Ua hana ʻo Vale ma kahi o 250,000 tons o nā huahana one hoʻomau, i hōʻoia ʻia e pani i ke one i ʻeli pinepine ʻia ma ke kānāwai.

Ma hope o 7 mau makahiki o ka noiʻi a me ka hoʻopukapuka kālā ma kahi o 50 miliona reais, ua hoʻomohala ʻo Vale i kahi kaʻina hana no nā huahana one kiʻekiʻe, hiki ke hoʻohana ʻia i ka ʻoihana kūkulu.Ua hoʻohana ka hui i kēia kaʻina hana huahana one i ka wahi hana o ka hao ma Minas Gerais, a hoʻololi i nā mea one i koi mua i ka hoʻohana ʻana i nā dams a i ʻole nā ​​​​ʻano hoʻopaʻa i nā huahana.ʻO ke kaʻina hana ma lalo o ka mana like like me ka hana ʻana o ka hao.I kēia makahiki, ua hana ka hui a hana i kahi o 250,000 tons o nā huahana one hoʻomau, a ke manaʻo nei ka hui e kūʻai aku a hāʻawi ʻia paha ia mau mea no ka hana ʻana i ka ʻuala, ka pāpaʻa a me ka sima a i ʻole no ka pave paving.

Ua ʻōlelo ʻo Mr. Marcello Spinelli, Hope Pelekikena Nui o Vale's Iron Ore Business, ʻo nā huahana one ka hopena o nā hana hana hoʻomau.Ua ʻōlelo ʻo ia: "Ua hoʻoikaika kēia papahana iā mākou e hana i kahi hoʻokele waiwai i loko.He koi nui no ke one ma ka ʻoihana kūkulu.Hāʻawi kā mākou huahana one i kahi koho kūpono i ka ʻoihana kūkulu, ʻoiai e hōʻemi ana i ka hopena o ke kaiapuni a me ka pilikanaka o ka hoʻolei ʻana i nā huelo.Hoʻohuli manaʻo."

ʻO Bulkoutu mining area paʻa one hoʻopaʻa pā hale

Wahi a nā United Nations, ʻo ka noi makahiki honua no ke one ma kahi o 40 a 50 biliona tons.Ua lilo ke one i kumu waiwai maoli i hoʻohana ʻia ma hope o ka wai, a ke hoʻohana ʻia nei kēia kumu waiwai me ke kānāwai ʻole a me ka ʻaihue ma ka pae honua.

Ua manaʻo ʻia nā huahana one hoʻomau o Vale he mea hoʻohua o ka hao.ʻO ka ʻeleʻele maka i ke ʻano o ka pōhaku i ʻeli ʻia mai ke ʻano maoli e lilo i mea hao ma hope o kekahi mau kaʻina hana kino e like me ka ʻoki ʻana, ka nānā ʻana, ka wili a me ka pōmaikaʻi i ka hale hana.Aia ka hana hou a Vale i ka hana hou ʻana i nā mea hao hao ma ka pae pōmaikaʻi a hiki i nā koi kūpono kūpono a lilo i huahana kalepa.Ma ke kaʻina hana hoʻomaikaʻi kuʻuna, e lilo kēia mau mea i huelo, i hoʻolei ʻia ma o ka hoʻohana ʻana i nā dams a i ʻole i loko o nā pahu.I kēia manawa, ʻo kēlā me kēia tona o nā hua one i hana ʻia, ʻo ia hoʻi ka emi ʻana o hoʻokahi tona o nā huelo.

ʻO nā huahana one i hana ʻia mai ke kaʻina hana hoʻoheheʻe hao he 100% hōʻoia.Loaʻa iā lākou ka maʻiʻo silika kiʻekiʻe a me ka haʻahaʻa haʻahaʻa haʻahaʻa o ka hao, a he kiʻekiʻe kemika like ʻole a me ka nui o ka nui o nā ʻāpana.Ua ʻōlelo ʻo Mr. Jefferson Corraide, ka luna hoʻokō o ka wahi hana hui ʻo Brucutu a me Agualimpa, ʻaʻole pilikia kēia ʻano huahana one."Hoʻohana maoli ʻia kā mākou huahana one e nā ʻano kino, a ʻaʻole i hoʻololi ʻia ke ʻano kemika o nā mea i ka wā o ka hana ʻana, no laila, ʻaʻohe mea ʻawaʻawa a maikaʻi ʻole nā ​​huahana."

