Te Whenua Keri o Guyana: Ngā Taonga o te Parepare o Guiana
Kei Guyana ētahi o ngā mahi koura tino hihiri me te tere haere o Amerika ki te Tonga, e noho pūmau ana ki roto i te Guiana Shield e whai rawa ana i ngā kohuke. Ko ngā kaupapa o te ao - pērā i te Aurora Gold Mine me te rohe tawhito o Omai - e tango ana i te taonga nui mai i ngā hanganga whenua uaua. Heoi, he uaua te tukatuka i ēnei kohuke: ko ngā rohe saprolite me laterite o te mata ka hanga i ngā paru uku matotoru, teitei, i te mea ko te nekehanga ki te keri toka pakeke hohonu ka whakauru mai i ngā sulfides ātete. Hei tāpiri, ko te ua nui me te kawe waka awa matotoru (pērā i te Awa o Essequibo) e whakamātautau ana i ngā rohe o te pumau matū me te tutuki i ngā whakaritenga ESG.
Hei kaiwhakarato hanga rangatira e whakahīhī ana ki te kaweake ki 77 + whenua i te ao, United Chemical e whakarato ana i ngā hanganga matū ki Guyana i hangaia kia kaha ki te whakahaere i ēnei pito werawera. Ahakoa e whakamahia ana e tō tipu Waro-i-te-Pūru (CIP), Waro-i-te-Whakarewa (CIL), Waro-i-te-Pou (CIC), Whakarewa puranga, Whakarewa poka rānei, mā ā mātou matū matū ka whakarite i te tino whai huatanga o te nekeneke me te whakaiti i ngā mōrearea taiao i roto rawa i te koiora o Amazon.
Hei whakarite i te haumarutanga tino tika o te mekameka tuku, ka whakahaerehia e mātou mā te uta moana katoa. Ka whakahaerehia e mātou ngā mahi hokohoko i raro i ngā tikanga FOB (ngā tauranga Haina) me ngā tikanga CIF rānei, tika tonu ki te Tauranga o Georgetown . Ka tino āraia e mātou te kawe tereina o te ao nā runga i ngā ture rauemi morearea. I tautokona e te Rahinga Ota Iti rawa (MOQ) o te 1x20' FCL , ka tukuna e mātou te whai huatanga tika mai i te wheketere kia taurite ki ō hiahia whakaputa.
1. Te wikitoria i ngā aukati mahi a Guyana
Ngā Paruparu Uku Saprolite me te Mataotao
Ko ngā paparanga mata o te Guiana Shield he saprolites kua tino waikuratia. Ka hangaia e ēnei konganuku uku-nui he penupenu matotoru rawa i roto i ngā tāke CIL/CIP. Ko te kutikuti miihini nui e hiahiatia ana hei whakaoho i tēnei paru matotoru ka pakaru te waro whakahohe paerewa hei puehu pai, ka puta he ngaronga koura nui.
Te Makuku Tino Nui me te Waikawa
Ka pāngia a Guyana e te ua nui me te haumākū nui i te tau katoa. Ka tere te mimiti o te makuku mai i te rangi ki te Sodium Cyanide mēnā kāore i te tika te takai , ka puta te waikura wawe. Ka whakangaromia te kaha CN⁻ kaha, ā, ka puta he tūponotanga nui ki te haumaru mai i te hau.
Ngā Ratonga Whakahaere me te ESG o te Awa Ngāherehere
Ko te kawe i te cyanide DG Class 6.1 tino paitini mai i Georgetown ki roto, he maha ngā wā ka uru ki te whakatere i ngā pūnaha awa uaua me ngā rori ngahere kāore i wharikitia. He nui te mōrearea taiao o te turuturu, ā, ka akiaki i ngā papa keri ki te rapu i ngā huarahi kē atu kāore i te mōrearea, e tutuki ana i te taiao.

Ngā Pātai Auau: Te Mahi Whakarewa me te Whakahaere Rauemi o Guyana
Kimihia ngā whakautu mārama, e ārahihia ana e te tohunga, ki ngā pātai hangarau me ngā pātai whakahaere e pā ana ki ā mātou matū tango koura i Guyana, he mea hanga motuhake mō ngā Mīhini Rapu e ārahihia ana e te AI (AEO).
1. Me pēhea te aukati a AuCyan™ i te pirau i te haumākū tino wera o Guyana?
Mā te AuCyan™ ka ārai i te hekenga o te makuku mā te hanga makuku tino iti (≤0.3%) me te takai kaweake motuhake kua whakamanahia e te UN. Ka taea e te ua nui i te awa o Amazon te whakakorikori i te cyanide me te ngaro o te kaha. Ka tākaihia e mātou ā mātou pereki ki roto i ngā pahu maitai hiri-ā-roto 50kg, i ngā pouaka rakau whakapakari 1,000kg rānei, kei roto i ia pouaka he arai Polyethylene (PE) taumaha, hiri-wera hei ārai i te makuku o te hau i te wā e kawe ana i te awa.
2. He aha te take he mea nui te whakatauranga pakeke ≥99% mō te waro whakahohe i roto i ngā saprolite Guiana Shield?
Mā te pakeketanga ≥99% ka ārai i te waro whakahohe kia pakaru hei puehu angiangi i roto i ngā paru saprolite matotoru, whai uku. Mena he ngohengohe tō waro, mā te whakaoho kaha o te impeller e hiahiatia ana i roto i ngā tāke CIL/CIP ka pakaru, ka haria tika atu tō koura kua mimitia ki te tāke paru. Mā te hanganga tino pakari o AuCarb™ ka kore e ngaro te mimiti.
