Udaka olusahwa luyingxube yempuphu yamatshe namanzi akhiqizwa ngesikhathi sokusika nokupholisha imabula negranite. Izindawo eziningi enyakatho yezwe lethu ziyizisekelo ezibalulekile zokucubungula amatshe, futhi inani elikhulu lodaka olusahwa likhiqizwa minyaka yonke, futhi ukufakwa kwalo kudinga indawo enkulu yemithombo yomhlaba. Udaka lwamatshe lunokwakheka okuhle futhi kunzima ukululahla. Kulula ukundiza esibhakabhakeni emoyeni onamandla, futhi lugeleza emfuleni ngamanzi emvula ezinsukwini zemvula, okubangela ukungcola okukhulu kwemvelo.
Amaminerali amakhulu e-gangue odakeni lwesaha afaka phakathi i-feldspar, i-quartz, i-calcite, i-dolomite, i-amphibole, njll. Amaminerali amakhulu ensimbi kanye nokungcola kufaka phakathi i-iron silicate njenge-mechanical iron, i-magnetite, i-iron oxide, i-pyrite, kanye ne-biotite. Njengamanje, indlela ephelele yokusebenzisa udaka lwesaha iwukukhiqiza izitini ezivuvukele ngokhonkolo kanye nokwenza izinto zokusetshenziswa ze-ceramic ngemuva kokususa ukungcola. Owokuqala unamandla amakhulu okucubungula kanti owokugcina unenzuzo ephezulu kwezomnotho.
Ucwaningo lwezinzuzo
Kulesi sihloko, kwenziwa ucwaningo lokusetshenziswa okuphelele kanye nokuhlolwa kokuzuza kwezakhi zodaka olumele endaweni yaseJining. Amaminerali abalulekile odakeni lwesaha yi-feldspar, insimbi yomshini, insimbi yamagnetic, njll., kanti ukungcola okuyingozi yi-limonite, i-biotite, i-muscovite, i-calcite, i-dolomite, i-hornblende, njll. Usayizi wezinto ezibonakalayo awulingani, izinhlayiya eziqinile zisukela ku-1-4mm kanye nodaka oluncane oluthile -0.037mm. Phakathi kwazo, insimbi yomshini ekhiqizwa ngesikhathi sokucubungula kanye nensimbi yamagnetic ku-ore eluhlaza ingahlukaniswa ngogesi ibe yimikhiqizo yokugxila kwensimbi. Ngemva kokuhlukaniswa okunamandla kukagesi, ukungcola okuqukethe insimbi njenge-limonite, i-biotite, kanye ne-amphibole kungasuswa. Imikhiqizo yokugxila ngamatshe, ingxenye ngayinye yemisila yamagnetic ingasetshenziswa njengezitini ezinomoya noma izinto zesamente, ukuze kufezwe injongo yokusetshenziswa okuphelele.
1.Ukunqunywa kokugeleza kwenqubo
Ukuhlanganisa izakhiwo zesampula yothuli lwesawdust ukuze kutholakale inqubo yokuzuza: i-ore eluhlaza ihlungwa ngokusebenzisa ama-meshes angu-30-+30 ama-mesh coarse-grain grinding kuya ku--30 mesh.
——-30 mesh ingxube yesampulu yensimbi exubile ngesihlukanisi sikamazibuthe sedrama + ipuleti eliyisicaba + indandatho eqondile + indandatho eqondile ukususwa kwensimbi enamandla kazibuthe-i-concentrate ihlukaniswe ngemikhiqizo ye-+300 mesh medium-grain feldspar concentrate kanye nodaka oluncane lwe--300 mesh——I-sludge encane ibe isisetshenziswa ukususa insimbi kabili nge-slurry kagesi ukuze kutholakale umkhiqizo wokugxila wezinga lempuphu encane.
2.Ukuhlolwa kokuhlukaniswa kwamandla kazibuthe e-ore eluhlaza
I-ore eluhlaza yahlungwa ngama-meshe angu-30, futhi imiphumela yokuhlaziya iboniswe kuThebula 1.
