Kutshanje, intatheli evela eChina i-Metallurgical News ifunde kuVale ukuba emva kweminyaka eyi-7 yophando kunye notyalo-mali malunga ne-50 yezigidi zeereais (malunga ne-US $ 878,900), inkampani iphuhlise ngempumelelo inkqubo yokuvelisa i-ore ephezulu ehambelana nophuhliso oluzinzileyo.I-Vale isebenzise le nkqubo yemveliso kwindawo yokusebenza yentsimbi yenkampani eMinas Gerais, eBrazil, kwaye iguqulela ukucutshungulwa kweentsalela ezifuna ukusetyenziswa kwamadama okanye iindlela zokupakisha kwiimveliso ezikumgangatho ophezulu.Iimveliso ezikrwada eziveliswe yile nkqubo zingasetyenziswa kushishino lokwakha.
Kuyaqondwa ukuba ukuza kuthi ga ngoku, iVale icubungule kwaye yavelisa malunga neetoni ezingama-250,000 zemveliso yesanti yeminerali ekumgangatho ophezulu, enomxholo ophezulu we-silicon, umxholo wesinyithi ophantsi kakhulu, kunye nokufana kweekhemikhali eziphezulu kunye nobukhulu bamasuntswana afanayo.UVale uceba ukuthengisa okanye ukunikela ngemveliso ukuvelisa ikhonkrithi, udaka, isamente okanye ukugalela iindlela.
UMarcello Spinelli, uSekela Mongameli oLawulayo weVale's Iron Ore Business, uthe: “Kukho imfuneko enkulu yesanti kushishino lokwakha.Iimveliso zethu ze-ore zinika ukhetho oluthembekileyo kwishishini lokwakha, ngelixa linciphisa impembelelo yokusingqongileyo yonyango lwe-tailings.Impembelelo embi ebangelwe.”
Ngokweenkcukacha-manani zeZizwe eziManyeneyo, imfuno yonyaka yehlabathi yesanti iphakathi kweetoni ezingama-40 eebhiliyoni kunye neetoni ezingama-50 eebhiliyoni.Isanti iye yaba bubutyebi bendalo obunesona sixa sikhulu sokutsalwa kokwenziwa ngumntu emva kwamanzi.Le mveliso yesanti yeeminerali yeVale ivela kwimveliso yentsimbi.Intsimbi ekrwada inokuba yintsimbi emva kweenkqubo ezininzi ezinjengokutyumza, ukucocwa, ukucola kunye nokuzuza uncedo kumzi-mveliso.Kwinkqubo yesiNtu yokufumana uncedo, iimveliso ezivela ngaphandle ziya kuba ziintsalela zezimbiwa, ekufuneka zilahlwe ngamadama okanye kwimfumba.Inkampani iphinda ihlaziye iimveliso zentsimbi ekrwada kwinqanaba lokuxhamla ide ihlangabezane neemfuno zomgangatho kwaye ibe yimveliso yesanti yezimbiwa ekumgangatho ophezulu.UVale uthe ngokusebenzisa inkqubo yokuguqula ii-tailings zibe yi-ore ekumgangatho ophezulu, yonke itoni yeemveliso eziveliswayo inokunciphisa i-1 toni ye-tailings.Kuxelwe ukuba abaphandi abavela kwiZiko leeMinerali eziZinzileyo kwiYunivesithi yaseQueensland e-Australia kunye neYunivesithi yaseGeneva eSwitzerland ngoku baqhuba uphando oluzimeleyo ukuhlalutya iimpawu zeemveliso zesanti yezimbiwa zeVale ukuze baqonde ukuba ngaba ngokwenene banokuba yinto ezinzileyo. kwisanti.Kwaye ukunciphisa kakhulu ubungakanani benkunkuma eyenziwa yimisebenzi yemigodi.
UJefferson Corraide, uMphathi oLawulayo weVale's Brucutu kunye neAgualimpa indawo yokusebenza edibeneyo, uthe: “Olu hlobo lweemveliso zentsimbi ziimveliso eziluhlaza ngokwenene.Zonke iimveliso ze-ore zicutshungulwa ngeendlela zomzimba.Ukwakhiwa kweekhemikhali zemathiriyeli ekrwada akutshintshwanga ngexesha lokusetyenzwa, kwaye imveliso ayinayo ityhefu kwaye ayinabungozi. ”
UVale uthe uceba ukuthengisa okanye ukunikela ngaphezu kwe-1 yezigidi zeetoni zemveliso ye-ore ngo-2022, kunye nokwandisa imveliso ye-ore kwi-2 yezigidi zeetoni ngo-2023. Kubikwa ukuba abathengi bale mveliso kulindeleke ukuba bavele kwimimandla emine. eBrazil, eMinas Gerais, e-Espirito Santo, eSao Paulo naseBrasilia.
