Te Raupatu i ngā Kohatu Ātete i ngā Marae Koura o te Roto o Wikitōria: Ngā Tauhohenga Matatau mō te Keri i Āwherika ki te Rawhiti
Ko te rāngai keri maina o Āwherika ki te Rawhiti, e tautokona ana e te whitiki kōhatu matomato o te roto o Wikitōria o Tanzania, ā, e horapa ana ki ngā whenua teitei o Etiopia me Kenya, ko tētahi o ngā rohe koura tino hihiri o te ao. Mā te manaaki i ngā rawa Tier-1 pērā i te Maina Koura o Geita, North Mara, Bulyanhulu, me ngā kaupapa e haere ake nei pērā i a Tulu Kapi, he tino whakamiharo te pūmanawa o te rohe. Heoi, i te mea ka memeha haere ngā putunga waikura tata ki te mata, ka akiakihia ngā tohunga whakarewa o Āwherika ki te Rawhiti ki te tukatuka i ngā konganuku whanariki hohonu ake, tino uaua, ā, he ātete ki te werawera.
E toru ngā wero nui mō ngā kaiwhakahaere tipu CIL/CIP i te tukatuka i ēnei konganuku hōhonu o Āwherika ki te Rāwhiti. tuatahi, te āhua kino o te "whakangaromanga hapu" o te rohe waroko ngā konganuku hinu, e mimiti noa ana i te koura kua rewa i mua i te taea te tango mai. tuarua, te whakanui ake i te tirotiro taiao huri noa i ngā wai tiritahi o te roto o Wikitōria, te wāhi e tūpono ana te mōrearea o tina he nui te whiu mō te tukunga paru. tuatoru, ngā ara mahi uaua o uta mai i ngā Tauranga o Dar es Salaam me Mombasa, te wāhi e hiahiatia ana he takai matū e taea ai te tu atu i te wiri nui me te haumākū mō ngā mano kiromita o ngā rori taratara, kore-whaikiri.
United Chemical kua whakawhanake i tētahi huinga matū whakarewa kua whakaritea kia taea ai te wikitoria i ēnei arai o Āwherika ki te Rawhiti. Mā te arotau i te tere o te tango wai, te whakahaere i te reihi mimiti, me te whakarato i ngā huarahi kē atu e rite ana ki te ESG, ka whakarite mātou kia mau tonu te hua whakaora nui o tō tipu ahakoa te matatini o te whenua me te āhua whenua uaua.
Ngā Hua Whakaora Koura Matua i Whakaritea mō Āwherika ki te Rawhiti
AuCyan™ Konutai Cyanide NaCN (≥98.3%)
Ko te kawe i ngā taonga morearea mai i Dar es Salaam ki ngā wāhi maina tawhiti o Tanzania, o Rwanda rānei, me tino tika te takai. Ka pakaru ngā pahu iti iho i te paerewa i ngā rori tuawhenua taratara. Hei tāpiri, ko te nui o te konganuku taketake (pērā i te parahi) i roto i ētahi o ngā kōhatu matomato o Āwherika ki te Rawhiti ka tere te pau o te cyanide kounga iti. AuCyan™ e whakatau ana i ngā take e rua.
Te Tino Parakore mō ngā Kohatu Whakamātao: I te taurangi parakore ≥98.3%, ka whakarite a AuCyan™ i te whakaputanga tino kukū o te cyanide kore utu hohe (CN-).

Ngā tuhinga tino tika: Ko ngā matū kawemai ki Āwherika ki te Rāwhiti me whakamana i mua i te kaweake (pēnei i te PVOC/CoC). Ka whakahaerehia e mātou ngā tirotiro motuhake katoa a te SGS/Bureau Veritas i te wāhi taketake, kia kore ai he waku e pā ki ō kaihoko tuku taonga ā-rohe i te taenga mai o te kaipuke.
Whakamātauria te Mahi a ō Kohatu o Āwherika ki te Rawhiti
Ehara i te mea ko ngā matū anake tā mātou e hoko ana; engari ka whakaratohia e mātou he tino māramatanga mō te mahi whakarewa. Ka tono mātou ki ngā Kaiwhakahaere Hanga me ngā Kaimahi Whakarewa Matua puta noa i Tanzania, Etiopia, me Kenya kia tono mai i ngā tauira taiwhanga kore utu. Whakahaerehia ngā whakamātautau hurihuri pounamu me te mimiti tika i roto i tō ake taiwhanga, ā, mātakitaki i ngā raraunga.
Tonoa he Tauira Taiwhanga Koreutu InaianeiNgā Pātai Auau: Te Mahi Whakarewa Koura i Āwherika ki te Rawhiti
1. Me pēhea te ārai a AuCarb™ i te tango i te hinu i roto i ngā kōhatu matomato o Tanzania?
He maha ngā konganuku i roto i te whitiki kōhatu matomato o te roto o Wikitōria kei roto te waro tūturu e "kapo" ana i te koura i te wā e tangohia ana te koura. Waro Whakahohe Anga Kokonati AuCarb™ He hanganga macroporous tino pai rawa atu tēnei e tuku ana i te kaha mimiti tino kaha. Ka utaina e ia te matatini [Au(CN)₂]⁻ kia tere ake i te waro o te konganuku taketake, kia tino eke ai te koura ki tō ara iahiko whakaputanga, kaua ki ō toenga.
