Posachedwapa, mtolankhani wochokera ku China Metallurgical News adamva kuchokera ku Vale kuti patatha zaka 7 akufufuza ndikugwiritsa ntchito ndalama zokwana ma reais pafupifupi 50 miliyoni (pafupifupi US$878,900), kampaniyo yapanga bwino njira yopangira miyala yamtengo wapatali yomwe ingathandize pakukula kokhazikika. Vale yagwiritsa ntchito njira yopangirayi kudera lomwe kampaniyo imagwiritsa ntchito miyala yachitsulo ku Minas Gerais, Brazil, ndipo yasintha njira yopangira miyala yamtengo wapatali yomwe poyamba inkafuna kugwiritsa ntchito madamu kapena njira zoikira miyala kukhala zinthu zapamwamba kwambiri. Zinthu zopangidwa ndi miyala yamtengo wapatali zomwe zimapangidwa ndi njirayi zitha kugwiritsidwa ntchito mumakampani omanga.
Zikumveka kuti mpaka pano, Vale yakonza ndi kupanga matani pafupifupi 250,000 a zinthu zamchenga zamtengo wapatali ngati zimenezi, zomwe zili ndi silicon yambiri, chitsulo chochepa kwambiri, komanso mankhwala ofanana komanso kukula kwa tinthu tating'onoting'ono. Vale ikukonzekera kugulitsa kapena kupereka zinthuzo kuti zipange konkire, matope, simenti kapena misewu yopangira miyala.
Marcello Spinelli, Wachiwiri kwa Purezidenti wa Vale's Iron Ore Business, anati: "Pali kufunikira kwakukulu kwa mchenga m'makampani omanga. Zogulitsa zathu za miyala zimapereka chisankho chodalirika kwa makampani omanga, pomwe zimachepetsa kuwonongeka kwa chilengedwe chifukwa cha kukonza ming'alu. Zotsatira zoyipa zomwe zimachitika."
Malinga ndi ziwerengero za United Nations, kufunikira kwa mchenga padziko lonse lapansi pachaka kuli pakati pa matani 40 biliyoni ndi matani 50 biliyoni. Mchenga wakhala chuma chachilengedwe chokhala ndi kuchuluka kwakukulu kwa zinthu zopangidwa ndi anthu pambuyo pa madzi. Chopangidwa ndi mchenga wa mchere ichi cha Vale chimachokera ku chinthu chopangidwa ndi chitsulo. Mchenga wosaphika ukhoza kukhala chitsulo pambuyo pa njira zingapo monga kuphwanya, kuyeretsa, kupukuta ndi kuyeretsa mufakitale. Mu njira yachikhalidwe yopangira mchere, zinthu zotsala zimakhala mipata, zomwe ziyenera kutayidwa kudzera m'madamu kapena m'matumba. Kampaniyo imakonzanso zinthu zotsala za chitsulo mu gawo lopangira mchere mpaka zitakwaniritsa zofunikira zamtundu ndikukhala chinthu chapamwamba cha mchenga wa mchere. Vale adati pogwiritsa ntchito njira yosinthira mipata kukhala miyala yabwino kwambiri, tani iliyonse ya zinthu zopangidwa ndi chitsulo imatha kuchepetsa tani imodzi ya mipata. Zanenedwa kuti ofufuza ochokera ku Institute of Sustainable Minerals ku University of Queensland ku Australia ndi University of Geneva ku Switzerland pakadali pano akuchita kafukufuku wodziyimira pawokha kuti afufuze mawonekedwe a zinthu zopangidwa ndi mchenga wa Vale kuti amvetse ngati zingakhaledi njira yokhazikika m'malo mwa mchenga. Ndipo amachepetsa kwambiri kuchuluka kwa zinyalala zomwe zimapangidwa ndi ntchito zamigodi.
Jefferson Corraide, Woyang'anira Wamkulu wa dera logwirira ntchito la Vale ku Brucutu ndi Agualimpa, anati: "Mtundu uwu wa zinthu zopangidwa ndi miyala ndi zinthu zobiriwira. Zinthu zonse zopangidwa ndi miyala zimakonzedwa pogwiritsa ntchito njira zakuthupi. Kapangidwe ka mankhwala a zinthu zopangira sikunasinthidwe panthawi yokonza, ndipo mankhwalawa si oopsa komanso osavulaza."
