Embonini yezimayini, ukumbiwa kahle kwegolide ezitsheni zensimbi kubaluleke kakhulu. Njengoba ukukhathazeka kwezemvelo kukhula, ukuthuthukiswa kanye nokusetshenziswa kwezindlela zokukhipha imvelo ezinobungane sekuyinto okugxilwe kuyo kakhulu. Lesi sihloko sethula imiphumela yokuhlolwa kwe-synergistic leaching ore yegolide yezinga eliphezulu kusetshenziswa i-ejenti yokucwilisa evumela imvelo futhi I-Sodium Cyanide.
I-Eco-friendly Gold Leaching Reagent
Sodium i-cyanide
Isingeniso
Imboni yezimayini zegolide sekuyisikhathi eside ithembele ezinqubweni zendabuko zokucwiliswa kwe-cyanide ukuze ikhiphe igolide ematsheni. Kodwa-ke, i-cyanide inobuthi obukhulu futhi ibeka ubungozi obubalulekile bemvelo nokuphepha. Ngakho-ke, kunesidingo esiphuthumayo sokuthola ezinye izindlela noma ukuthuthukisa ubuchwepheshe obunganciphisa ukusetshenziswa kwe-cyanide ngenkathi kugcinwa ukusebenza kahle okuphezulu kokukhipha. I-ejenti yokucwilisa igolide evumelana nemvelo esetshenziswe kulolu cwaningo ingenye indlela ethembisayo, futhi umphumela wayo wokusebenzisana i-sodium cyanide kwaphenywa ukuze kutholakale ukuthi kungenzeka yini ukusebenzisa le nhlanganisela ore wegolide wezinga eliphezulu.
Izinto Zokuhlola kanye Nezindlela
Izici ze-Ore
Insimbi esetshenziswe kulokhu kuhlola yayinezinga legolide elingu-12.24 g/t kanye nesigaba sesiliva esingu-131.91 g/t. Lawa mabanga aphakeme uma kuqhathaniswa ayenza ibe yikhandidethi elifanele lokuhlola ukusebenza kahle kwenqubo yokufundisa nge-synergistic leaching.
Izimo Zokuhlola
Ukuqina kokugaya: ~ 74 μm kubalwe u-95%. Lokhu kugaya kahle kubalulekile njengoba kwandisa indawo engaphezulu yezinhlayiya ze-ore, kube lula ukusabela kokucwiliswa.
Isilinganiso se-ejenti yokucwilisa igolide evumelana nemvelo: 2 kg/t. Inani elithile lanqunywa ngokuhlolwa kokuqala ukuze kuthuthukiswe umphumela wokuleaching.
Umthamo we-sodium cyanide: 1 kg/t. Ukunciphisa umthamo we-cyanide ngenkathi kugcinwa ukusebenza kahle kwe-leaching kungenye yezinhloso eziyinhloko zalolu cwaningo.
Umthamo we-Lime: 4 kg/t. I-lime yengezwa ukuze kulungiswe i-pH ye-pulp, ebalulekile ekuzinzeni nasekusebenzeni kahle kwenqubo yokucwilisa.
Ukugxila kwe-Pulp: 40%. Lokhu kugxila kunikeza indawo efanelekile yokuthi ama-reagents agelezayo asabele ngezinhlayiya ze-ore.
Isikhathi sokuvula: 24h. Kudingeka isikhathi esanele sokukhipha amanzi ukuze kuqinisekiswe ukuthi igolide nesiliva kukhishwa ngokugcwele.
Imiphumela yokuhlola
Ngaphansi kwezimo zokuhlola ezishiwo ngenhla, amazinga okukhishwa kwegolide nesiliva akalwa. Imiphumela ikhombise ukuthi izinga lokucwiliswa kwegolide lingagcinwa lizinzile liku-98.07%, kanti izinga lokucwiliswa kwesiliva lifinyelele ku-86.30%. Lawa mazinga aphezulu okukhipha amanzi akhombisa ukuthi indlela yokucolisa i-synergistic kusetshenziswa i-ejenti yokucwilisa igolide evumelana nemvelo kanye I-sodium cyanide iphumelela kakhulu kule nsimbi yegolide yezinga eliphezulu.
Ingxoxo
Amazinga aphezulu okukhipha amanzi atholwe kulokhu kuhlolwa angabalelwa esenzweni esihlanganisiwe se-ejenti yokucwilisa igolide evumelana nemvelo kanye ne-sodium cyanide. I-ejenti evumelana nemvelo ingase ithuthukise ukusebenza kabusha kwendawo ye-ore, ikwenze kube lula ukuthi i-cyanide iphendule ngegolide nesiliva. Ngesikhathi esifanayo, umthamo oncishisiwe we-sodium cyanide awusizi nje ukunciphisa izingozi zemvelo kodwa futhi wehlisa izindleko zokukhiqiza ngezinga elithile. Ukulungiswa kwe-pH nge-lime nakho kudlala indima enhle ekukhuthazeni ukusabela kwe-leaching.
Isiphetho
Lolu cwaningo lubonisa ukuba nokwenzeka kokusebenzisa indlela yokukhipha i-synergistic ne-ejenti yokucwilisa igolide evumelana nemvelo kanye ne-sodium cyanide yensimbi yegolide yezinga eliphezulu. Amazinga aphezulu okugezwa kwegolide nesiliva atholwe ngaphansi kwezimo ezithuthukisiwe abonisa amandla amakhulu okusetshenziswa kwezimboni. Le ndlela ayigcini nje ngokuthuthukisa ukusebenza kahle kokukhipha kodwa futhi yehlisa umthelela wemvelo ohambisana ne-cyanide yendabuko - izinqubo zokucwilisa kuphela. Ucwaningo olwengeziwe lungenziwa ukuze kuthuthukiswe amapharamitha enqubo ngokuqhubekayo futhi kwandiswe ububanzi bokufaka isicelo ezinhlotsheni ezihlukene zezinsimbi zegolide.