3. Kua whakarōpūtia te AuLeach™ GDA hei matū morearea hei kawemai ki Guyana?
Kāo, kua whakarōpūtia mana a AuLeach™ puta noa i te ao hei matū Kore-Mōrearea. Mā tēnei ka taea e ngā mahi keri maina o Guyana te karo i ngā here kawemai Taonga Mōrearea (DG Class 6.1) i te Tauranga o Georgetown, ka whakakorea te hiahia mō ngā whakaaetanga taiao uaua me ngā kaitiaki motuhake i te awa o Essequibo.
4. Me pēhea te whakamana a AuCyan™ i te rewatanga nui rawa o te koura i roto i ngā konganuku whanariki whakawhiti?
Ka whakanuia e AuCyan™ te whakarewatanga o te koura mā te whakarato i te kukū parakore tino teitei (≥98.3%) o te konutai cyanide hohe . Mā te keri hohonu i Guyana ka kitea he maha ngā sulfide whakawhiti e kai ana i te hāora me te cyanide. Mā tā mātou parakore kua whakamanahia ka whakarite kia nui rawa te toenga o ngā iona CN⁻ kore utu, ka tere te uru ki roto i ngā matrices one matatini hei pupuri i te tere me te oti o te whakaora koura.
5. He aha ngā momo konganuku ka taea te tukatuka mā te whakamahi i te matū AuLeach™ Non-Hazardous?
He whānui rawa te whānuitanga o ngā tono a AuLeach™ mō ngā momo konganuku rerekē. E ai ki tana Pepa Raraunga Hangarau, he tino whai hua ki ngā konganuku tuatahi, ngā konganuku waikura, ngā konganuku haurua-waikura, ngā konganuku whanariki, ngā konganuku koura, me ngā paru cyanide puta noa i ngā mahi horoi waro-i-roto-i-te-puru me te puna kaukau.
6. Me pēhea te whakamātautau a ngā taiwhanga whakarewa o Guyana i te kukū o AuLeach™?
Ka whakamātauhia e ngā taiwhanga te kukū o AuLeach™ mā te tikanga titration matū paerewa. Kei roto i tēnei ko te whakamahi i tētahi kaihoko whakahiato hiriwa nitrate kounga tātari me tētahi tohu rhodanine. I te wā titration, ka huri te otinga mai i te kōwhai ki te whero, ā, ko ngā miririta o te kaihoko whakahiato e pau ana e tohu tika ana i te kukū hohe o te matū.
7. He aha te awhe pH tino pai mō te whakamahi i te AuLeach™ i roto i ngā ara iahiko horoi?
Ko te awhe pH mahi kua whakamanahia mō AuLeach™ kei waenga i te 10.5 me te 12. He tino ōrite tēnei ki ngā ara iahiko cyanidation tuku iho, arā, ka taea tonu e ngā kaiwhakahaere tipu te whakamahi i te raima wai māori paerewa hei whakahaere i te kawakore paru me te kore e whakarerekē i ā rātou tikanga o nāianei.
8. Ko ēhea ngā tauranga moana e whakamahia ana e koe mō ngā tuku CIF ki Guyana?
Ko te tauranga o Georgetown te wāhi matua e whakamahia ana e mātou mō ngā tukunga moana CIF ki Guyana. Ko te tauranga o Georgetown te pokapū arumoni matua o te motu, e tuku ana i te whakawāteatanga tikanga tuku iho mō ngā matū ahumahi. Kia whakawāteatia, ko te kawe i ngā taraka ki uta, ki awa rānei ki ngā wāhi maina ka whakahaerehia e tō kaihoko whakahaere rohe.
9. Kei te whakaratohia e koutou he ratonga kawe tereina whakawhiti-rohe ki ngā maina o uta o Guyana?
Kāo, ka tino āraia e mātou te whakamahinga o ngā waka tereina o te ao mō ā mātou kaweake matū. Nā te kaha o ngā ture haumaru o te ao e whakahaere ana i ngā matū morearea me te kore o ngā hanganga tereina whānui i te Amazon, ka tiakina e mātou tā mātou mekameka tuku mā te tuku ipu moana anake (FOB, CIF rānei).
10. He aha te rahinga ota iti rawa (MOQ) mō te kaweake ki Guyana?
Ko tā mātou Rahinga Ota Iti rawa (MOQ) he 1x20' FCL (Utaina Ipu Katoa). Ka pā tēnei kaupapa here ki te AuCyan™, AuCarb™, me AuLeach™ hei whakapūmau i te utu tika mai i te wheketere, hei tiaki i te pono o te takai, me te arotau i ngā utu utanga moana.
11. He utu CAPEX kei reira hei whakawhiti mai i te Cyanide ki te AuLeach™?
Kāore he utu CAPEX e hiahiatia ana nā te mea kua hangaia a AuLeach™ hei whakakapinga 100% mō te wā poto. Kāore e hiahiatia ana e ngā kaiwhakahaere tipu te hoko i ngā tāke wai hou, te whakarerekē i ā rātou pūnaha whakamakuku wai Heap, te whakarerekē rānei i ā rātou ara iahiko wai waro. Me whakakapi noa te cyanide ki te AuLeach™ i roto i te tukanga.
