São Paulo, Lub Ob Hlis 2nd (Argus) - Tom qab ze li plaub lub hlis - kaw, Sigma Lithium, Brazil tus tsim khoom loj tshaj plaws spodumene, tau rov ua haujlwm ntawm nws cov khoom lag luam.
Kev tsim khoom ntawm Sigma's mine hauv Grota do Cirilo, Brazil, rov pib dua thaum Lub Ib Hlis 31st. Lub tuam txhab tau hais tias qhov rov pib dua yog "nyob rau lub sijhawm". Txawm li cas los xij, CEO Ana Cabral tau hais rau lub Kaum Ib Hlis 2025 tias lub mine yuav rov pib ua haujlwm hauv "ob mus rau peb lub lis piam", txhais tau tias nws yuav tsum tau rov pib dua thaum Lub Kaum Ob Hlis 5th.
Sigma tau nres tag nrho cov haujlwm ntawm Grota do Cirilo thaum Lub Kaum Hli Ntuj xyoo tas los txhawm rau txhim kho cov khoom siv mining thiab hloov cov khoom siv raw khoom.
Tus neeg ua haujlwm miner kuj tau hais tias qee qhov kev tsim kho cov nyiaj tau los ntawm kev muag nws cov khoom siv lithium qhuav (piv txwv li, tailings, tseem hu ua nplua). Nws tau hais tias muag 950,000 tons ntawm tailings ntawm $ 140 ib tuj yuav ua kom cov nyiaj tau los sib npaug ntawm kev muag 70,000 tons ntawm spodumene ntawm $ 1,800 ib tuj. 70,000 tons yog kwv yees li ntawm kuv qhov peb -hli puv peev xwm.
Cov ntsiab lus lithium ntawm tailings yog li 1%.
Lub tuam txhab yuav tshaj tawm cov kev qhia tshiab tag nrho - xyoo ntau lawm thaum nws mus txog lub xeev "ruaj khov" ntau lawm (xav kom txog thaum lub Peb Hlis kawg), thiab tag nrho cov khoom siv mining yuav rov qab los rau lub sijhawm no.
Vim muaj teeb meem kev nyab xeeb, ob ntawm Sigma cov khib nyiab pov tseg yav dhau los tau raug tso tseg los ntawm Brazilian Labor Ministry, thiab National Mining Agency (ANM) kuj tau tshawb xyuas lub tuam txhab rau tib lub laj thawj. ANM tseem tsis tau tshaj tawm tsab ntawv tshaj tawm kev tshuaj xyuas, thiab Sigma tsis lees paub qhov ua txhaum cai.
Kev kaw cov khib nyiab pov tseg tsis cuam tshuam rau kuv txoj haujlwm, tab sis yog tias ANM pom qhov tsis sib xws hauv daim ntawv tshaj tawm, Sigma yuav tau tawm tsam nws hauv tsev hais plaub lossis lees txais tag nrho cov lus pom zoo los ntawm lub koom haum.