Ithebula 1. Umphumela Wokuhlolwa Kokuzuza Nokuhlola
Gaya i-ore enamabala aqinile enesivuno esingu-17.35% kuya ku-30 mesh, hlanganisa nomkhiqizo ngaphansi kwesihlungo, bese udlula enkambisweni evamile yokuhlukanisa amandla kagesi ye-drum magnetic separator + flat plate + vertical ring + vertical ring. Ukugeleza kwenqubo kuboniswe kuMfanekiso 1, kanti imiphumela yokuhlolwa iboniswe kuThebula 2.
Umfanekiso 1. Ukugeleza kwenqubo yokuhlolwa kokuhlukaniswa kwamagnetic okuvamile kwe-ore eluhlaza.
Ithebula 2. Imiphumela yokuhlolwa kokuhlukaniswa kwamagnetic okuvamile
I-ore eluhlaza ihlolwe + ukugaya i-ore + inqubo yokuhlola evamile yokususa insimbi kathathu, kanti imikhiqizo yokugxila ephakathi nephansi ingatholakala ngesivuno esingu-92.57%, okuqukethwe kwe-Fe2O3 okungu-0.525% kanye nobumhlophe obungu-36.15%. Kufanele kucatshangelwe ukuhlanza i-iron oxide ecolekile kanye ne-iron silicate odakeni oluhle ngomshini omuhle we-slurry kagesi ophakathi nendawo, ngemuva kokuhlukaniswa.
3. Ukususwa kwensimbi odakeni olucolekile
I-concentrate yesibili ye-Lihuan ikhishwa odakeni oluncane olungaphansi kwe-mesh engu-300 ngokuchichima, futhi inqubo yokususa insimbi kabili ngomshini we-slurry kagesi isetshenziselwa ukuthola umkhiqizo we-concentrate we-fine powder. Ukugeleza kwenqubo kuboniswe kuMfanekiso 2, kanti imiphumela yokuhlolwa iboniswe kuThebula 3.
Isithombe 2. Ukugeleza kwenqubo yokuhlolwa kokususwa kwensimbi yodaka olucolekile
Ithebula 3. Inkomba yokususwa kwensimbi yodaka olucolekile
Ngemva kokulinganisa i-Lihuan concentrate, ubumhlophe be-+300 mesh medium-grain feldspar concentrate bukhuphuke busuka ku-36.15% kuya ku-56.49%, kanti ubumhlophe bodaka oluhle bunciphe bufika ku-23.07%. I-sludge encane ye--300 mesh isuswa ensimbini kabili nge-slurry kagesi, bese kutholakala umkhiqizo we-ceramic-grade fine powder onesivuno esingu-42.31% kanye nobumhlophe obungu-41.80%.
3. Ukuhlolwa kwenqubo ephelele
Izimo zokuhlola eziphelele kanye nezinkomba zokwenza yonke inqubo yokuhlola.
Isithombe 3. Inqubo yonke yokuhlola udaka lokusika
Ithebula 4. Izinkomba zokuhlola zenqubo yonke
Okunamathiselwe: Izinga lokushisa lamabhisikidi 1200℃
I-ore yodaka olusakiwe ihlungiwe + umhlabathi + ukuhlukaniswa okubuthakathaka kwamandla kazibuthe + ipuleti eliyisicaba + indandatho eqondile + indandatho eqondile + inqubo yokuhlukanisa amandla kazibuthe ye-slurry kagesi ukuze kutholakale i-ore yensimbi enesivuno esingu-0.32% kanye nebanga le-TFe elingu-62.35%. Ngesivuno esingu-38.56% kanye nobumhlophe obungu-54.69% bemikhiqizo ye-feldspar ye-ceramic grade ephakathi nendawo kanye nesivuno esingu-42.31% sobumhlophe bemikhiqizo ye-ceramic grade yempuphu ecolekileyo engu-41.80%; isivuno esiphelele se-magnetic tailings singu-18.81%, Singasetshenziswa njengezinto zokusetshenziswa zezitini ezivuthisiwe.
Le nqubo yezobuchwepheshe ivumela ukusetshenziswa okuphelele kwe-saw mud tailings, futhi ingathola izinzuzo eziphezulu kwezomnotho kanye nokubaluleka kokuvikelwa kwemvelo emphakathini.
