Ka faa'iidaysiga dhamaystiran ee dabo-dabooreedka ayaa ah eray aad u kulul dhinaca macdanta sannadihii la soo dhaafay, waxaana sidoo kale la sameeyay cilmi-baadhis ku saabsan isticmaalka dhammaystiran ee dabada dahabka ah. Waxaa la fahamsan yahay in wax soo saarka dabada dahabka ah ee dalkaygu uu gaadhay in ka badan 1.5 bilyan oo tan, laakiin isticmaalka dhamaystiran ee isticmaalka ayaa ka yar 20%. Dabada miinadu waxay ka kooban tahay laba siyaabood: buuxinta dhulka hoostiisa iyo ka faa'iidaysiga kheyraadka. Habka buuxinta dhaqameed ee macdanta dahabka ayaa ah in lagu buuxiyo dabo aan dhab ahayn oo ceelka ah, halka dabo yaryar ay ku urursan yihiin balli dabo ah. Sababtoo ah waxa ku jira dahabka Macdanta sida caadiga ah way yar tahay, si loo kordhiyo helitaanka kheyraadka dahabka, badanaa waa lagama maarmaan in la sameeyo hawlgallo shiidis ah. Sidaa darteed, dabo yaryar oo jilicsan ayaa ka kooban waxyaabo badan, halka dabo-dhabarka-yar-yar-yar-yar, oo kaliya oo kaliya oo daboolan oo daboolan ay ka buuxaan dhulka hoostiisa. , suurtagal maaha in aasaas ahaan la yareeyo qashinka adag lana yareeyo awoodda kaydinta balliyada dabada. Haysashada balliyada dabada ayaa wali u baahan dhul badan waxayna waxyeelo u geysataa deegaanka
February 10, 2022, Wasaaradda Warshadaha iyo Tignoolajiyada, Komishanka Horumarinta iyo Dib-u-habaynta Qaranka, Wasaaradda Sayniska iyo Tignoolajiyada, Wasaaradda Maaliyadda, Wasaaradda Khayraadka Dabiiciga ah, Wasaaradda Deegaanka iyo Deegaanka, Wasaaradda Ganacsiga. , iyo Maamulka Canshuuraha ee Gobolka ayaa si wadajir ah u soo saaray "Daabacaadda iyo Qaybinta Dar-dargelinta Horumarinta Kheyraadka Warshadaha". "Ogaysiis ku saabsan Qorshaha hirgelinta ee ka faa'iidaysiga dhamaystiran" wuxuu u baahan yahay in 2025, xoojinta soo saarista qashinka adag ee warshadaha ee warshadaha muhiimka ah sida birta iyo birta, biraha aan birta ahayn, iyo warshadaha kiimikaad ee dalkaygu way yaraan doonaan, heerka isticmaalka dhamaystiran Inta badan qashinka adag ee warshadaha ayaa si weyn loo wanaajin doonaa, warshadaha kheyraadka la cusboonaysiin karo waxay sii wadi doonaan inay si caafimaad leh u horumaraan, ilaha warshadahana si buuxda ayaa looga faa'iidaysan doonaa. Waxtarka si weyn ayaa loo hagaajiyay, heerka isticmaalka guud ee qashinka adag ee warshadaha ayaa gaari doona 57%.Sidaa darteed, ka faa'iidaysiga kheyraadka dabada dahabka ah waa lama huraan.
Shaybaadhka muhiimka ah ee Sino-Jarmalka ee Magnetoelectricity iyo farsamaynta macdanta caqliga leh ee Shirkadda Huate waxay qabataa tiro badan oo tijaabooyin ka faa'iidaysi ah oo ku saabsan dabada dahabka ah ee aagga Yantai. Qaybaha macdanta ugu muhiimsan ee dabada dahabka ah waa macdanta gangue sida quartz, feldspar iyo calcite, iyo qadar yar oo birta farsamada, birta magnetic, birta oxide, titanium oxide, silicate birta, birta sulfide iyo wasakh kale. dabada dahabka ah guud ahaan waa 200 mesh 50-70%, cabbirka qaybtu waa lebis, waxaana ku jira qadar yar oo dhoobo ah. Waxa ugu weyn ee wasakhda ah ee Fe2O3 waa 1-3%, TiO2 waxa ku jira 0.1-0.3%, CaO waxa ku jira 0.12-1.0%, cadaanka dabada dahabka ahna waa 5-20%. Waxaa jira kala duwanaansho gaar ah oo ka kooban halabuurka dabada oo ay soo saaraan xog-ururinno kala duwan. Qaar ka mid ah dabada ayaa leh maaddooyin SiO2 ah oo sarreeya, ama waxaa ku jira spodumene, sericite, iwm. Intooda badan waxay ka tirsan yihiin nooca feldspar-quartz nooca pegmatite, oo leh qiime sare oo dib u isticmaalka ah.
Shirkadda Huate waxa ay ikhtiraacday "Magnetic Separation-Sparation-cuf-cuf-isjiideed" geeddi-socodka faa'iidada isku dhafan, waxayna heshay oggolaanshaha ikhtiraacida hal-abuurka Sebtembar 2020. Nuxurka shatigu wuxuu ku saabsan yahay "habka faa'iidaysiga dhamaystiran ee dabada dahabka ah ee ka kooban dahab, birta iyo feldspar. Hadda, in ka badan Toban codsi oo waaweyn oo warshado ah ayaa lagu fuliyay Yantai, Shandong, oo ah kan ugu weyn kaas oo farsamayn kara 8,000 tan oo dabo dahab ah maalintii. Nidaamkan, qalabka ka faa'iidaysiga horumarsan sida shaashadda gariir, chute spiral, miis gariiraya, durbaan magnetic SEPARATOR. , kala saara saxan magnet xoog qoyan, giraanta toosan sare gradient magnetic, iyo kala qaybiyaha magnetic slurry electromagnetic ayaa la isku daray. Iyadoo la helayo feldspar tayo sare leh oo xoogga saaraysa dabada, alaabooyinka qiimaha leh sida magnetite, macdanta dahabka leh, alaabta ceeriin ee sibidhka, iyo alaabta ceeriin-samaynta ayaa sidoo kale dib loo soo ceshadaa si loo xaqiijiyo isticmaalka dhamaystiran ee dabada dahabka ah iyo in la gaaro dheecaan eber ah dhammaantiis. -dariiqa wareegsan.
Kala soocida magnetic gradient sare giraanta taagan iyo korantada slurry gradient magnetic sare waxaa loo isticmaalaa mashruuca dabada dahabka ah
