Ka faa'iidaysiga dhamaystiran ee dabo-dabooreedka ayaa ah erey aad u kulul dhinaca macdanta sannadihii u dambeeyay, waxaana sidoo kale la sameeyay cilmi-baaris ku saabsan isticmaalka dhamaystiran 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 guud 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-cagaaran oo yaryar ayaa ka kooban wax badan, halka dabo-dabo-yar-yar-yar-yar-yar-yar-yar-yar-yar-yar-yar-yareedka ah, oo kaliya oo kaliya oo daboolan oo daboolan ayaa ka buuxa dhulka hoostiisa., suurtagal maaha in aasaas ahaan la yareeyo qashinka adag oo la 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 2025, xoojinta soo saarista qashinka adag ee warshadaha ee warshadaha muhiimka ah sida birta iyo birta, biraha aan birta ahayn, iyo warshadaha kiimikada 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 doontaa inay si caafimaad leh u horumarto, iyo agabka warshadaha si buuxda ayaa looga faa'iidaysan doonaa.Waxtarka si weyn ayaa loo hagaajiyay, iyo heerka ka faa'iidaysiga guud ee qashinka adag ee warshadaha wuxuu gaari doonaa 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 qaybuhu waa lebbis, 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 maado 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 isticmaal ah.
Shirkadda Huate waxay ikhtiraacday "kala-soocidda-cafis-is-jiidad-magnetic" habka faa'iidada isku dhafan, waxayna heshay oggolaanshaha ikhtiraacida ikhtiraacida Sebtembar 2020. Nuxurka shatigu wuxuu ku saabsan yahay "habka faa'iidaysiga dhamaystiran ee dabada dahabka ah oo ka kooban dahab, bir iyo feldspar. Hadda, in ka badan Toban codsi oo waaweyn oo warshado ah ayaa lagu fuliyay Yantai, Shandong, kan ugu weyn kaas oo farsamayn kara 8,000 tan oo dabo dahab ah maalintii. Habkan, qalabka ka faa'iidaysiga horumarsan sida shaashadda gariir, chute spiral, miis gariir, durbaan magnetic SEPARATOR. , kala saara saxan magnetic xoog qoyan, giraanta toosan sare gradient magnetic SEPARATOR, iyo electromagnetic slurry magnetic separator waxaa loo isticmaalaa isku darka.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
