Tšebeliso ea tšepe ea lead-zinc e tlameha ho ruisa molemo pele e ka sebelisoa hamolemo.Mokhoa o sebelisoang haholo oa ho thusa ke flotation.Kaha e phaphamala, lik'hemik'hale tsa flotation ka tlhaho ha li arohane.Se latelang ke selelekela sa li-reagents tsa flotation tse sebelisoang ho li-lead-zinc ores:
1. Li-lead le li-zinc flotation regulators: Li-regulators li ka aroloa ka li-inhibitors, activators, li-regulator tse mahareng tsa pH, li-slime dispersants, li-coagulants le li-coagulants hape ho ea ka karolo ea tsona ts'ebetsong ea ho phalla.Li-regulators li kenyelletsa Metsoako e fapaneng ea tlhaho (joalo ka matsoai, metheo le li-acid) le metsoako ea tlhaho.Hangata moemeli o tšoanang o bapala likarolo tse fapaneng tlas'a maemo a fapaneng a ho phaphamala.
2. Babokelli ba flotation ea lead le zinki.Babokelli ba sebelisoang ka tloaelo ba kenyelletsa: xanthate le meriana e ntšo.Sehlopha sa xanthate se kenyelletsa xanthate, xanthate esters, joalo-joalo Sehlopha sa naetrojene ea Sulfur, joalo ka ethyl sulfide, e na le matla a ho bokella ho feta xanthate.E na le matla a ho bokella a galena le chalcopyrite, 'me bokhoni ba eona ba pokello ea pyrite bo lekantsoe.Khetho e fokolang, e ntle, lebelo la ho phaphamala ka potlako, ha e na thuso ho feta xanthate, 'me e na le tekanyo e matla ea ho ts'oara likaroloana tse mahoashe tsa sulfide ores.Ha e sebelisoa ho arola li-ores tsa koporo-lead-sulfur ratio, e ka fumana molemo ho feta xanthate.Phello e ntle ea ho hlopha.Meriana e ntšo Meriana e ntšo ke mokelli ea atlehang oa sulfide ores.Bokhoni ba eona ba pokello bo fokola ho feta ba xanthate.Sehlahisoa sa solubility sa dihydrocarbyl dithiophosphate ea ion ea tšepe e tšoanang e kholo ho feta ea xanthate ea ion e lumellanang.Meriana e ntšo E na le thepa ea ho phophoma.Liphoofolo tse ntšo tse sebelisoang ka tloaelo indastering li kenyelletsa: No. 25 phofo e ntšo, phofo e ntšo ea butylammonium, phofo e ntšo ea amine, le phofo e ntšo ea naphthenic.Har'a tsona, phofo e ntšo ea butylammonium (dibutyl ammonium dithiophosphate) ke phofo e tšoeu e bonolo E qhibiliha ka metsing, e fetoha e ntšo ka mor'a ho senyeha, 'me e na le lintho tse itseng tse phophomang.E loketse ho phaphamala ha ores ea sulfide joalo ka koporo, lead, zinki le nickel.
Ho phaella moo, cyanide e ka thibela ka matla sphalerite, 'me zinc sulfate, thiosulfate, joalo-joalo e ka thibela ho phalla ha sphalerite.
