Mu minsi ishize, umunyamakuru wo mu Bushinwa Metallurgical News yamenyeye muri Vale ko nyuma y'imyaka 7 y'ubushakashatsi n'ishoramari rya miliyoni 50 z'ama-reais (hafi $ 878.900), iyi sosiyete yateje imbere uburyo bwo gukora amabuye y'agaciro bwiza kandi butuma habaho iterambere rirambye. Vale yakoresheje ubu buryo bwo gukora amabuye y'agaciro mu gace isosiyete ikoreramo amabuye y'agaciro i Minas Gerais, muri Brezili, kandi ihindura uburyo bwo gutunganya amabuye y'agaciro bwasabaga ikoreshwa ry'ingomero cyangwa uburyo bwo kuyashyiramo amabuye y'agaciro meza. Ibicuruzwa by'amabuye y'agaciro bikorwa n'iyi nzira bishobora gukoreshwa mu nganda z'ubwubatsi.
Birumvikana ko kugeza ubu, Vale imaze gutunganya no gukora toni zigera ku 250.000 z'umucanga w'amabuye y'agaciro mwiza, ufite silicon nyinshi, icyuma gito cyane, hamwe n'ubunini bw'ibinyabutabire n'ingano y'uduce. Vale irateganya kugurisha cyangwa gutanga umusaruro wo gukora sima, sima, sima cyangwa se kugira ngo imihanda ikoreshwe.
Marcello Spinelli, Visi Perezida Mukuru w’Ubucuruzi bw’Amabuye y’Iron bwa Vale, yagize ati: “Hari ugushaka umucanga mwinshi mu nganda z’ubwubatsi. Ibicuruzwa byacu by’amabuye y’agaciro bitanga amahitamo yizewe ku nganda z’ubwubatsi, mu gihe bigabanya ingaruka mbi ziterwa no gutunganya amasafuriya. Ingaruka mbi ziterwa n’ibyo.”
Dukurikije imibare y’Umuryango w’Abibumbye, umucanga ukenerwa buri mwaka ku isi uri hagati ya toni miliyari 40 na miliyari 50. Umucanga wabaye umutungo kamere ufite ingano nini y’amazi acukurwa n’abantu. Uyu mucanga w’amabuye y’agaciro wa Vale ukomoka ku mucanga w’icyuma. Amabuye y’agaciro ashobora guhinduka amabuye y’icyuma nyuma y’ibikorwa bitandukanye nko gusya, gupima, gusya no kuyatunganya mu ruganda. Mu buryo busanzwe bwo kuyatunganya, ibintu bikomoka ku mabuye y’agaciro bizaba amatongo, agomba gutabwa mu ngomero cyangwa mu mifuka. Isosiyete yongera gutunganya ibintu bikomoka ku mabuye y’agaciro mu cyiciro cyo kuyatunganya kugeza igihe yujuje ibisabwa kandi akaba umucanga w’amabuye y’agaciro mwiza. Vale yavuze ko hakoreshejwe uburyo bwo guhindura amatongo mo amabuye y’agaciro meza, buri toni y’ibikomoka ku mabuye y’agaciro ikorwa ishobora kugabanya toni 1 y’amatongo. Bivugwa ko abashakashatsi bo mu Kigo cy’Ubucukuzi bw’Amabuye y’agaciro burambye muri Kaminuza ya Queensland muri Ositaraliya na Kaminuza ya Geneva mu Busuwisi ubu barimo gukora ubushakashatsi bwigenga kugira ngo basesengure imiterere y’ibikomoka ku mucanga w’amabuye y’agaciro bya Vale kugira ngo basobanukirwe niba koko bishobora kuba ubundi buryo burambye bwo gusimbura umucanga. Kandi bigabanya cyane ingano y’imyanda iterwa n’ibikorwa by’ubucukuzi bw’amabuye y’agaciro.
Jefferson Corraide, Umuyobozi Mukuru w’ishami rishinzwe ibikorwa bya Brucutu na Agualimpa muri Vale, yagize ati: “Ubu bwoko bw’ibikomoka ku mabuye y’agaciro ni ibikomoka ku bimera. Ibikomoka ku mabuye y’agaciro byose bitunganywa hakoreshejwe uburyo bwa fiziki. Imiterere y’ibinyabutabire mu bikoresho fatizo ntiyigeze ihinduka mu gihe cyo kubitunganya, kandi ibyo bicuruzwa ntabwo ari uburozi kandi nta ngaruka mbi bifite.”
Vale yavuze ko iteganya kugurisha cyangwa gutanga toni zirenga miliyoni imwe z'ibikomoka kuri ubwo butare mu 2022, no kongera umusaruro w'ibikomoka kuri ubwo butare ukagera kuri toni miliyoni 2 mu 2023. Bivugwa ko abaguzi b'iki gicuruzwa biteganijwe ko bazaturuka mu turere tune two muri Brezili, Minas Gerais, Espirito Santo, Sao Paulo na Brasilia.
