Te Whakarerekētanga o te Tukatuka Koura i Āwherika Waenganui: Ngā Tauhohenga Mahi-Tiketike
Kei te tere haere te whanaketanga o te whenua keri koura i Āwherika Waenga—e horapa ana i ngā rohe kōhatu matomato o te Democratic Republic of Congo (DRC) , ngā wāhi miihini e horapa haere ana i Cameroon , me ngā mahi hou i Gabon me te Central African Republic . Kei te piki haere ngā kaiwhakahaere mai i ngā tikanga mahi toi ki ngā whare tukatuka whakarewa matatau e kaha ana ki te whakahaere i ngā tana nui o ngā konganuku lateritic tuatahi me ngā konganuku kua pakaru.
Heoi, he rerekē ngā wero o te keri i roto i te Congo Basin. Tuatahi, te Āhuarangi o te Ngāherehere Ua Tropical: Ko te haumākū nui me te ua nui e hiahiatia ana he takai pakari, ātete ki te huarere hei oranga mō te haerenga moana me te rokiroki ki uta. Tuarua, Ngā Ore Tino Pakaru: Ka hangaia e ngā oneone laterite he paru matotoru i roto i ngā tāke, e hiahia ana ki ngā matū tino pakari e kore e pirau i raro i te whakaoho kaha. Tuatoru, Ngā Mahi Whānui: Me whai matū urutau ngā tohunga whakarewa e pai ana te mahi puta noa i te Waro-i-te-Pulp (CIP) , te Waro-i-te-Leach (CIL) , te Waro-i-te-Pou (CIC) , tae atu ki te Heap Leaching whānui me ngā whakaritenga Vat Leaching hanganga.
United Chemical ko te hoa mahi tino pai mō ngā kaihanga koura o Āwherika Waenganui. Ka tukuna e mātou he huinga whakauru o ngā matū kounga teitei i hangaia hei ārai i ngā āhuatanga werawera, hei whakahaere i ō tukanga kawemai, ā, hei whakanui ake i ngā hua o ō konganuku utu nui.
