Udaka olusarhayo luxubene nomgubo welitye kunye namanzi aphuma ngexesha lokusikwa nokupolisha imabula kunye negranite. Iindawo ezininzi emantla elizwe lethu ziziseko ezibalulekileyo zokucubungula amatye, kwaye inani elikhulu lodaka olusarhayo lwenziwa minyaka le, kwaye ukuqokelelwa kwalo kuthatha indawo enkulu yezixhobo zomhlaba. Umgubo welitye unobume obuhle kwaye kunzima ukuwulahla. Kulula ukubhabha esibhakabhakeni xa kukho umoya onamandla, kwaye ungena emlanjeni ngamanzi emvula ngeentsuku zemvula, nto leyo ebangela ungcoliseko olukhulu lokusingqongileyo.
Iiminerali eziphambili ze-gangue kwidaka lesarha ziquka i-feldspar, i-quartz, i-calcite, i-dolomite, i-amphibole, njl. Iiminerali eziphambili zesinyithi kunye nokungcola ziquka i-iron silicate efana ne-mechanical iron, i-magnetite, i-iron oxide, i-pyrite, kunye ne-biotite. Okwangoku, indlela ebanzi yokusebenzisa idaka lesarha ikakhulu kukuvelisa izitena ezivuthulukileyo zekhonkrithi kunye nokwenza izinto eziluhlaza ze-ceramic emva kokususa ukungcola. Eyokuqala inomthamo omkhulu wokucubungula kwaye eyesibini ineenzuzo eziphezulu kwezoqoqosho.
Uphando lwezibonelelo
Kule nqaku, uphando olupheleleyo lokusetyenziswa kunye novavanyo lokuzuza luyenziwa kwidaka elimeleyo lesarha kwindawo yaseJining. Iiminerali ezixabisekileyo kwidaka lesarha yifeldspar, isinyithi soomatshini, isinyithi semagnethi, njl.njl., kwaye ukungcola okuyingozi yilimonite, biotite, muscovite, calcite, dolomite, hornblende, njl.njl. Ubungakanani bezinto abulingani, amasuntswana arhabaxa aqala kwi-1-4mm kunye nodaka oluncinci oluyi--0.037mm. Phakathi kwazo, isinyithi soomatshini esiveliswa ngexesha lokucubungula kunye nesinyithi semagnethi kwi-ore eluhlaza zinokwahlulwa ngemagnethi zibe ziimveliso zesinyithi esiqinileyo. Emva kokwahlulwa ngamandla kwemagnethi, ukungcola okuqulethe isinyithi okufana nelimonite, biotite, kunye ne-amphibole kunokususwa. Iimveliso zesinyithi esiqinileyo, icandelo ngalinye leentsalela zemagnethi lingasetyenziswa njengezitena ezivuthelweyo okanye izinto zesamente, ukuze kufezekiswe injongo yokusetyenziswa ngokupheleleyo.
1.Ukumiselwa kokuhamba kwenkqubo
Ukudibanisa iipropati zesampulu yothuli lwesarha ukuze kuchongwe inkqubo yokuphucula: i-ore eluhlaza ihluzwa nge-meshes ezingama-30-+30 mesh coarse-grain grinding ukuya kwi--30 mesh.
——-30 mesh mixed iron mixed sampuli by drum magnetic separator + flat plate + vertical ring + vertical ring strong magnetic iron removal-iconcentrate yahlulwe yaba yi +300 mesh medium-grain feldspar concentrate products kunye ne -300 mesh fine mud——Emva koko olu daka lucolekileyo lusetyenziswa ukususa isinyithi kabini nge-electromagnetic slurry ukuze kufunyanwe imveliso ecolekileyo yomgubo ocolekileyo.
2.Uvavanyo lokwahlulwa kwemagnethi ye-ore eluhlaza
I-ore eluhlaza yahluzwa ngee-meshes ezingama-30, kwaye iziphumo zohlalutyo ziboniswe kwiTheyibhile 1.
Itheyibhile 1. Iziphumo zoVavanyo lokuNceda nokuHlola
Gaya i-ore erhabaxa enesivuno se-17.35% ukuya kwi-30 mesh, udibanise nemveliso phantsi kwesihluzo, uze udlule kwinkqubo eqhelekileyo yokwahlula i-magnetic ye-drum magnetic separator + flat plate + vertical ring + vertical ring. Ukuhamba kwenkqubo kuboniswe kuMfanekiso 1, kwaye iziphumo zovavanyo ziboniswe kwiTheyibhile 2.
Umfanekiso 1. Ukuhamba kwenkqubo yovavanyo oluqhelekileyo lokwahlulwa kwemagnethi ye-ore eluhlaza.
Itheyibhile 2. Iziphumo zovavanyo oluqhelekileyo lokwahlulwa kwemagnethi
I-ore eluhlaza ihluzwa + i-ore grinding + inkqubo yovavanyo oluqhelekileyo lokususa isinyithi kathathu, kwaye iimveliso ezixutyiweyo eziphakathi nezisezantsi zinokufunyanwa ngesivuno se-92.57%, umxholo we-Fe2O3 we-0.525% kunye nobumhlophe be-36.15%. Kufuneka kuthathelwe ingqalelo ukucoca i-iron oxide ecolekileyo kunye ne-iron silicate eludakeni olucolekileyo ngomatshini we-slurry we-electromagnetic ophakathi, ophezulu emva kokuhlelwa.
3. Ukususwa kwentsimbi kwidaka elincinci
I-concentrate yesibini yeLihuan ikhutshwa kwi-fine sludge engaphantsi kwe-300 mesh ngokugqithisela, kwaye inkqubo yokususa isinyithi kabini ngomatshini we-electromagnetic slurry isetyenziselwa ukufumana imveliso ye-fine powder concentrate. Ukuhamba kwenkqubo kuboniswe kuMfanekiso 2, kwaye iziphumo zovavanyo ziboniswe kwiTheyibhile 3.