ʻO ka hoʻohana ʻana i nā huahana one a Vale i loko o ka pahu a me ka mortar i hōʻoia ʻia e ka Brazilian Institute of Scientific Research (IPT), Falcão Bauer a me ConsultareLabCon, ʻekolu mau keʻena ʻoihana.

Ke alakaʻi nei nā mea noiʻi mai ka Institute of Sustainable Minerals ma ke Kulanui o Queensland ma Australia a me ke Kulanui o Geneva ma Switzerland i kahi noiʻi kūʻokoʻa no ka nānā ʻana i nā ʻano o nā huahana one Vale e hoʻomaopopo ai inā hiki i kēia mea kūkulu hale ʻē aʻe i loaʻa mai i ka ʻeleʻele ke lilo i kumu hoʻomau. one A hoʻemi nui i ka nui o nā ʻōpala i hana ʻia e nā hana eli.Hoʻohana ka poʻe noiʻi i ka huaʻōlelo "oresand" e pili ana i nā huahana one i loaʻa mai nā huahana a me ka hana ʻana.

pālākiō hana

Ua kūpaʻa ʻo Vale i ke kūʻai ʻana a hāʻawi ʻana paha i ʻoi aku ma mua o 1 miliona tons o nā huahana one e 2022. Hele mai kāna mau mea kūʻai mai ʻehā mau ʻāpana me Minas Gerais, Espirito Santo, Sao Paulo a me Brasilia.Wahi a ka hui ma ka makahiki 2023, e piʻi ka huahana o nā huahana one i 2 miliona tons.

"Ua mākaukau mākou e hoʻonui i ka mākeke noi o nā huahana one mai 2023. No kēia kumu, ua hoʻonohonoho mākou i kahi hui hoʻolaʻa e hoʻokomo i kēia ʻoihana hou.E hoʻohana lākou i ke kaʻina hana huahana one i ke kaʻina hana e kū nei e hoʻokō i ka noi mākeke.Ua ʻōlelo ʻo Mr. Rogério Nogueira, Luna Hoʻokele o Vale Iron Ore Marketing.

Ke hana nei ʻo Vale i nā huahana one ma ka mine Brucutu ma San Gonzalo de Abaisau, Minas Gerais, e kūʻai ʻia a hāʻawi ʻia paha.

Ke hana nei nā wahi ʻē aʻe ma Minas Gerais i nā hoʻoponopono kaiapuni a me nā mining e hoʻopili i nā kaʻina hana hana one."Ke hana nei kēia mau wahi mining i nā mea one me nā mea silika kiʻekiʻe, hiki ke hoʻohana ʻia i nā ʻoihana like ʻole.Ke hana pū nei mākou me nā hui he nui e like me nā kulanui, nā kikowaena noiʻi a me nā hui kūloko a me nā ʻāina ʻē e hoʻomohala i nā hopena hou e hāʻawi i nā huelo hao hou.Ala i waho.ʻO Mr. André Vilhena, ka luna ʻoihana hou o Vale i hoʻokūpaʻa.

Ma waho aʻe o ka hoʻohana ʻana i nā ʻenehana i loaʻa i ka ʻāina eli hao, ua hoʻomohala ʻo Vale i kahi ʻoihana kaʻa kaʻa me nā ala kaʻa a me nā alanui e lawe ai i nā huahana one i nā mokuʻāina he nui ma Brazil."ʻO kā mākou manaʻo nui e hōʻoia i ka hoʻomau o ka ʻoihana hao.Ma o kēia ʻoihana hou, manaʻolana mākou e hōʻemi i ka hopena o ke kaiapuni, ʻoiai e ʻimi ana i nā manawa e hoʻolaha i ka hana a hoʻonui i ka loaʻa kālā.Wahi a Mr. Verena.

huahana kaiaola

Ke alakaʻi nei ʻo Vale i ka noiʻi ʻana i nā huʻu mai ka makahiki 2014. I ka makahiki i hala, ua wehe ka hui i ka Puku Brick Factory, ʻo ia ka ʻoihana hoʻokele mua e hana i nā huahana kūkulu me ka hoʻohana ʻana i nā huelo mai nā hana mining ma ke ʻano he kumu kumu.Aia ka mea kanu ma ka wahi mining Pico ma Itabilito, Minas Gerais, a ke manaʻo nei e hoʻolaha i ka hoʻokele waiwai pōʻai i ka hana ʻana i ka hao hao.

