I-Saw udaka ngumxube womgubo wamatye kunye namanzi avelisiweyo ngexesha lokusikwa kunye nokupholiswa kwemarble kunye negranite.Iindawo ezininzi ezisenyakatho yelizwe lethu zisisiseko esibalulekileyo sokulungiswa kwamatye, kwaye inani elikhulu lodaka lwesarha luveliswa minyaka yonke, kwaye ukupakishwa kwayo kuthatha. phezulu indawo enkulu yobutyebi bomhlaba.I-powder yamatye inokwakheka okulungileyo kwaye kunzima ukuyilahla.Kulula ukubhabha esibhakabhakeni kumoya onamandla, kwaye uqukuqela usiya emlanjeni unamanzi emvula ngeentsuku zemvula, nto leyo ebangela ungcoliseko olukhulu lokusingqongileyo.
Iiminerali eziphambili ze-ganggue kwi-saw mud ziquka i-feldspar, i-quartz, i-calcite, i-dolomite, i-amphibole, njl. Izimbiwa eziphambili zetsimbi kunye nokungcola zibandakanya i-silicate yensimbi efana ne-iron mechanical, i-magnetite, i-iron oxide, i-pyrite, kunye ne-biotite. Okwangoku, ukusetyenziswa okubanzi indlela yodaka isarha ikakhulu ukuvelisa izitena aerated zekhonkrithi kunye nokwenza izixhobo zeceramic ekrwada emva kokususa ukungcola.Eyangaphambili inomthamo omkhulu wokucubungula kwaye le yokugqibela ineenzuzo eziphezulu zoqoqosho.
Uphando lwenzuzo
Kweli nqaku, uphando olubanzi lokusetyenziswa kunye novavanyo lwe-beneficiation lwenziwa kummeli wabona udaka kwindawo ye-Jining.Izimbiwa ezixabisekileyo kwi-saw mud yi-feldspar, isinyithi somatshini, intsimbi yamagnetic, njl., kunye nokungcola okuyingozi yi-limonite, i-biotite, i-muscovite, i-calcite, i-dolomite, i-hornblende, njl njl. Ubungakanani bezinto eziphathekayo azilingani, iinqununu ezinqabileyo zivela kwi-1-4mm kunye nezinye -0.037mm zodaka oluhle. Phakathi kwazo, isinyithi somatshini esiveliswa ngexesha lokucubungula kunye nentsimbi yamagnetic kwindawo eluhlaza. Intsimbi ekrwada inokohlulwa ngokwemagnethi ibe yimveliso yentsimbi.Emva kokwahlukana okunamandla kwamagnetic, ukungcola okunentsimbi okufana ne-limonite, i-biotite, kunye ne-amphibole inokususwa.Iimveliso zokugxilwa kwamatye, icandelo ngalinye le-magnetic tailings linokusetyenziswa njengezitena ezine-aerated okanye izinto zesamente, ukuze kuphunyezwe injongo yokusetyenziswa ngokubanzi.
1.Ukumiselwa kwenkqubo yokuhamba
Ukudibanisa iipropathi zesawdust yesampuli ukumisela inkqubo yokuzuza: intsimbi ekrwada ekrwada ihluzwa ngeeminatha ezingama-30-+30 umnatha orhabaxa-oziinkozo ukucola ukuya kwi -30 mesh.
—--30 umnatha oxubeneyo wesampulu yentsimbi yokwahlulwa ngegubu lokwahlulahlula kazibuthe + ipleyiti ecaba + umsesane othe nkqo + umsesane othe nkqo oqinileyo wokususwa kwentsimbi enozibuthe-ugxininiso luhlelwa ngokwe +300 umnatha ophakathi kweenkozo eziziinkozo zefeldspar kunye ne-300 mesh yodaka oluhle.—-Udaka olucolekileyo ke lusetyenziselwa ukususa intsimbi kabini ngodaka lwe-electromagnetic ukufumana imveliso yoxinaniso yodidi lomgubo ocolekileyo.
2.Uvavanyo lokwahlulwa kwentsimbi ekrwada
I-ore ekrwada yahluzwa nge-30 meshes, kwaye iziphumo zokuhlalutya ziboniswe kwiThebhile 1.
