"Ua mākaukau mākou e hoʻonui hou i ka mākeke noi o nā huahana one mineral mai 2023, a no kēia mea ua hoʻonohonoho mākou i kahi hui hoʻolaʻa e hana i kēia ʻoihana hou."wahi a Rogério Nogueira, ka luna hoʻokele o ka mākeke hao o Vale.
"I kēia manawa, ke hoʻomākaukau nei nā wahi ʻoihana ʻē aʻe ma Minas Gerais i kahi ʻano hoʻomākaukau no ka hoʻokomo ʻana i kēia kaʻina hana.Eia kekahi, ke hana pū nei mākou me kekahi mau keʻena noiʻi e hoʻomohala i nā hopena hou a paʻa i ka mālama pono ʻana i ka hao.Hāʻawi ka ʻili ore i nā manaʻo hou.

Ke alakaʻi nei ʻo Vale i ka noiʻi e pili ana i nā noi lapaʻau huelo mai 2014. I ka makahiki 2020, ua wehe ka hui i ka mea kanu pilote mua e hoʻohana ana i nā huelo ma ke ʻano he kumu kumu no ka hana ʻana i nā huahana kūkulu - ka hale hana pōhaku Pico.Aia ka mea kanu ma ka wahi mining Pico ma Itabilito, Minas Gerais.I kēia manawa, ke hoʻomohala nei ka Federal Technical Education Center o Minas Gerais i ka hana ʻenehana me ka Pico Brick Factory.Ua hoʻouna ke kikowaena ma mua o 10 mau mea noiʻi, me nā polopeka, nā haumāna puka, nā haumāna lae a me nā haumāna papa ʻenehana, i ka Pico Brick Factory e hana i ka noiʻi ma ke kino.
Ma kahi o ka noiʻi a me ka hoʻomohala ʻana i nā huahana kaiaola, ua lawe pū ʻo Vale i nā ʻano hana like ʻole e hōʻemi i ka nui o nā huelo, e hoʻomau i nā hana mining.Ua kūpaʻa ka hui i ka hoʻomohala ʻana i ka ʻenehana hana maloʻo ʻaʻole pono ka wai.I kēia manawa, ma kahi o 70% o nā huahana hao o Vale e hana ʻia ma o ka ʻenehana hana maloʻo.Ua'ōlelo ka hui e pili pono ana ka hoʻohanaʻana i kaʻenehana hana maloʻo i ka maikaʻi o ka hao hao.ʻO ka hao hao ma ka ʻāina mining Carajás he mea hao kiʻekiʻe (ma luna o 65%), a ʻo ka hana wale nō e pono e ʻoki ʻia a kānana ʻia e like me ka nui o ka ʻāpana.
