Production insimbi Waste

Enye amacandelo aphambili ezoqoqosho yokunyibilikisa isinyithi. Inika umbandela ekrwada, nezinye ezininzi amashishini. Acace kunye nesinyithi non-ayoni ezifunekayo phantse kuyo yonke indawo. Kwaye amaxabiso ezi izinto ziyanda yonke imihla. kwamaxabiso ombane, Kakade, zibe nempembelelo ebalulekileyo ixabiso iimveliso ngentsimbi. Kodwa indima ebalulekileyo kusekwe kwaye ukuveliswa kwenkunkuma edlala amaxabiso.

Yaye yokunyibilikisa isinyithi zabo ezinkulu ngokukhethekileyo. Asezikhundleni iindawo ezinkulu kwaye zingcolise umoya iikhompawundi zinetyhefu, amanzi kunye nomhlaba. Kwathi ngelo xesha iindleko zokuhlala kwabo, ukugcinwa kunye nokuthuthwa nempembelelo ebalulekileyo iindleko zokuvelisa kwamashishini metallurgical. Kodwa oku kutya ziqulethe eninzi lweziqalelo enokusetyenziswa njengoko izinto eziziisekondari ekrwada. Ke kaloku indlela umninindlu, neempanza metallurgical olunjalo ibuye ibe umthombo wengeniso.

Ezi amanxuwa kubangelwa le lokunyibilikisa ngentsimbi, intsimbi uphoswe okanye ferroalloys. Kwaye umxholo kumacandelo kwezimbiwa ezahlukeneyo, nto leyo enokubandakanya intsimbi, babe ngaphezulu nkqu kubo kunokuba kwi ores efanayo zendalo. Kwaye ngenxa yokufunda zaneleyo ngesakhiwo neempawu sludges kukho ingxaki kwakhona wabo.

Fumana ubuncinane zeBlack steelmaking. Ezi ukuveliswa kwenkunkuma zisetyenziswe ematyeni yentsimbi ezininzi kunye mveliso ajikwa zeBlack zizityebi. Ukulungiselela le njongo iimveliso ukwahlukana magnetic "owomileyo" afunyenwe emva elihlazo kokuba zeBlack. A imveliso luncedo ezifunyenwe emva kwalo unyango, orenji igazi ingqalelo metal ezinkulu lokubolekwa ngentsimbi kunye neglasi dust. Iron-bacebisa zeBlack yokuqamba kangako. Kwaye ngenxa yokuba zophuculo izityalo sinter eetoni zeBlack wavelisa ezimalunga nama-40 kg ngentsimbi. Iimveliso inkunkuma eseleyo, eziquka amabala ezincinane kuphela okanye oxide intsimbi kufakwa ikhaba.

Kodwa kukho iteknoloji ezichanekileyo ukutyebiseka le zeBlack ngentsimbi. Ngoncedo ezi ilindle ukufumana iimveliso ezintathu. Eyokuqala yimveliso yesinyithi. Bekuya kuba malunga ne-10% ye-mass zeBlack. Ngoko ke, ngaphandle ebuntsimbi intsimbi, iqulathe ubumdaka ezincinane zeglasi, silicates kunye carbonates. Yakhe briquetted zize zithunyelwe isinyibilikise yesibini. Eyesibini imveliso oxide lime-yentsimbi. Kumalunga-22% yamanqaku ewonke. Iron kule mveliso kancinci. Ubukhulu becala, le nkqubo ibandakanya kwezimbiwa ngeenjongo ezahlukeneyo. Le wustite, magnetite, maghemit, goethite, hematite, ikalika hydrated, intsimbi kunye carbonates calcium, kwakunye magnesium calcium ferrites. Le mveliso zingasetyenziswa njenge material izinga eliphezulu feed ekuvelisweni sinter yentsimbi fluxed. Kwaye ke intsalela, leyo malunga ne 68% iwela kwimveliso dust. Ingxenye esemqoka layo ngumxube kwezimbiwa: silicates, spinels, tridymite, iglasi silicate kunye neemveliso lime ukuxovwa. Ezi mveliso inkunkuma nayo ilize. imveliso Silicate isetyenziswa ikakhulu xa kusakhiwa, isamente okanye ezinye iimveliso cementitious.

Unako kwakhona ukuthatha imveliso zeBlack ferromanganese, eziquka amacandelo ezininzi ezibalulekileyo. Oku orenji igazi ferromanganese kwaye ebuntsimbi intsimbi, silicates, hydroxides, oxides lokubolekwa, yemanganizi carbonates yesinyithi, iglasi silicate, kunye nemveliso crystallization yayo. Izazinzulu baye basungula indlela apho ukuziphatha owomileyo bekukubi yoxinaniso ezi ityhefu. Ngenxa yezi mveliso inkunkuma ukwenza imveliso iimveliso ezintathu.

Eyokuqala kwezi yentsimbi manganese mxube. Of ubunzima lilonke zeBlack oko nivuke kwi-17%. Le mveliso iqulethe iindawo Imagnethi yomhlaba kunye non-kazibuthe yentsimbi, manganese, Cohen zentsimbi kunye aluminium ezahlukeneyo ezishiyanayo okuqulathwe yemanganizi kunye nentsimbi, kunye oxides zabo hydroxides. Sebenzisa Le mveliso kunokuba ekuveliseni ferromanganese.

Le mveliso sesibini intlabathi silicate. Isiqingatha ubunzima zeBlack lilonke siza kuba phezu kwakhe. Isanti Silicate ibandakanya ikakhulu zwi, cristobalite, tridymite, iglasi kunye silicates. Kuwo unako ukuvelisa silicomanganese okanye ungayisebenzisa njengendlela izinto zokwakha.

I-33% livela ngothuli ngodongwe-carbonate. Le nto ndiyibhalayo silicates ezicukucezwe zancinane, carbonates, iglasi kunye nezinye izimbiwa. Le uthuli asetyenziselwa imveliso lwesamente. Baninzi ngakumbi olu hlobo lwenkunkuma, nto leyo kuzuza abantu.
