Te wikitoria i ngā konganuku ātete i te Tonga o Āwherika: Ngā matū tukatuka koura CIL/CIP matua
Ko te Southern African Development Community (SADC) tonu te tino rangatira o te ao mō te hanga koura. Mai i ngā maina hohonu o Witwatersrand Basin o Āwherika ki te Tonga me ngā konganuku uaua o te Barberton Greenstone Belt , tae atu ki ngā mahi CIL e tere haere ana te horapa puta noa i Zimbabwe (pērā i a Gwanda me Kadoma ) me ngā mahi koraha o Namibia ( Navachab ), kāore he rite o te kanorau whakarewa o te rohe. Heoi, kei te tūtaki ngā kaiwhakahaere tipu hou o tēnei rohe ki te huihuinga o ngā wero hangarau, taiao, me te whakahaere rauemi.
E toru ngā ārai matua kua tautuhia e ngā Kaihanga Metallurgists Matua o Awherika ki te Tonga. Tuatahi, Ngā Ore Tino Ātete me te Tangohanga-Haerenga: He maha ngā putunga i Awherika ki te Tonga me Zimbabwe he nui ngā kukū o ngā sulfides, te arsenic, me ngā mea waro taiao . Ka ātete tonu ēnei ore ki te cyanidation paerewa, ā, ka tangohia wawetia te koura rewa mai i te ara iahiko, ka nui te ngaronga o ngā toenga wai. Tuarua, Ngā Ture ESG me te Wai Tino Nui: Ko te Ture Wai ā-Motu pakari o Awherika ki te Tonga me te korenga o te wai i Namibia e hiahia ana kia whakahaerea ngā toenga wai e pai ana mō te taiao. Ka tūtakihia ngā turuturu paitini ki te kati tonu i ngā mahi me ngā whiu kino. Tuatoru, Ko te Moemoeā Logistics Beitbridge: Ko ngā pokapū keri whenua i Zimbabwe me tua atu e whakawhirinaki nui ana ki te Tauranga o Durban (SA) me ngā tauranga o Beira mō ngā kawemai. Ko te kawe i ngā matū morearea Akomanga 6.1 (pēnei i te Sodium Cyanide ) me whakatere i te pou rohe rongonui o Beitbridge, i reira ka arahi ngā tirotiro morearea pakari ki ngā whakaroa maha-wiki, ka tūpono ka mutu ngā tipu.
United Chemical kua āta hangaia he huinga matū me te whatunga whakahaere hei whakaoti i te whārite o Āwherika ki te Tonga. Mā te whakarato i te waro tino mārō mō ngā tipu CIP nui, ngā wai whakapūkara kaha mō ngā konganuku whanariki, me ngā huarahi kē atu mō te tango kore-morearea e karo ana i ngā whakaroa rohe morearea, ka whakamanahia e mātou ngā kaihanga koura SADC ki te whakatutuki i ngā reiti whakaora kore e rite me te tutuki i ngā whakaritenga ESG katoa.