Ua hoʻokumu ka Federal Center for Science and Technology Education o Minas Gerais a me ka Pico Brick Factory i ka hui ʻenehana a hoʻouna aku i nā mea noiʻi he 10 me nā kumu aʻoaʻo, nā ʻenehana ʻenehana, nā haumāna puka kula, puka lae a me nā haumāna papa ʻenehana i ka hale hana.I ka wā o ka hui ʻana, e hana mākou ma ka hale hana, a ʻaʻole kūʻai ʻia nā huahana i ka wā o ka noiʻi a me ka hoʻomohala ʻana i ka honua o waho.

Ke hui pū nei ʻo Vale me ka pā kula ʻo Itabira o Federal University of Itajuba e aʻo i ke ʻano o ka hoʻohana ʻana i nā huahana one no ka paving.Hoʻolālā ka hui e hāʻawi i nā huahana one i ka wahi kūloko no ka paʻi ʻana.

ʻOi aku ka hoʻomau ʻana o ka mining

Ma kahi o ka hoʻomohala ʻana i nā huahana kaiaola, ua hana ʻo Vale i nā hana ʻē aʻe e hōʻemi i nā huelo a hoʻoikaika 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 hoʻomaloʻo maloʻo ʻana, a e hoʻomau ʻia kēia ʻāpana ʻoiai ma hope o ka hoʻonui ʻia ʻana o ka mana hana makahiki i 400 miliona tons a hoʻokomo ʻia nā papahana hou.I ka makahiki 2015, ʻo ka hao hao i hana ʻia e ka hoʻoheheʻe maloʻo ʻana he 40% wale nō o ka nui o ka puka.

Inā hiki ke hoʻohana ʻia ka hana maloʻo e pili ana i ka maikaʻi o ka ʻili hao.ʻO ka hao hao ma Carajás he mea hao kiʻekiʻe (ma luna o 65%), a ʻo ke kaʻina hana wale nō e pono ke ʻoki ʻia a nānā ʻia e like me ka nui o ka ʻāpana.

ʻO ka awelika o ka hao o kekahi mau wahi eli ma Minas Gerais he 40%.ʻO ke ʻano hana maʻamau ka hoʻonui ʻana i ka hao o ka ʻai ma ka hoʻohui ʻana i ka wai i ka pōmaikaʻi.Hoʻopaʻa ʻia ka hapa nui o nā huelo i loko o nā pā huelo a i ʻole nā ​​lua.Ua hoʻohana ʻo Vale i kahi ʻenehana ʻē aʻe no ka hoʻomaikaʻi ʻana i ka ʻenehana hao haʻahaʻa, ʻo ia hoʻi ka hoʻokaʻawale magnetic maloʻo o ka ʻenehana maikaʻi (FDMS).ʻAʻole pono ka wai i ke kaʻina hoʻokaʻawale magnetic o ka hao hao, no laila ʻaʻohe pono e hoʻohana i nā dams tailings.

Ua hoʻomohala ʻia ka ʻenehana hoʻokaʻawale magnetic maloʻo no ka ʻeleʻele maikaʻi ma Brazil e NewSteel, i loaʻa iā Vale ma 2018, a ua hoʻohana ʻia i loko o kahi mea kanu pilot ma Minas Gerais.E hoʻohana ʻia ka mea kanu mua ma ka wahi hana ʻo Vargem Grande ma 2023. E loaʻa i ka mea kanu ka mana hana makahiki o 1.5 miliona tons a me ka huina kālā o US $ 150 miliona.

ʻO kekahi ʻenehana ʻē aʻe e hiki ke hōʻemi i ka noi no nā dams tailings, ʻo ia ke kānana i nā huelo a mālama iā lākou i loko o nā waihona maloʻo.Ma hope o ka hiki ʻana i ka 400 miliona tons i ka makahiki, ʻo ka hapa nui o ka 60 miliona tons (ʻo ka helu no 15% o ka nui o ka nui o ka hana) e hoʻohana i kēia ʻenehana e kānana a mālama i nā huelo.Ua wehe ʻo Vale i kahi mea kanu kānana tailings ma ka ʻāina mining nui ʻo Varzhin, a ke manaʻo nei e wehe i ʻekolu mau mea kanu kānana tailings i ka hapaha mua o 2022, aia kekahi o ia ma ka wahi mining Brucutu a ʻo nā mea ʻelua ʻē aʻe aia ma Itabira Mining wahi. .Ma hope o kēlā, ʻo ka hao hao i hana ʻia e ke kaʻina hana hoʻomaʻamaʻa pulu maʻamau e helu wale ʻia no 15% o ka nui o ka nui o ka hana, a e mālama ʻia nā huelo i hana ʻia i loko o nā pahu huelo a i ʻole nā ​​​​lua koʻu deactivated.
