Nō nā tata nei, i rongo te kairīpoata o China Metallurgical News i a Vale, whai muri i te 7 tau o te rangahau me te haumitanga o te 50 miriona reais (tata ki te US$878,900), kua angitu te kamupene ki te whakawhanake i tētahi tukanga whakaputa konganuku kounga teitei e whai hua ana mō te whanaketanga pumau. Kua whakamahia e Vale tēnei tukanga whakaputa ki te rohe mahi konganuku rino a te kamupene i Minas Gerais, Brazil, ā, kua hurihia ngā tukatuka paru i hiahiatia ai te whakamahi i ngā tāke, i ngā tikanga whakarārangi rānei hei hua konganuku kounga teitei. Ka taea te whakamahi i ngā hua konganuku i hangaia e tēnei tukanga i roto i te umanga hanga.
E mōhiotia ana tae noa mai ki tēnei wā, kua tukatukahia, kua whakaputaina hoki e Vale te 250,000 tana o ēnei hua onepu kohuke kounga teitei, he nui te ihirangi silicon, he iti rawa te ihirangi rino, ā, he teitei te ōritetanga matū me te rahi o te matūriki. Kei te whakamahere a Vale ki te hoko, ki te koha rānei i te hua hei hanga raima, moata, sima, hei hanga rānei i ngā rori.
I mea atu a Marcello Spinelli, te Tumuaki Tuarua o te Pakihi Rino o Vale: "He nui te hiahia mō te onepu i roto i te umanga hanga. He whiringa pono ā mātou hua kohuke mō te umanga hanga, me te whakaiti i te pānga ki te taiao o te maimoatanga paru. Ko te pānga kino i puta mai."
E ai ki ngā tatauranga a te Kotahitanga o ngā Whenua o te Ao, ko te hiahia ā-tau mō te onepu kei waenganui i te 40 piriona tāne me te 50 piriona tāne. Kua riro te onepu hei rauemi taiao me te nui rawa o te tangohanga a te tangata i muri i te wai. Ko tēnei hua onepu kohuke o Vale i ahu mai i te hua taha o te rino. Ka taea e te konganuku mata te huri hei konganuku rino i muri i ētahi tukanga pēnei i te kuru, te tātari, te huri me te whakapai ake i roto i te wheketere. I roto i te tukanga whakapai ake tuku iho, ka huri ngā hua taha hei paru, me maka atu mā roto i ngā tāke, i roto rānei i ngā puranga. Ka tukatuka anō te kamupene i ngā hua taha o te rino i te wāhanga whakapai ake kia tutuki rā anō ngā whakaritenga kounga, ā, ka noho hei hua onepu kohuke kounga teitei. I kī a Vale mā te whakamahi i te tukanga huri i ngā paru ki te konganuku kounga teitei, ka taea e ia tana hua konganuku ka puta te whakaiti i te 1 tāne o ngā paru. E ai ki ngā pūrongo, kei te whakahaerehia e ngā kairangahau o te Institute of Sustainable Minerals i te Whare Wānanga o Queensland i Ahitereiria me te Whare Wānanga o Geneva i Switzerland tētahi rangahau motuhake hei tātari i ngā āhuatanga o ngā hua onepu kohuke a Vale kia mārama ai mēnā ka taea e rātou te noho hei huarahi tauwhiro hei whakakapi i te onepu. Ā, ka whakaiti nui i te nui o ngā para e puta mai ana i ngā mahi keri maina.
I mea atu a Jefferson Corraide, te Kaiwhakahaere Matua o te rohe mahi whakauru o Brucutu me Agualimpa o Vale: "He tino hua matomato tēnei momo hua kohuke. Ka tukatukahia ngā hua kohuke katoa mā ngā tikanga ā-tinana. Kāore i rerekē te hanganga matū o ngā rauemi mata i te wā e tukatukahia ana, ā, kāore he paitini, he kino hoki te hua."
I kī a Vale kei te whakamahere rātou ki te hoko atu, ki te koha rānei i te neke atu i te 1 miriona tana o aua hua kohuke i te tau 2022, ā, ka whakapiki ake i te putanga o ngā hua kohuke ki te 2 miriona tana i te tau 2023. E ai ki ngā pūrongo, e tūmanakohia ana ka ahu mai ngā kaihoko o tēnei hua i ngā rohe e whā o Brazil, arā, ko Minas Gerais, ko Espirito Santo, ko Sao Paulo me Brasilia.
