, insimbi ne-feldspar. Okwamanje, ngaphezu kwalokho, ngaphezu kwalokho izicelo zezimboni ezinkulu eziyishumi zenziwe eYantai, eShandong, enkulu kunazo zonke ekwazi ukucubungula amathani angu-8,000 emisila yegolide ngosuku.Kule nqubo, imishini ethuthukisiwe yokuzuza njengesikrini esidlidlizayo, i-spiral chute, itafula elinyakazayo, isihlukanisi sogubhu kazibuthe. , isihlukanisi sikazibuthe esiqinile esimanzi esiqinile, isihlukanisi esiqondile esiyindandatho esime mpo esiphezulu sikazibuthe, kanye nesihlukanisi esinodaka kazibuthe sikagesi sisetshenziswa ngokuhlanganyela. Ngenkathi kutholwa ukugxilwa kwekhwalithi ephezulu kwe-feldspar kumasisila, imikhiqizo ebalulekile efana ne-magnetite, amaminerali anegolide, izinto zokusetshenziswa zikasimende, nezinto ezingavuthiwe zokwakha izitini nazo ziyatholwa ukuze kubhekwe ukusetshenziswa okuphelele kwezinsalela zegolide futhi kukhishwe iqanda ngokuphelele. - indlela ejikelezayo.
Isihlukanisi esime mpo se-gradient high gradient magnetic kanye ne-electromagnetic slurry high gradient separator kazibuthe zisetshenziswa kuphrojekthi yomsila wegolide.
