Tšebeliso e felletseng ea li-tailings ke lentsoe le chesang lefapheng la merafo lilemong tsa morao tjena, 'me lipatlisiso mabapi le tšebeliso e felletseng ea li-tailings tsa khauta le tsona li entsoe. Hoa utloisisoa hore tlhahiso ea li-tailings tsa merafo ea khauta naheng ea heso e fihlile ho lithane tse fetang limilione tse likete tse 1.5, empa sekhahla se felletseng sa tšebeliso se ka tlase ho 20%. Hona joale, tsela e ntle ka ho fetisisa ea ho phethahatsa ho lahla li-tailings tsa merafo ea khauta ntle le litšila le ho se kotsi ho kenyelletsa litsela tse peli: ho tlatsa ka tlas'a lefatše le tšebeliso ea mehloli. Mokhoa oa setso oa ho tlatsa merafo ea khauta ke ho tlatsa li-tailings tse nang le likhoele tse khorofo ka selibeng, ha li-tailings tse nang le likhoele tse khorofo li bokellana ka letamong la li-tailings. Hobane bokaholimo ba oli ea khauta hangata bo tlase, e le ho eketsa ho fumanoa ha mehloli ea khauta, hangata ho hlokahala ho etsa ts'ebetso ea ho sila. Ka hona, li-tailings tse nang le likhoele tse khorofo li na le tse ngata, ha li-tailings tse nang le likhoele tse khorofo li le nyane, 'me ke li-tailings tse khorofo feela tse tletseng ka tlas'a lefatše. , ho ke ke ha khoneha ho fokotsa litšila tse tiileng le ho fokotsa bokhoni ba polokelo ea matamo a li-tailings. Matamo a ho boloka mesaletsa ea khauta a ntse a hloka mobu o mongata 'me a senya tikoloho. Ho lahla mesaletsa ea khauta e se e le ntlha e kholo e thibelang nts'etsopele ea moruo e tsitsitseng ea merafo ea khauta.
Ka la 10 Hlakola 2022, Lefapha la Indasteri le Theknoloji ea Tlhahisoleseling, Khomishene ea Naha ea Ntšetso-pele le Ntlafatso, Lefapha la Saense le Theknoloji, Lefapha la Lichelete, Lefapha la Lisebelisoa tsa Tlhaho, Lefapha la Tikoloho le Tikoloho, Lefapha la Khoebo, le Tsamaiso ea Naha ea Lekhetho ba fane ka tumellano ea "Mabapi le ho Hatisa le ho Atolosa Khothaletso ea Lisebelisoa tsa Indasteri". "Tsebiso mabapi le Morero oa Ts'ebetsong oa Tšebeliso e Felletseng" e hloka hore ka 2025, matla a tlhahiso ea litšila tse tiileng tsa indasteri liindastering tsa bohlokoa tse kang tšepe le tšepe, litšepe tse se nang ferrous, le liindasteri tsa lik'hemik'hale naheng ea heso li fokotsehe, boemo bo felletseng ba tšebeliso ea litšila tse tiileng tsa indasteri bo ntlafalitsoe haholo, indasteri ea lisebelisoa tse nchafatsoang e tla tsoela pele ho hola hantle, 'me lisebelisoa tsa indasteri li tla sebelisoa ka botlalo. Bokgoni bo ntlafalitsoe haholo, 'me sekhahla se felletseng sa tšebeliso ea litšila tse tiileng tsa indasteri tse ngata se tla fihla ho 57%. Ka hona, tšebeliso ea lisebelisoa tsa mesaletsa ea khauta ea bohlokoa.
Laboratori ea Bohlokoa ea Sino-German ea Magnetoelectricity le Intelligent Mineral Processing ea Huate Company e etsa liteko tse ngata tsa ho ntlafatsa mehele ea khauta sebakeng sa Yantai. Likarolo tse ka sehloohong tsa mehele ea khauta ke liminerale tsa gangue tse kang quartz, feldspar le calcite, le karolo e nyane ea Tšepe ea mechini, tšepe ea makenete, oxide ea tšepe, titanium oxide, silicate ea tšepe, sulfide ea tšepe le litšila tse ling. Boholo ba mehele ea khauta ka kakaretso ke 200 mesh 50-70%, boholo ba mehele bo batla bo lekana, 'me bo na le seretse se senyenyane se setle. Sekoli se seholo sa Fe2O3 ke 1-3%, sekoli sa TiO2 ke 0.1-0.3%, sekoli sa CaO ke 0.12-1.0%, 'me bosoeu ba mehele ea khauta ke 5-20%. Ho na le liphapang tse itseng sebopehong sa mehele e hlahisoang ke li-concentrator tse fapaneng. Metswako e meng e na le dikahare tse hodimo tsa SiO2, kapa e na le spodumene, sericite, jj. Bongata ba yona ke ya mofuta wa pegmatite wa feldspar-quartz, o nang le boleng bo hodimo ba ho sebediswa hape.
Khamphani ea Huate e qapile mokhoa oa ho kopanya oa ho rua molemo o kopantsoeng oa "karohano ea makenete le matla a khoheli", 'me ea fumana tumello ea patent ea tlhahiso ka Loetse 2020. Litaba tsa patent li mabapi le "mokhoa o felletseng oa tšebeliso ea li-tailings tsa khauta tse nang le khauta, tšepe le feldspar. Hona joale, lits'ebetso tse kholo tsa indasteri tse fetang leshome li se li entsoe Yantai, Shandong, e kholo ka ho fetisisa ea tsona e ka sebetsanang le lithane tse 8,000 tsa li-tailings tsa khauta ka letsatsi. Ts'ebetsong ena, lisebelisoa tse tsoetseng pele tsa ho rua molemo tse kang skrine e thothomelang, chute ea spiral, tafole e thothomelang, karohano ea makenete ea drum, karohano ea makenete ea poleiti e matla ea makenete, karohano ea makenete ea vertical ring high gradient, le karohano ea makenete ea slurry ea electromagnetic slurry lia sebelisoa hammoho. Ha ho ntse ho fumanoa motsoako oa feldspar oa boleng bo holimo ho tsoa li-tailings, lihlahisoa tsa bohlokoa tse kang magnetite, liminerale tse nang le khauta, thepa e tala ea samente le thepa e tala ea ho etsa litene le tsona lia fumanoa ho phethahatsa ts'ebeliso e felletseng ea li-tailings tsa khauta le ho fihlela ho se ntšehe ka tsela e akaretsang.