Vale adati ikukonzekera kugulitsa kapena kupereka matani opitilira 1 miliyoni a zinthu zopangidwa ndi miyala yamtengo wapatali pofika chaka cha 2022, ndikuwonjezera kuchuluka kwa zinthu zopangidwa ndi miyala yamtengo wapatali kufika pa matani 2 miliyoni pofika chaka cha 2023. Akuti ogula zinthuzi akuyembekezeka kuchokera m'madera anayi ku Brazil, Minas Gerais, Espirito Santo, Sao Paulo ndi Brasilia.
"Tili okonzeka kukulitsa msika wogwiritsira ntchito zinthu za mchenga wa mchere kuyambira mu 2023, ndipo pachifukwa ichi takhazikitsa gulu lodzipereka kuti liyendetse bizinesi yatsopanoyi." anatero Rogério Nogueira, mkulu wa msika wa zitsulo zachitsulo ku Vale.
"Pakadali pano, madera ena a migodi ku Minas Gerais akukonzekeranso kukonzekera kotsatira njira yopangirayi. Kuphatikiza apo, tikugwirizana ndi mabungwe angapo ofufuza kuti tipange mayankho atsopano ndipo tadzipereka kuchiza chitsulo mwanzeru. Miyala yachitsulo imapereka malingaliro atsopano," adatero André Vilhena, manejala wa bizinesi ku Vale. Kuphatikiza pa kugwiritsa ntchito zomangamanga zomwe zilipo mdera la migodi yachitsulo, Vale yakhazikitsanso njira yayikulu yoyendera kuti inyamule bwino komanso mosavuta zinthu zokhazikika za mchenga wamchere kupita kumayiko angapo ku Brazil. "Cholinga chathu ndikuwonetsetsa kuti bizinesi yachitsulo yakhazikika, ndipo tikuyembekeza kuchepetsa kuwonongeka kwa chilengedwe kwa ntchito za kampaniyo kudzera mu bizinesi yatsopanoyi." Villiena adawonjezera.
Vale yakhala ikuchita kafukufuku pa ntchito zochizira matailosi kuyambira mu 2014. Mu 2020, kampaniyo idatsegula fakitale yoyamba yoyesera yomwe imagwiritsa ntchito matailosi ngati zopangira zazikulu zopangira zinthu zomangira - fakitale ya njerwa ya Pico. Fakitaleyi ili mdera la migodi ya Pico ku Itabilito, Minas Gerais. Pakadali pano, Federal Technical Education Center ya Minas Gerais ikupanga mgwirizano waukadaulo ndi Pico Brick Factory. Malowa adatumiza ofufuza oposa 10, kuphatikiza aphunzitsi, ophunzira omaliza maphunziro, ophunzira a digiri yoyamba ndi ophunzira a maphunziro aukadaulo, ku Pico Brick Factory kuti akachite kafukufuku payekha.
Kuwonjezera pa kafukufuku ndi chitukuko cha zinthu zachilengedwe, Vale yatenganso njira zosiyanasiyana kuti ichepetse kuchuluka kwa mipata, zomwe zimapangitsa kuti ntchito za migodi zikhale zokhazikika. Kampaniyo yadzipereka kupanga ukadaulo wokonza zinthu zouma zomwe sizifuna madzi. Pakadali pano, pafupifupi 70% ya zinthu za Vale zopangidwa ndi chitsulo zimapangidwa kudzera muukadaulo wokonza zinthu zouma. Kampaniyo inati kugwiritsa ntchito ukadaulo wokonza zinthu zouma kumagwirizana kwambiri ndi ubwino wa chitsulo. Miyala yachitsulo yomwe ili m'dera la migodi ya Carajás ili ndi chitsulo chambiri (choposa 65%), ndipo kukonzaku kumafunika kuphwanyidwa ndikusefedwa malinga ndi kukula kwa tinthu tating'onoting'ono.
Kampani ya Vale yapanga ukadaulo wosiyana wa maginito wouma wa miyala yosalala, womwe wagwiritsidwa ntchito pafakitale yoyesera ku Minas Gerais. Vale imagwiritsa ntchito ukadaulo uwu pokonza miyala yachitsulo yotsika mtengo. Fakitale yoyamba yamalonda idzagwiritsidwa ntchito ku Davarren mu 2023. Vale adati fakitaleyi idzakhala ndi mphamvu yopangira matani 1.5 miliyoni pachaka, ndipo ndalama zonse zomwe zayikidwa zikuyembekezeka kukhala US $150 miliyoni. Kuphatikiza apo, Vale yatsegula fakitale imodzi yosefera matope m'dera la migodi ya Great Varjin, ndipo ikukonzekera kutsegula mafakitale ena atatu osefera matope m'gawo loyamba la 2022, lomwe limodzi lili m'dera la migodi ya Brucutu ndipo awiri ali ku Iraq.
