dhoobo miinshaar ah ayaa isugu jirta budada dhagaxa ah iyo biyaha la soo saaro marka la goynayo laguna sifaynayo marmarka iyo granite.Deegaano badan oo ku yaala waqooyiga dalkeena ayaa ah saldhigyo muhiim ah oo lagu farsameeyo dhagxaanta, waxaana sanad walba la soo saaraa dhoobo aad u badan oo miinshaar ah. kor u kaca dhul ballaaran oo kheyraadka dhulka ah. Budada dhagaxa waxay leedahay muuqaal wanaagsan wayna adagtahay in la tuuro.Way sahlan tahay in cirka lagu duulo iyadoo dabaylo xooggani jirto, waxayna ku qulqulaan webiga iyagoo wata biyaha roobka maalmaha roobka, taasoo keenta wasakh halis ah oo deegaanka ah.
Macdanta gangue ee ugu weyn ee dhoobada lagu arkay waxaa ka mid ah feldspar, quartz, calcite, dolomite, amphibole, iwm. Habka dhoobada miinshaarka ayaa inta badan ah in la soo saaro leben shub ah oo la shiiday oo laga sameeyo alaab ceramik ah ka dib marka laga saaro wasakhda.Kan hore waxa uu leeyahay awood farsamayneed oo ballaadhan, kan dambena waxa uu leeyahay faa'iidooyin dhaqaale oo sarreeya.
Cilmi-baarista faa'iidada
Maqaalkani, isticmaalka dhamaystiran iyo cilmi-baarista faa'iidada faa'iido doonka ah ayaa loo sameeyaa wakiilka dhoobada ee Jining area. Macdanta qiimaha leh ee dhoobada miinshaarka waa feldspar, birta farsamada, birta magnetic, iwm, iyo wasakhda waxyeellada leh waa limonite, biotite, muscovite, calcite, dolomite, hornblende, iwm. Cabbirka maaddadu waa mid aan sinnayn, qaybaha qallafsan waxay u dhexeeyaan 1-4mm iyo qaar ka mid ah -0.037mm dhoobo wanaagsan. macdanta waxa loo kala saari karaa birtu si bir ah.Ka dib kala-soocida bir-labeedka xooggan, wasakhda birta ku jirta sida limonite, biotite, iyo amphibole waa la saari karaa.Alaabooyinka xoogga leh ee dhagxaanta, qayb kasta oo ka mid ah dabada magnetic waxaa loo isticmaali karaa sidii leben hawada laga saaray ama walxaha sibidhka, si loo gaaro ujeedada ka faa'iidaysiga dhamaystiran.
1.Go'aaminta socodka socodka
Isku darka sifooyinka muunada balka si loo go'aamiyo habka ka faa'iidaysiga: macdanta ceeriin ayaa lagu miiray iyada oo loo marayo 30 meshes-+30 mesh-miro-miro-shiidid ilaa -30 mesh.
——-30 mesh muunad isku qasan oo kala soocida birta ee durbaanka magnetic + saxan siman + giraan toosan + giraan toosan oo bir bir ah oo xoog leh - diirada waxaa loo kala saaray + 300 mesh dhexdhexaad-hadhuudh feldspar alaabada iyo -300 mesh dhoobo fiican——Dabeecadda wanaagsan ayaa markaa loo isticmaalaa in lagu soo saaro birta laba jeer iyada oo loo marayo slurry elektromagnetic si loo helo badeeco heer sare ah oo budada ah.
2.Tijaabada kala soocida birta ceeriin
Macdanta ceyriinka ah waxaa lagu miiray 30 meshes, natiijadii falanqaynta waxaa lagu muujiyay shaxda 1.

Shaxda 2. Natiijooyinka tijaabada kala soocida magnetic caadiga ah
Macdanta ceyriinka ah ayaa la baaraa + shiididda macdanta + saddex-jeer ka saarista birta habka tijaabada caadiga ah, iyo wax soo saarka dhexe iyo hoose-hoose waxaa lagu heli karaa wax-soo-saarka 92.57%, a Fe2O3 content 0.525% iyo caddaan ah 36.15%. Waa in la tixgeliyo in lagu nadiifiyo oksaydhka birta ee dhogorta leh iyo silicate birta ee dhoobada wanaagsan leh dhexdhexaad dhexdhexaad ah oo heer sare ah mashiinka slurry electromagnetic ka dib marka la kala saaro.
3.Birta oo laga soo saaro dhoobada qadhaadh
Qaybta labaad ee Lihuan waxaa laga soo saaraa qulqulka wanaagsan ee ka hooseeya -300 mesh iyada oo loo marayo qulqulka, iyo habka looga saarayo birta laba jeer mashiinka slurry electromagnetic waxaa loo isticmaalaa si loo helo badeecada diirran ee budada ah.Socodka geedi socodka waxa lagu muujiyay sawirka 2, natiijadiina waxa lagu muujiyay shaxda 3.
