UVale umemezele ngoMashi 16 ukuthi inkampani iqale ukusebenza kwendawo yokuhlunga ye-taaltration e-DA Varjen ehlanganisiwe yokusebenza. Lesi yisitshalo sokuqala se-fieltration fieltration esihlelelwe ukuvula i-vale e-minas gerais. Ngokusho kohlelo, uVale uzotshala imali ephelele yama-US $ 2.3 billion ekwakheni isitshalo se-tailings fieltration phakathi kuka-2020 no-2024.
Kuyaqondakala ukuthi ukusetshenziswa kwezitshalo ze-tailings fieltration akunakunciphisa ukuncika edamu kuphela, kodwa futhi kuthuthukisa ibanga elijwayelekile lephothifoliyo yomkhiqizo weVale ngokusebenzisa imisebenzi enizuzisayo. Ngemuva kokuhlungwa kwe-Iron Ore, okuqukethwe kwamanzi kungancishiswa ubuncane, futhi iningi lezinto ezibonakalayo ku-tailings lizogcinwa ngefomu eliqinile, ngaleyo ndlela linciphise ukuncika edamu. UVale washo ukuthi inkampani ihlela ukuvula isitshalo sokuqala se-filtration endaweni ehlanganisiwe yokusebenza e-2021, kanye nesitshalo sesibili se-filtration endaweni yokusebenza kwe-Itabira ehlanganisiwe endaweni engama-2022. Izitshalo ezine zokuhlunga Sizohlinzeka ngezinsizakalo zenqwaba yabasebenzi be-iron ore ore anekhono lokukhiqiza eliphelele lamathani / ngonyaka wezigidi ezingama-64.
UVale umemezele ku "2020 Production Report" ukhishwe ngoFebhuwari 3, 2021 ukuthi kwikota yesithathu ka-2021, njengoba iMayini Nombolo 3 Yamayini ifakiwe, inkampani izobuyisela futhi amathani okukhiqiza. Kusesigabeni sokugcina sokwakhiwa. Imisipha ethambekele kwiMmangaliso Nombolo 3 Dam izoba ne-30% yazo zonke izindlela ezikhiqizwe ngesikhathi sokusebenza. Ukuvulwa kwesitshalo se-fieltration se-tailings e-Davarren Compreyint Operation Area kungenye inqubekela phambili ye-Vale ye-Vale eyenziwe ekukhuzeni kwe-Iron Ore Production kanye nokubuyisela umthamo wayo wonyaka wokukhiqiza amathani angama-2022 ngasekupheleni kuka-2022.