“Twiteguye kwagura isoko ry’ibikomoka ku mucanga w’amabuye y’agaciro guhera mu 2023, kandi kuri ibi twashyizeho itsinda ryihariye ryo gukora ubu bucuruzi bushya.” Ibi byavuzwe na Rogério Nogueira, umuyobozi w’isoko ry’amabuye y’agaciro rya Vale.
“Kuri ubu, utundi duce ducukura amabuye y’agaciro muri Minas Gerais natwo turimo gutegura gahunda zitandukanye zo gukoresha ubu buryo bwo gukora. Byongeye kandi, turimo gukorana n’ibigo byinshi by’ubushakashatsi kugira ngo duteze imbere ibisubizo bishya kandi twiyemeje gukoresha neza icyuma. Amabuye y’agaciro atanga ibitekerezo bishya.” Ibi byavuzwe na André Vilhena, umuyobozi w’ubucuruzi wa Vale. Uretse gukoresha ibikorwa remezo biriho mu gace gacukurwamo amabuye y’agaciro, Vale yanashyizeho by’umwihariko umuyoboro munini w’ubwikorezi kugira ngo utware neza kandi mu buryo bworoshye ibicuruzwa by’umucanga w’amabuye y’agaciro mu ntara nyinshi muri Brezili. Villiena yongeyeho ati: “Icyo twibandaho ni ukureba ko ubucuruzi bw’amabuye y’agaciro burambye, kandi twizeye kugabanya ingaruka mbi ku bidukikije mu bikorwa by’ikigo binyuze muri ubu bucuruzi bushya.”
Vale imaze gukora ubushakashatsi ku bijyanye no gutunganya imiyoboro y'amabuye kuva mu 2014. Mu 2020, isosiyete yafunguye uruganda rwa mbere rw'igerageza rukoresha imiyoboro y'amabuye nk'ibikoresho by'ibanze mu gukora ibikoresho by'ubwubatsi - uruganda rw'amatafari ya Pico. Uru ruganda ruherereye mu gace ka Pico gacukurwamo amabuye y'agaciro muri Itabilito, Minas Gerais. Kuri ubu, Ikigo cya Leta gishinzwe Uburezi bwa Tekiniki cya Minas Gerais kirimo guteza imbere ubufatanye mu bya tekiniki n'uruganda rwa Pico Brick. Iki kigo cyohereje abashakashatsi barenga 10, barimo abarimu, abanyeshuri barangije kaminuza, abanyeshuri biga amasomo ya tekiniki n'abanyeshuri biga amasomo ya tekiniki, mu ruganda rwa Pico Brick kugira ngo bakore ubushakashatsi imbonankubone.
Uretse ubushakashatsi n'iterambere ry'ibikomoka ku bidukikije, Vale yanafashe ingamba zitandukanye kugira ngo igabanye umubare w'ibice by'ubucukuzi, bigatuma ibikorwa byo gucukura amabuye y'agaciro birushaho kurambye. Iyi sosiyete yiyemeje guteza imbere ikoranabuhanga ryo gutunganya amabuye y'agaciro adakenera amazi. Kuri ubu, hafi 70% by'ibikomoka ku byuma bya Vale bikorerwa hakoreshejwe ikoranabuhanga ryo gutunganya amabuye y'agaciro. Iyi sosiyete yavuze ko gukoresha ikoranabuhanga ryo gutunganya amabuye y'agaciro bifitanye isano rya hafi n'ubwiza bw'amabuye y'agaciro. Amabuye y'agaciro yo mu gace ka Carajás acukurwamo amabuye y'agaciro afite icyuma kinini (kirenga 65%), kandi gutunganya ayo mabuye bisaba gusa kuyasya no kuyasukura hakurikijwe ingano y'uduce.
Ishami rya Vale ryakoze ikoranabuhanga ryo gutandukanya amabuye y'agaciro yumye, ryakoreshejwe mu ruganda rw'igerageza ruri i Minas Gerais. Vale ikoresha iri koranabuhanga mu gutunganya amabuye y'agaciro yo mu rwego rwo hasi. Uruganda rwa mbere rw'ubucuruzi ruzakoreshwa mu gace ka Davarren mu 2023. Vale yavuze ko uru ruganda ruzaba rufite ubushobozi bwo gukora toni miliyoni 1.5 buri mwaka, kandi ishoramari ryose ryitezwe kuba miliyoni 150 z'amadolari y'Amerika. Byongeye kandi, Vale yafunguye uruganda rumwe rutunganya amabuye y'agaciro mu gace ka Great Varjin gacukura amabuye y'agaciro, kandi irateganya gufungura izindi nganda eshatu zitunganya amabuye y'agaciro mu gihembwe cya mbere cya 2022, muri zo rumwe ruri mu gace ka Brucutu gacukura amabuye y'agaciro naho ebyiri ziherereye muri Iraki. Agace ka Tagbila gacukura amabuye y'agaciro.