Itheyibhile 1. Iziphumo zeNzuzo kunye noVavanyo lokuHlola
Gaya i-ore ecoarse-grained kunye nesivuno se-17.35% ukuya kwi-30 mesh, xuba kunye nemveliso phantsi kwe-sieve, kwaye uhambe kwinkqubo yokwahlulwa kwemagnethi yesiqhelo ye-drum magnetic separator + ipleyiti ecaba + umsesane othe nkqo + umsesane othe nkqo.Ukuhamba kwenkqubo kuboniswe kuMfanekiso 1, kwaye iziphumo zovavanyo ziboniswa kwiThebhile 2.
Umzobo 1. Ukuhamba kwenkqubo yovavanyo oluqhelekileyo lolwahlulo lwemagnethi lwentsimbi ekrwada ekrwada.
Itheyibhile 2. Iziphumo zovavanyo oluqhelekileyo lokuhlukana kwamagnetic
I-ore ekrwada ihlolwe + i-ore yokusila + inkqubo yovavanyo oluqhelekileyo lokususa isinyithi kathathu, kwaye imveliso ye-concentrate ephakathi kunye nesezantsi ingafumaneka ngesivuno se-92.57%, umxholo we-Fe2O3 we-0.525% kunye nomhlophe we-36.15%. Kufuneka kuthathelwe ingqalelo ukuhlambulula i-oxide yentsimbi ecolekileyo kunye nentsimbi ye-silicate eludakeni oluhle kunye nomatshini ophakathi, ophezulu we-electromagnetic slurry machine emva kokuhlelwa.
3.Ukususwa kweayini eludaka olucolekileyo
I-concentrate yesibini ye-Lihuan ikhutshwe kwi-sludge emihle engaphantsi kwe-300 mesh ngokuphuphuma, kunye nenkqubo yokususa isinyithi kabini ngomatshini we-electromagnetic slurry isetyenziselwa ukufumana imveliso ye-powder concentrate.Ukuhamba kwenkqubo kuboniswe kuMfanekiso 2, kwaye iziphumo zovavanyo ziboniswe kwiThebhile 3.
Umfanekiso 2. Inkqubo yokuhamba kovavanyo lokususa intsimbi yodaka olucolekileyo
Itheyibhile 3. Isalathiso sokususwa kwentsimbi yodaka olucolekileyo lodaka
Emva kokuhlelwa kwe-concentrate ye-Lihuan, ubumhlophe be-+300 mesh medium-grain-grain feldspar concentrate inyuke ukusuka kwi-36.15% ukuya kwi-56.49%, kwaye ubumhlophe bodaka olucolekileyo lwehla ukuya kwi-23.07%.-I-300 i-mesh i-sludge ecocekileyo isuswe kwintsimbi kabini nge-slurry ye-electromagnetic, kunye nemveliso ye-ceramic-grade ye-powder ecocekileyo kunye nesivuno se-42.31% kunye nobumhlophe be-41.80% inokufumaneka.
3.Uvavanyo lwenkqubo yonke
Iimeko zovavanyo olubanzi kunye nezalathi zokwenza uvavanyo lwenkqubo yonke.
Umzobo 3. Yonke inkqubo yokubona inkqubo yovavanyo lodaka
Itheyibhile 4. Iimpawu zovavanyo zenkqubo yonke
I-Attachment: Ubushushu beebhiskithi 1200℃
Intsimbi ekrwada esabonwayo iyahluzwa + emhlabeni + ulwahlulo olubuthathaka lwemagnethi + ipleyiti ecaba + umsesane othe nkqo + umsesane othe nkqo + ukulinganisa inkqubo yokwahlulwa koludaka lwe-electromagnetic magnetic ukufumana intsimbi ekrwada ngesivuno se-0.32% kunye nebakala leTFe lama-62.35%.Ngesivuno 38.56% kunye mhlophe 54.69% of medium-grain ceramic grade feldspar concentrate iimveliso kunye nesivuno 42.31% ubumhlophe 41.80% ecolekileyo powder grade grade concentrate iimveliso;isivuno esipheleleyo se-magnetic tailings yi-18.81% , Ingasetyenziselwa izinto ezikrwada kwizitena ezifakwe umoya.
Le nkqubo yobuchwepheshe ivumela ukusetyenziswa okubanzi kweentsalela zodaka, kwaye inokufumana inzuzo ephezulu yezoqoqosho kunye nokubaluleka kokhuseleko lwentlalo.