"Kua rite mātou ki te whakawhānui ake i te mākete tono mō ngā hua onepu kohuke mai i te tau 2023, ā, kua whakatūria e mātou he tīma motuhake hei whakahaere i tēnei pakihi hou," te kī a Rogério Nogueira, te kaiwhakahaere o te mākete rino o Vale.
"I tēnei wā, kei te whakarite hoki ētahi atu wāhi keri i Minas Gerais i ētahi raupapa whakaritenga mō te tango i tēnei tukanga whakaputa. Hei tāpiri, kei te mahi tahi mātou me ētahi whare rangahau ki te whakawhanake i ngā otinga hou, ā, e whakapau kaha ana mātou ki te tukatuka tika i te rino. Ka whakaratohia e ngā toenga o te rino ngā whakaaro hou," te kī a André Vilhena, te kaiwhakahaere pakihi o Vale. Haunga te whakamahi i ngā hanganga o nāianei i roto i te rohe keri rino, kua whakatū motuhake hoki a Vale i tētahi whatunga kawe nui hei kawe pai me te watea i ngā hua onepu kohuke pumau ki ngā whenua maha i Brazil. "Ko tā mātou arotahi he whakarite i te pumau o te pakihi rino, ā, ko tā mātou tumanako ka whakaitihia te tapuwae taiao o ngā mahi a te kamupene mā tēnei pakihi hou," te tāpiri a Villiena.
Mai i te tau 2014, kua whakahaerehia e Vale ngā rangahau mō ngā tono maimoatanga paru paru. I te tau 2020, i whakatuwheratia e te kamupene te wheketere whakamātautau tuatahi e whakamahi ana i ngā paru paru hei rauemi mata matua hei whakaputa hua hanga - te wheketere pereki Pico. Kei te rohe keri Pico i Itabilito, Minas Gerais te wheketere. I tēnei wā, kei te kaha te whakawhanake a te Pokapū Mātauranga Hangarau ā-Motu o Minas Gerais i te mahi tahi hangarau me te wheketere pereki Pico. Neke atu i te 10 ngā kairangahau i tukuna e te pokapū, tae atu ki ngā ahorangi, ngā ākonga paerua, ngā ākonga paetahi me ngā ākonga akoranga hangarau, ki te wheketere pereki Pico ki te whakahaere rangahau ā-kanohi.
Haunga te rangahau me te whakawhanake i ngā hua taiao, kua mahi a Vale i ētahi mahi hei whakaiti i te maha o ngā para, kia pumau ake ai ngā mahi keri. Kua whakapau kaha te kamupene ki te whakawhanake i te hangarau tukatuka maroke kāore e hiahiatia he wai. I tēnei wā, tata ki te 70% o ngā hua rino a Vale e whakaputaina ana mā te hangarau tukatuka maroke. I kī te kamupene he hononga tata te whakamahinga o te hangarau tukatuka maroke ki te kounga o te rino. He nui te ihirangi rino o te rino i te rohe keri o Carajás (neke atu i te 65%), ā, me kuru noa te tukatuka me te tātari kia rite ki te rahi o te matūriki.
Kua whakawhanakehia e te apiti o Vale tētahi hangarau wehewehe aukume maroke mō te konganuku pai, kua whakamahia i roto i tētahi tipu whakamātautau i Minas Gerais. Ka whakamahia e Vale tēnei hangarau ki te tukanga whakapai ake i te konganuku rino iti-kounga. Ka whakamahia te tipu arumoni tuatahi i te rohe whakahaere o Davarren i te tau 2023. I kī a Vale ka 1.5 miriona tana te kaha whakaputa ā-tau o te tipu, ā, e matapaetia ana ko te tapeke haumitanga ka eke ki te US$150 miriona. Hei tāpiri, kua whakatuwherahia e Vale tētahi tipu tātari para i te rohe keri o Great Varjin, ā, kei te whakamahere ia ki te whakatuwhera i ētahi atu tipu tātari para e toru i te hauwhā tuatahi o te tau 2022, kei te rohe keri o Brucutu tētahi, ā, kei Iraq ētahi e rua. Te rohe keri o Tagbila.
