Ngā Matū Tango Koura Matatau mō te Hangarau Whakarewa o Parahi
Te wikitoria i ngā Laterites uku-teitei me ngā sulfide ātete mai i Pará ki Minas Gerais
United Chemical E whakarato ana i te AuCyan™ Sodium Cyanide NaCN (≥98.3%) kua oti te whakarite, te AuCarb™ Gold Recovery Coconut Shell Activated Waro (≥99% Hardness), me te AuLeach™ Gold Leaching Agent (GDA) kore-mōrearea hei whakamana i te Heap leaching, te Vat leaching, te CIP, te CIL, me ngā mahi CIC puta noa i te rāngai keri maina o Brazil.
Te Wero o te Keri Maina o Brazil: Mai i te Amazon ki te Rino Tapawhā
He nui te wāhi o te koura o te ao e whakaputaina ana e Brazil, engari e hiahia ana te matawhenua motuhake ki te tino tika o te mahi whakarewa. I roto i te Quadrilátero Ferrífero (Iron Quadrangle) o Minas Gerais , ka tūtaki ngā mahi hohonu ki ngā konganuku sulfide uaua, ātete ki te cyanidation paerewa. I tua atu, i roto i te kawanatanga koura nui o Pará me te Amazon Basin o Tapajós , ka tūtaki ngā kamupene keri ki ngā arai whakahaere nui e tukatuka ana i ngā oneone laterite me te saprolite matotoru, whai uku, e tino whakaiti ana i te waro whakahohe.
Hei kaihanga ārahi i te ahumahi e whakahīhī ana ki te kaweake ki 77 + whenua i te ao, United Chemical e whakarato ana i ngā matū hanga-ake hei whakakore i ēnei here motuhake o Brazil. Hei tāpiri, e mōhio ana mātou ki ngā paerewa ESG pakari e whakatinanahia ana e IBAMA me te ANM, e tuku ana i ngā huarahi rerekē hou e tutuki ana i ngā whakaritenga. E tautoko katoa ana tā mātou putea i ngā Waro-i-te-Pūru (CIP), Waro-i-te-Whakarewa (CIL), Waro-i-te-Pou (CIC), Whakarewa puranga, me te Whakarewa poka.
Hei whakarite kia haumaru, kia kore e mutu ngā mekameka tuku, ka mahi motuhake mātou mā roto i ngā mahi kawe ipu moana. Ka mahi mātou i raro i ngā tikanga FOB (ngā tauranga Haina) me ngā tikanga CIF rānei ki ngā pokapū matua o Brazil pērā i te Tauranga o Santos, te Tauranga o Vila do Conde (Barcarena), me te Tauranga o Rio de Janeiro . Kāore mātou e whakamahi i te kawe tereina o te ao. Me te Rahinga Ota Iti rawa (MOQ) tino pakari o te 1x20' FCL , ka oati mātou i te whai huatanga utu tika mai i te wheketere mō ngā hoa keri arumoni katoa.
1. Te Wetewete i ngā Kohatu Uaua: Ngā Ārai Mahi i Brazil
Ngā Paruparu Laterite Uku-Teitei (Amazon)
Ka hangaia e ngā konganuku laterite o Amazon he penupenu matotoru rawa i roto i ngā tāke CIL/CIP. Mā te kutikuti miihini nui e hiahiatia ana hei whakaoho i tēnei paru matotoru ka pakaru te waro whakahohe paerewa hei puehu pai, ka puta te ngaronga koura kore e taea te hoki ki roto i ngā whare putunga para.
Ngā Pūkawai Ātete (Minas Gerais)
He maha ngā wā ka tūtaki ngā mahi hōhonu ki te arsenopyrite me te pyrrhotite. Ka mahi ēnei sulfide uaua ātete-waikura hei kaihoroi hāora me te cyanide (cyanicides), ka whakaroa i ngā tere whakarewa koura, ka pupuhi hoki i te matū OPEX.
Ngā Ture me ngā Ratonga Tino Pai a IBAMA
Ko te kawe i te cyanide DG Class 6.1 tino paitini ki roto i te awa o Amazon mā roto i ngā awa me ngā rori kāore i wharikitia me whai ratonga hōia utu nui, he whakaaetanga kaha, me te tirotiro taiao pakari. Me tere te hiahia ki ngā wāhi keri hei whakakapi i ngā mea e tutuki ana i te taiao, kāore hoki e mōrearea.
2. Te Tapatoru Koura: United ChemicalNgā Otinga mō Brazil
AuCyan™ Konutai Cyanide NaCN (≥98.3%)
Paerewa Parakore: ≥98.3%Hei wikitoria i ngā sulfide me ngā cyanide ātete-waikawa e kitea ana i roto i ngā maina hohonu o Brazil, ka tukuna e te AuCyan™ Sodium Cyanide NaCN te kaha matū kore e taea te whakarerekē. Ka tino oati mātou i te parakore iti rawa o te ≥98.3% (me ngā puranga whakaputa wheketere e whakamātautauhia ana i te 98.5%). I hangaia hei pereki ma tino pumau, ka whakarite a AuCyan™ i te tukunga kaha me te tere o ngā iona CN⁻, me te pupuri i te tere o te tangohanga ahakoa ka pau tetahi wāhanga o te otinga i ngā konganuku turanga.
Te Hanga Pūmautanga Teitei: Mā te konutai hauwai (NaOH) iti kāore i tauhohe ka whakaiti i te tauine kāore e hiahiatia i roto i ngā paipa CIL/CIP kaha.
Takai Haumaru-Moana: Kua tākaihia ki roto i ngā pahu rino hiri-ā-roto 50kg kua whakamanahia e te UN, i ngā pouaka rakau whakapakaritia rānei 1,000kg me ngā raina PE o roto, kia kore ai e mimiti te makuku i te wā e utaina ana i te Moana Ataratiki.
