Njengenye yezona zimbiwa zakuqala nezisetyenziswa kakhulu emhlabeni, intsimbi ekrwada yeyona nto ibalulekileyo kwimveliso yentsimbi kunye nentsimbi.Okwangoku, izibonelelo zentsimbi ziyancipha, ezibonakaliswe ngomlinganiselo ophezulu we-ore ore xa kuthelekiswa nobutyebi obuninzi, i-ore ehambelana ngakumbi, kunye nokuqulunqwa kwe-ore eyinkimbinkimbi.Intsimbi iqhele ukutsalwa kwintsimbi yayo, eyaziwa ngokuba yihematite okanye imagneti, ngenkqubo ebizwa ngokuba yi-iron ore beneficiation.Amanyathelo athile abandakanyekayo ekutsalweni kwesinyithi kunokwahluka ngokuxhomekeke kubume bentsimbi ekrwada kunye neemveliso ezifunwayo, kodwa inkqubo ngokubanzi ibandakanya ezi zigaba zilandelayo:
Ukwembiwa kwemigodi
Iidiphozithi zentsimbi zichongwa kuqala ngemisebenzi yokuhlola.Nje ukuba kufunyanwe idiphozithi esebenzayo, intsimbi ekrwada itsalwa emhlabeni kusetyenziswa ubuchule bokomba obufana nomngxuma ovulekileyo okanye umgodi ongaphantsi komhlaba.Esi sigaba sokuqala sibalulekile njengoko sibeka inqanaba leenkqubo zokutsalwa ezilandelayo.
Ukutyumza kunye nokuSila
Intsimbi ekrwada ekhutshiweyo ke iye icunyuzwe ibe ngamaqhekeza amancinci ukuququzelela ukuqhubela phambili.Ukutyumza ngokuqhelekileyo kwenziwa ngokusebenzisa izityumsi zemihlathi okanye izityuzi zekhowuni, kunye nokusila kuqhutyelwa ngokusebenzisa i-autogenous grinding mills okanye iibhola zebhola.Le nkqubo inciphisa i-ore ibe ngumgubo ococekileyo, okwenza kube lula ukuphatha kunye nokusebenza kwizigaba ezilandelayo.
Ukwahlula kweMagnetic
Intsimbi ekrwada isoloko iqulethe ukungcola okanye ezinye iiminerali ekufuneka zisuswe ngaphambi kokuba zisetyenziswe ekuveliseni intsimbi nentsimbi.Ukwahlula ngemagnethi yindlela eqhelekileyo esetyenziswayo ukwahlula iiminerali zemagneti kwezi zingezizo ezemagneti.Iimagnethi ezinamandla, ezifana ne-Huate magnet separator, zisetyenziselwa ukutsala kunye nokwahlula amasuntswana entsimbi kwi-ganggue (izinto ezingafunwayo).Eli nyathelo libalulekile ekuphuculeni ukucoceka kwentsimbi ekrwada.
Uncedo
Isinyathelo esilandelayo yi-beneficiation ye-ore, apho injongo kukwandisa umxholo wentsimbi ngokusebenzisa iindlela ezahlukeneyo.Le nkqubo inokubandakanya ukuhlamba, ukuhlolwa, kunye neendlela zokwahlula umxhuzulane ukususa ukungcola kunye nokuphucula umgangatho wentsimbi.Uncedo lunokubandakanya ukuphaphatheka, apho imichiza yongezwa kwintsimbi ekrwada ukwenza amasuntswana entsimbi adadayo aze ahlukane nenye imathiriyeli.
Pelletizing okanye Sintering
Nje ukuba intsimbi ekrwada ibe luncedo, kusenokuba yimfuneko ukudityaniswa kwamasuntswana acolekileyo abe makhudlwana ukuze kucutshungulwe ngokufanelekileyo.I-Pelletizing ibandakanya ukwenza iipellets ezincinci ezingqukuva ngokuwisa intsimbi kunye nezongezo ezifana ne-limestone, i-bentonite, okanye i-dolomite.I-Sintering, kwelinye icala, ibandakanya ukufudumeza izohlwayo ze-ore kunye nokuqukuqela kunye nempepho yecoke ukwenza ubunzima obudityanisiweyo obaziwa ngokuba yi-sinter.Ezi nkqubo zilungiselela i-ore inyathelo lokugqibela lokutsalwa ngokuphucula iimpawu zayo ezibonakalayo kunye neempawu zokuphatha.
Ukunyibilika
Isinyathelo sokugqibela kwinkqubo yokukhutshwa kukunyibilika, apho intsimbi yentsimbi ifudunyezwa kwiziko eliqhumayo kunye necoke (i-carbonaceous fuel) kunye ne-limestone (esebenza njenge-flux).Ubushushu obugqithisileyo buqhekeza intsimbi ekrwada ibe yintsimbi enyibilikisiweyo, eqokelela emazantsi eziko, kunye ne-slag, edada ngaphezulu ize isuswe.Intsimbi etyhidiweyo iphonswa kwiimilo ezahlukahlukeneyo, njengeengots okanye iibhilithi, kwaye iqhubekiswa ngakumbi ukuze ifumane intsimbi efunwayo kunye neemveliso zentsimbi.
Kubalulekile ukuqaphela ukuba iidiphozithi zentsimbi ezahlukeneyo kunye nezityalo zokusetyenzwa zinokuba neenguqu kwiinkqubo ezithile ezisetyenzisiweyo, kodwa imigaqo iyonke ihlala ifana.Ukukhutshwa kwentsimbi kwi-ore yinkqubo eyinkimbinkimbi kunye neyinkqubo eninzi efuna ukulawulwa ngokucokisekileyo kwezibonelelo kunye nobuchwepheshe.Ukufakwa kwezixhobo eziphambili ezifana ne-Huate magnet separator kwandisa ukusebenza kakuhle kunye nomgangatho wenkqubo yokuhlukana, ukuqinisekisa ukuba imveliso yokugqibela ihlangabezana nemigangatho efunekayo yokuvelisa isinyithi kunye nentsimbi.