2. He haumaru te AuLeach™ GDA mō ngā mahi tata ki te awaawa o te roto o Wikitōria?
Te tino. Kaihoko Whakarewa Koura AuLeach™ kua whakamanahia puta noa i te ao he kore-morearea. Mō ngā maina e mahi tata ana ki ngā wāhi tairongo taiao pērā i te roto o Wikitōria, ka whakakapia ngā mea paitini konutai Cyanide Mā te AuLeach™ ka tino whakaitihia te mōrearea ā-taiao o te waipuke o te TSF (Tailings Storage Facility), ka whakarite kia tino tutukihia ngā whakaritenga ESG me te tiaki i ngā puna wai o te rohe.
3. He aha te mea e pai ai a AuCyan™ mō te haerenga roa ki uta mai i Dar es Salaam?
Ka taea e ngā waka uta puta noa i Āwherika ki te Rawhiti te whakararu i ngā utanga ki ngā wiri nui i runga i ngā rori kāore i wharikitia, me te haumākū nui o te ekueta. AuCyan™ NaCN kua whakamaua ki roto i ngā pūwero maitai taumaha kua whakamanahia e te UN me ngā arai polymer maha kua hiritia ki te wera, kia kore ai e uru te makuku, e pakaru rānei i te haerenga uaua ki tō papa maina.
4. Me whai taputapu hou a AuLeach™ mēnā kei te whakamahi tātou i te NaCN i tēnei wā?
Kāore e hiahiatia he whakapaunga whakapaipai. AuLeach™ kua hangaia hei whakakapinga tika mō konutai cyanideKa taea e ngā kaiwhakahaere tipu o Āwherika ki te Rawhiti te whakauru i te AuLeach™ ki roto i ā rātou tāke whakaoho, ngā papa tākai puranga, ngā tautuhinga tākai poka rānei mā te whakamahi i ā rātou papu inenga me ngā ara iahiko mimiti waro o nāianei.
5. Me pēhea te whakapai ake i te parakore o AuCyan™ ≥98.3% i te tātā i roto i ngā konganuku whanariki ātete?
He maha ngā wā ka hiahiatia he tikanga horoi kaha mō ngā konganuku whanariki o Āwherika ki te Rawhiti. Ka whakaurua mai e te cyanide iti-kounga ngā poke ka tauhohe ki ngā konganuku taketake (pēnei i te parahi, te rino rānei), ka maumauria te matū. Ko te parakore kua whakamanahia ≥98.3% o AuCyan™ ka whakarite i te kukū tiketike o te cyanide kore utu hohe (CN-), ka tere ake te whakarewatanga me te whakaiti i te whakamahinga whānui o te matū.
6. He tere ake te whakawātea a AuLeach™ i ngā tari tāke i Mombasa me Dar es Salaam?
Ae. No te mea konutai cyanide He matū tino paitini te Akomanga 6.1, e hiahiatia ana he whakaaetanga haumarutanga whānui, he whakaaetanga taiao, me ngā kaitiaki pū i ngā tauranga o Āwherika ki te Rāwhiti. AuLeach™, nā te mea ehara i te mea morearea, ka tukatukahia hei utanga ahumahi whānui, ka karo i ēnei arai ture, ā, ka tere ake te taenga atu ki tō wheketere i roto i ngā wiki.
7. He pēhea te mahi a AuCarb™ i roto i te whakaoho i te paru CIL kiato-teitei?
I roto i ngā tipu Waro-i-te-Rohe (CIL) kaha te whakaputanga, ka pāngia te waro e te kutikuti ā-mīhini kaha. AuCarb™ ka whakahohehia mā te wera ki te pakeketanga tino nui o te ≥99%. Mā tēnei ka ārai i te pakaru o te waro ki ngā matūriki angiangi, ā, ka whakakorea te mōrearea o ngā matūriki koura e rere ana i roto i ngā mata i waenga i ngā wāhanga, ka ngaro ki ngā paru.
8. Kei te whakahaere koe i ngā tirotiro PVOC / CoC e hiahiatia ana mō Tanzania me Kenya?
Āe. Ka whakauruhia katoatia e mātou te hanganga ture o Āwherika ki te Rawhiti ki roto i ā mātou mahi whakahaere. Ka mahi tahi mātou me ngā tari rongonui o te ao (pēnei i a SGS, Bureau Veritas rānei) i te tauranga taketake hei whakarite i te Manatoko Kaweake-Mua o te Whakaritenga (PVOC) me te Tiwhikete Whakaritenga (CoC), kia kore ai he raruraru o te tukanga kawemai mō ō kaihoko tuku taonga ā-rohe.
9. Ka taea e mātou te tono tauira hei whakamātautau i runga i ā mātou konganuku o Etiopia, o Tanzania rānei?
Ae. Ka akiaki mātou i te whakatau kaupapa e ahu mai ana i ngā raraunga. Ka taea e ngā miihini whakarewa o Āwherika ki te Rawhiti te tono Ngā Tauira Whakamātautau Koreutu o AuCyan™, AuCarb™, AuLeach™ rānei. Ka tukuna tika atu ēnei ki tō taiwhanga papaanga kia taea ai e koe te whakahaere i ngā whakamātautau hurihuri pounamu taketake me te manatoko i ngā whakapainga whakaora i runga i tō kōtaha konganuku motuhake.
