Hoʻopili ʻia nā reagents i loko o nā pahu kila UN i hoʻopaʻa ʻia a kaupaona ʻia, a lawe ʻia ma o nā kaʻa lawe hazmat laikini pololei mai Durban Port a i nā hale kūʻai mine ma Johannesburg, Carletonville, a me Welkom.
6. Ua kūlike anei ʻo AuLeach™ me nā kaapuni elution a me electrowinning o ʻApelika Hema?
ʻAe loa. ʻAʻohe hoʻololi kālā e pono ai ʻo AuLeach™ GDA . Hoʻokumu ia i nā hui gula paʻa e hoʻopili pono ana ma luna o ke kalapona hoʻāla ʻia o ka pūpū niu a elute maʻemaʻe i nā mea kanu Anglo American a i ʻole Zadra elution a me electrowinning (EW) maʻamau.
7. Pehea ka hana a AuCyan™ i nā reactors leach ikaika kiʻekiʻe (HLR) e like me nā ʻōnaehana Acacia?
Pono nā reactors leaching ikaika kiʻekiʻe e hana ana i nā concentrates gula umekaumaha i nā reagents maʻemaʻe kiʻekiʻe. Hoʻoheheʻe koke a piha ʻo AuCyan™ (≥98.3%) , e hōʻoiaʻiʻo ana i ka hoʻoheheʻe ʻia ʻana o nā ʻāpana gula coarse a me nā mea maikaʻi i nā pōʻaiapuni leach reactor batch i loko o nā hola.
8. No ke aha e koho ai nā hale hana gula ʻApelika Hema i ke kalapona pūpū niu ma Indonesia ma mua o ke kalapona lanahu kūloko?
ʻOiai ke hana ʻia nei nā kalapona i hana ʻia ma kahi kūloko, hāʻawi ka kalapona i hoʻāla ʻia me ka pūpū niu i kahi ʻili micro-pore kiʻekiʻe aʻe a me ka paʻakikī mechanical kiʻekiʻe loa (≥99%). Hāʻawi ka AuCarb™ Coconut Carbon i ka hiki ke hoʻouka gula kiʻekiʻe aʻe (K-value) a me nā helu attrition haʻahaʻa loa i hoʻohālikelike ʻia me ke kalapona lanahu.
9. He aha ka manawa alakaʻi maʻamau no ka lawe ʻana i nā pahu kemika mai ke awa ʻo Durban i nā wahi eli?
Ke pae nā moku moana ma ke awa ʻo Durban, hiki i kā mākou mau kaʻina hana dute i ʻae mua ʻia ke hoʻouna ʻana i nā ipu i loko o 3 a 5 mau lā ʻoihana. ʻO ka hele ʻana ma ke alanui i Gauteng, Free State, a i ʻole Barberton e lawe i 24 a 48 mau hola hou aʻe, e hōʻoia ana i ka mālama ʻana i nā waihona i hiki ke wānana ʻia.
10. Pehea e hiki ai i nā mea hana hao mea kanu ʻApelika Hema ke noi aku i nā hāpana manuahi no ka hoʻāʻo ʻana i ka ʻōwili ʻōmole ma ka hale hana?
Hiki i nā Luna Hoʻokele Metallurgists a me nā Luna Hoʻokele Keʻena Hoʻokolohua ma ʻApelika Hema ke noi i nā Laʻana Hoʻāʻo Manuahi o AuCyan™, AuCarb™, a i ʻole AuLeach™ ma o kā mākou palapala hoʻopili pūnaewele. Hoʻouna pololei mākou i nā pahu laʻana i kāu keʻena hoʻokolohua no nā loiloi ʻōwili ʻōmole CIL a me ka adsorption kinetic.