"Sikulungele ukwandisa ngakumbi imarike yesicelo seemveliso zesanti yezimbiwa ukusuka ngo-2023, kwaye ngenxa yoku siseke iqela elizinikeleyo ukuba liqhube eli shishini litsha."utshilo uRogério Nogueira, umlawuli wemarike yentsimbi yeVale.
“Okwangoku, ezinye iindawo zemigodi eMinas Gerais nazo zilungiselela uthotho lwamalungiselelo okwamkela le nkqubo yemveliso.Ukongeza, sisebenzisana nenani lamaziko ophando ukuphuhlisa izisombululo ezitsha kwaye sizibophelele kunyango olunengqiqo lwentsimbi.Iintsimbi zentsimbi zinika iingcamango ezintsha. ”utshilo uAndré Vilhena, umphathi weshishini laseVale.Ukongeza ekusebenziseni isiseko esikhoyo kwindawo yemigodi yentsimbi, iVale ikwaseke ngokukodwa uthungelwano olukhulu lothutho ukuze luhambise ngokufanelekileyo nangokufanelekileyo iimveliso zesanti yezimbiwa ezizinzileyo ukuya kumazwe amaninzi eBrazil.“Ujoliso lwethu kukuqinisekisa ukuzinza kweshishini lentsimbi, kwaye sinethemba lokunciphisa indawo engqongileyo yokusebenza kwenkampani ngeli shishini litsha.”UVilliena wongeza.
I-Vale iqhube uphando kwizicelo zonyango lwe-tailings ukususela ngo-2014. Ngo-2020, inkampani yavula isityalo sokuqala sokulinga esisebenzisa i-tailings njengeyona nto iphambili ukuvelisa iimveliso zokwakha-imboni yezitena zePico.Isityalo sibekwe kwindawo yemigodi yePico e-Itabilito, eMinas Gerais.Okwangoku, i-Federal Technical Education Centre yaseMinas Gerais iphuhlisa intsebenziswano yobugcisa kunye nePico Brick Factory.Eli ziko lathumela abaphandi abangaphezu kwe-10, kubandakanywa oonjingalwazi, abafundi abathweswe izidanga, abangekabinazidanga kunye nabafundi bekhosi yobugcisa, kwiPico Brick Factory ukuze baqhube uphando ngokobuqu.
Ukongeza kuphando kunye nophuhliso lweemveliso zendalo, i-Vale iphinde yathatha amanyathelo ahlukeneyo okunciphisa inani lee-tailings, okwenza imisebenzi yemigodi ibe yinto ezinzileyo.Inkampani izibophelele ekuphuhliseni iteknoloji yokulungisa ezomileyo ezingadingi manzi.Okwangoku, malunga ne-70% yeemveliso ze-iron ore ze-Vale ziveliswa ngeteknoloji yokucubungula okomileyo.Inkampani yathi ukusetyenziswa kwetekhnoloji yokucoca eyomileyo kuhambelana ngokusondeleyo nomgangatho wentsimbi.I-iron ore kwindawo yemigodi yaseCarajás inomxholo ophezulu wensimbi (ngaphezu kwe-65%), kwaye ukucubungula kufuneka kuphela ukutyunyuzwa kunye ne-sieved ngokwe-particle size.
I-subsidiary ye-Vale iphuhlise itekhnoloji eyomileyo yokwahlula i-magnetic ore ecolekileyo, esetyenziswe kwiplanti yokulinga eMinas Gerais.I-Vale isebenzisa le teknoloji kwinkqubo yokuzuza kwi-ore yentsimbi ephantsi.Iplanti yokuqala yokuthengisa iya kusetyenziswa kwindawo yokusebenza yaseDavarren ngo-2023. UVale uthe isityalo siya kuba nomthamo wemveliso yonyaka we-1.5 yezigidi zeetoni, kwaye utyalo-mali lulonke kulindeleke ukuba lube yi-US $ 150 yezigidi.Ukongeza, i-Vale ivule iplanti yokucoca i-tailings kwindawo ye-Great Varjin yemigodi, kwaye iceba ukuvula iindawo ezintathu zokuhluza ii-tailings kwikota yokuqala ye-2022, enye ifumaneka kwindawo yemigodi yaseBrucutu kwaye ezimbini zifumaneka e-Iraq.Indawo yemigodi yaseTagbila.
