Ubuchwepheshe bezinzuzo ze-cyanide ore

I-Clanidation ingenye yezindlela eziphambili zokuzuzisa izimayini zegolide, futhi ingahlukaniswa ngezinhlobo ezimbili: i-cranidation evusa ama-cranidation kanye ne-clecolation cranidation. Kule nqubo, inqubo yokuxuba yegolide ye-Cyanide Gold Extraction ikakhulukazi ifaka inqubo yokubuyiselwa kweChanide-Zinc Imishini esetshenziswa kakhulu yegolide ehlukanisayo isetshenziswa incnic powder yokubuyiselwa kwe-zinc, ukugqugquzela ithangi elivuselelayo, ukusetshenziswa okuphansi kwe-electrorly system.

1 Ukusungulwa kwamanje kuhloswe ngawo ikakhulukazi emishini yokuthola usizo yegolide equkethe okuphezulu kwesiliva ku-Ore yegolide. Ngemuva kokuhlanza uketshezi oluyigugu futhi ususe umoya-mpilo, insiza yokubuyiselwa kwe-zinc powder iyengezwa ukuthola udaka lwegolide. Lapho i-zinc powder (silika) isetshenziselwa ukufaka esikhundleni sezulu futhi ibuyise igolide, le ndlela ebizwa nge-Cyanide-Zinc Replatsement (CCD ne-CCF) ingasetshenziswa ekusebenzeni kokukhiqiza, noma ukushintshwa kwe-zinc powder kungasetshenziselwa ukwelapha izixazululo ezibizayo (izixazululo zokuvuselela ). Ngokuvamile, ngaphezu kwezimayini zegolide ezinokuqukethwe okuphezulu kwesiliva, amadivaysi okubuyiselwa kwe-zinc powder nawo angasetshenziswa ukucubungula ukugxila kwegolide okudinga ukuthuthukisa ibanga labo.

2. I-Double Eaching eshukumisayo evusa ithangi Ithangi elishukumisayo le-Impeller Leashing Tank liyinqubo esetshenziswa kakhulu yokusebenza kwamaminerali kwinqubo ye-Carbon Slurry Gold Expression yegolide (indlela ye-CIP kanye ne-CIL). Ngaphansi kwesenzo sokuhudula nokuvusa okushukumisayo kwe-impleller ephindwe kabili, ukugeleza kwe-slurry phansi kusuka enkabeni, kudalule ngamapuleti aphoqelekile azungezile, kufakwe umoya ekugcineni komgodi, kuxubana ne-slurry futhi kujikeleze kuya phezulu. Lesi sixazululo silungele izinhlelo zokusebenza ezinamandla amancane adonsela phansi, ukubonakala okuphansi kanye nezinga elisheshayo lemvula. , lapho usayizi wezinhlayiyana nge-ore ungaphezulu -200 mesh kanye nokuhlushwa kwezixazululo zegolide kungaphansi kwama-45%, kungakhiwa umngcele omisiwe womfaniswano. Ukumuncwa kanye neminye imisebenzi yokuxuba. Enqubweni ye-CIP yediphozithi yegolide, ukuqondiswa kwe-leaching kanye ne-adsorption imisebenzi ezimele. Ekusebenzeni kokutholwa, inqubo yokugqunywa yi-Leaching iqediwe. Ubukhulu, ubungako, kanye nezimo zokusebenza kwamathangi e-adsorption kunqunywa ngamapharamitha we-adsorption. Inqubo ye-CIL yediphozi yegolide ifaka phakathi kanye nokusebenza kwe-adsorption. Njengoba ukusebenza kwe-leaching kuthatha isikhathi eside kunokusebenza kwe-adsorption, ubukhulu bethangi elivuselelayo lokuvuselela linqunywa ngamapharamitha wokuvutha ukunquma inani le-aeration ne-dosing. Ngoba izinga lokufakwa ahlobene nomsebenzi wokuhlushwa igolide elicijile, amazinga we-1-2 wokugcotshwa kwangaphambili avame ukwenziwa ngaphambi kokubhapathizwa kwemigqa ukukhulisa ukugcwala kwegolide elichithiwe ethangini le-adsorption futhi kwandise isikhathi sokufundisa.

3. Ukusetshenziswa okuphansi okusheshayo kwe-electrolysis system. Uhlelo oluphansi lokusetshenziswa kwama-elekrolorlysis aphansi lubekwe imishini yokugqoka yegolide yegolide evuthayo kanye nama-electrolytes carbon alayishwe i-carbon ukukhiqiza udaka oluphezulu ngaphansi kokushisa okuphezulu kanye nengcindezi ephezulu. I-carbon slurry yegolide elayishwe ngegolide ithunyelwa esikrinini sokuhlukaniswa kwekhabhoni (imvamisa isikrini sokudlidliza) ngephampu yekhabhoni noma nge-air liveter. Ingaphezulu lesikrini ligezwa ngamanzi ahlanzekile ukuhlukanisa ikhabhoni kusuka ku-slurry. Ikhabhoni elayishwe igolide ingena ithangi lokugcina ikhabhoni, ama-slurry namanzi acwebezelayo. Faka isigaba sokuqala sethangi le-adsorption. Usebenzisa uhlelo lwe-electrolylis oluphansi futhi olusheshayo lwe-elektrolorlingathi wokufaka ama-anions angangena esikhundleni se-AU (CN) 2- nge-AU (CN) 2-, futhi uketshezi oluyigugu olutholwe nge-carbon egcwele igolide kungalulama ngegolide eliqinile ngendlela yoku-ionization. Ukusetshenziswa kwamandla okuphansi kwe-electrorlyliss advocate aflectrorpring kunesilinganiso sokukhuhla ngaphezu kwama-98% ngaphansi kwezinga lokushisa eliphakeme (150 ° C) kanye nokucindezela kwamandla (4 ~ 1 ~ 1 ~ 1 ~ 1 ~ 1 ~ 1 ~ 1 ~ 1 ~ 1 uhlelo. Inhlanganisela engeyona enobuthi futhi ethobekile iqukethe i-carbon activator, engavuselela i-carbon. I-carbon ethambile ayidingi ukushintshwa kabusha yindlela yomlilo, egcina izindleko zokuvuselelwa kwekhabhoni. I-slurry yegolide ingelokungaphezulu okuphezulu, ayidingi i-electrolysis yokubuyela emuva, futhi kulula ukuyikhipha. Ngasikhathi sinye, uhlelo oluphansi lokusetshenziswa kwe-electrolysis ngokushesha futhi lusebenzisa izindlela ezintathu zokuphepha, okungukuthi ubuhlakani bohlelo uqobo, umfutho othomathikhi okhawulelwe kanye ne-valve yokuphepha komshuwalense.
