Ukufakwa kwe-lead-zinc ore kufanele kuzuzwe ngaphambi kokuthi isetshenziswe kangcono.Indlela yokuhlomula esetshenziswa kakhulu i-flotation.Njengoba i-flotation, amakhemikhali e-flotation awahlukaniseki ngokwemvelo.Okulandelayo yisingeniso kuma-reagents e-flotation asetshenziswa ku-lead-zinc ores:
1. Izilawuli ze-lead ne-zinc flotation: Izilawuli zingahlukaniswa zibe ama-inhibitors, ama-activator, abalawuli be-pH ephakathi, ama-slime dispersants, ama-coagulants kanye nama-coagulants kabusha ngokwendima yawo enqubweni yokuntanta.Izilawuli zibandakanya izinhlanganisela Ezihlukahlukene ze-inorganic (ezifana nosawoti, izisekelo nama-asidi) nezinhlanganisela eziphilayo.I-ejenti efanayo ivame ukudlala izindima ezihlukene ngaphansi kwezimo ezihlukene zokuntanta.
2. Abaqoqi be-flotation be-lead nezinc.Abaqoqi abavame ukusetshenziswa bahlanganisa: i-xanthate nomuthi omnyama.Isigaba se-Xanthate sihlanganisa i-xanthate, i-xanthate esters, njll. Isigaba se-sulphur nitrogen, njenge-ethyl sulfide, sinamandla okuqoqa anamandla kune-xanthate.Inomthamo oqinile wokuqoqa we-galena ne-chalcopyrite, futhi umthamo wayo wokuqoqwa kwe-pyrite uyalinganiswa.Ukukhetha okubuthakathaka, okuhle, isivinini sokuntanta okusheshayo, usizo oluncane kune-xanthate, futhi kunesilinganiso esinamandla sokuthwebula sezinhlayiya ezimahhadla ze-sulfide ores.Uma isetshenziswa ekuhlukaniseni i-copper-lead-sulfur ratio ores, ingathola kangcono kune-xanthate.Umphumela ongcono wokuhlunga.Umuthi omnyama Umuthi omnyama ungumqoqi osebenzayo we-sulfide ores.Ikhono layo lokuqoqa libuthakathaka kunalelo le-xanthate.Umkhiqizo wokuncibilika we-dihydrocarbyl dithiophosphate we-ion yensimbi efanayo mkhulu kunalowo we-xanthate ye-ion ehambisanayo.Umuthi omnyama Unamagwebu.Izimpushana ezimnyama ezivame ukusetshenziswa embonini zihlanganisa: No. 25 impushana emnyama, impushana emnyama ye-butylammonium, i-amine powder emnyama, kanye nempushana emnyama ye-naphthenic.Phakathi kwazo, i-butylammonium powder emnyama (i-dibutyl ammonium dithiophosphate) iyimpushana emhlophe etholakala kalula Incibilika emanzini, ibe mnyama ngemva kokudakwa, futhi inezici ezithile zokugwedla.Ilungele ukuntanta kwezinsimbi ze-sulfide njengethusi, umthofu, i-zinc, ne-nickel.
Ngaphezu kwalokho, i-cyanide ingavimbela ngokuqinile i-sphalerite, futhi i-zinc sulfate, i-thiosulfate, njll ingavimbela ukugeleza kwe-sphalerite.
