Kuiswa kwe lead-zinc ore kunofanirwa kubatsirwa kusati kwagona kushandiswa zvirinani.Iyo inowanzoshandiswa beneficiation nzira ndeye flotation.Sezvo iri flotation, flotation makemikoro haachaparadzanisiki.Izvi zvinotevera sumo kune flotation reagents anoshandiswa mu lead-zinc ores:
1. Mutungamiri uye zinc flotation regulators: Vagadziri vanogona kukamurwa kuva inhibitors, activators, medium pH regulators, slime dispersants, coagulants uye re-coagulants maererano nebasa ravo mukugadzirisa flotation.Maregulator anosanganisira Akasiyana-siyana inorganic komisheni (semunyu, mabhesi uye maasidhi) uye organic komisheni.Mumiririri mumwechete anowanzo tamba mabasa akasiyana pasi pemamiriro akasiyana eflotation.
2. Mutungamiri uye zinc flotation vateresi.Inowanzo shandiswa vaunganidzi vanosanganisira: xanthate uye mutema mushonga.Xanthate kirasi inosanganisira xanthate, xanthate esters, etc. Sulfur nitrogen class, yakadai se ethyl sulfide, ine simba rakasimba rekuunganidza kupfuura xanthate.Iine simba rekuunganidza rakasimba re galena uye chalcopyrite, uye simba rayo rekuunganidza pyrite rinogadziriswa.Husina kusimba, kusarudza kwakanaka, kukurumidza kubhururuka kumhanya, kushoma kubatsira pane xanthate, uye ine yakasimba yekubata reshiyo yeakaomesesa zvimedu zvesulfide ores.Kana yakashandiswa mukuparadzaniswa kwemhangura-lead-sarufa ratio ores, inogona kuwana zvirinani pane xanthate.Zvirinani kurongedza maitiro.Mushonga wakasviba Mushonga mutema muunganidzi unobudirira we sulfide ores.Kukwanisa kwayo kuunganidza kwakaderera pane iyo ye xanthate.Iyo solubility chigadzirwa che dihydrocarbyl dithiophosphate yeiyo simbi ion yakakura kupfuura iyo xanthate yeion inowirirana.Mushonga mutema Une furo zvinhu.Hupfu nhema dzinowanzo shandiswa mumaindasitiri dzinosanganisira: No.Pakati pazvo, butylammonium poda yakasviba (dibutyl ammonium dithiophosphate) ipfu chena iri nyore Inonyungudika mumvura, inoshanduka kuva dema mushure mekushomeka, uye ine zvimwe zvinopupuma.Inokodzera kutenderera kwe sulfide ores semhangura, lead, zinc, uye nickel.
Mukuwedzera, cyanide inogona kudzivisa zvakasimba sphalerite, uye zinc sulfate, thiosulfate, nezvimwewo inogona kudzivisa kutenderera kwe sphalerite.
