Ngā Pātai Auau: Te Hanganga Metara me te Whakahaere Rauemi o Dominican
Kimihia ngā whakautu mārama, e arohia ana e ngā tohunga ki ngā pātai hangarau me ngā whakaritenga e pā ana ki ā mātou matū tango koura i te Dominican Republic.
1. Me pēhea te whakahaere a AuCyan™ i ngā konganuku whanariki ātete-waikura i te Dominican Republic?
Ka whakahaerea e AuCyan™ ngā konganuku sulfide ātete mā te tuku i te kukū parakore tino teitei (≥98.3%) o te Sodium cyanide hohe . Ko ngā konganuku i ngā rohe pēnei i a Pueblo Viejo me whai pre-oxidation (POX), ka waiho he paru tino kaha. Ka tere te pau o ngā tauhohenga parakore iti e ngā cyanicides e toe ana. Ko tā mātou parakore kua whakamanahia ≥98.3% ka whakarite kia nui rawa te toenga o ngā iona CN⁻ kore utu, kia mau tonu ai te tere me te whai hua o te whakarewatanga koura i muri i te waikura.
2. Ka ātete te takai AuCyan™ ki ngā awhiowhio o te Karipiana me te haumākū o te rohe pārūrū?
Āe, ka tiakina a AuCyan™ mai i te haumākū nui o te Karipiana mā te hanganga makuku tino iti (≤0.3%) me te takai kaweake motuhake kua whakamanahia e te UN. Ka tākaihia e mātou ā mātou pereki ki roto i ngā pahu maitai hiri-ā-ringa 50kg, i ngā pouaka rakau whakapakari 1,000kg rānei. Kei roto i ia waeine he arai Polyethylene (PE) taumaha, hiri-wera e ārai katoa ana i te makuku o te hau, e ārai ana i te waikura me te hau kore e puta mai i te hau ahakoa i ngā wā awhiowhio kino.
3. He aha te take he mea nui te pakeketanga ≥99% mō te waro whakahohe i roto i ngā paru i muri i te POX?
Mā te pakeketanga ≥99% ka ārai i te waro whakahohe kia pakaru ki te puehu angiangi e ngā paru tino whakakoi i puta mai i te Whakaora Pēhanga (POX). Mena he ngohengohe tō waro, ka hurihia e te whakaoho kaha o te impeller i roto i ngā tāke CIL, 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.
4. Ka taea e AuCarb™ te whakaiti i ngā pānga "whakangaromanga waro" i roto i ngā konganuku waro?
Ae, ka whakaitihia e AuCarb™ te tango i te koura i te wā e hapu ana mā roto i ōna kaha nui o te mimiti i te iodine me te CTC. He maha ngā waro taketake kei roto i ngā konganuku Dominican e mimiti wawe ana i te matatini koura-cyanide. Ko te whakahohenga pai o AuCarb™ ka tere ake te whakataetae ki tēnei mea waro taketake, ka tere te tango i te koura mai i te otinga i mua i te ngaronga.
5. Kei te whakarōpūtia te AuLeach™ GDA hei mea morearea mō te kawemai ki ngā tauranga Karipiana?
Kāo, kua whakarōpūtia mana a AuLeach™ puta noa i te ao hei matū Kore-Mōrearea. Ko te kawemai i te cyanide paitini DG Class 6.1 ki ngā whenua moutere pakarukaru te taiao he nui te tirotiro me te whakaroa. Ka taea te tuku i a AuLeach™ hei utanga whānui, ka tino māmā ake te whakawātea tikanga moana i Port Caucedo, ā, ka whakaitihia hoki ngā utu tutuki i ngā whakaritenga ESG.
6. He aha ngā momo konganuku Dominican ka taea te tukatuka mā te whakamahi i te AuLeach™?
He whānui rawa te whānuitanga o ngā tono a AuLeach™. E ai ki tana Pepa Raraunga Hangarau kua whakamanahia, 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-para me te puna/waka.
7. Me pēhea te whakamātautau a ngā taiwhanga whakarewa i te Dominican Republic 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.
8. 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.
9. Ko ēhea ngā tauranga moana e whakamahia ana e koe mō ngā tuku CIF ki te Dominican Republic?
Ko te tauranga o Caucedo me te tauranga o Haina te nuinga o ā mātou mahi mō ngā tukunga kaipuke CIF. Ko te tauranga o Caucedo te pokapū arumoni moana hohonu matua o te motu, e tuku ana i te hanganga whakawātea tikanga tino pumau mō ngā matū ahumahi. Kia whakawāteatia, ka whakahaerehia ngā taraka uta e tō kaihoko whakahaere taonga ā-rohe kua tohua.
10. Kei te whakarato koe i ngā uta rererangi, i ngā tereina whakawhiti-rohe rānei mō te kawe matū papatipu?
Kāo, ka tino āraia e mātou te whakamahinga o ngā utanga rererangi me ngā tereina o te ao mō ngā kaweake matū nui. Nā te kaha o ngā ture haumaru o te ao e whakahaere ana i te nekehanga o ngā matū keri, ka tiakina e mātou tā mātou mekameka tuku mā te tuku ipu moana tino haumaru (FOB, CIF rānei).
11. He aha te rahinga ota iti rawa (MOQ) mō te kaweake ki te Dominican Republic?
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 puta noa i te moana.
12. 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.
