Ukufakwa kwentsimbi ye-lead-zinc kufuneka kuxhamlwe phambi kokuba isetyenziswe ngcono.Eyona ndlela ixhaphakileyo yokuxhamla kukuphaphazela.Kuba idada, imichiza edadayo ayinakwahlulwa ngokwendalo.Oku kulandelayo sintshayelelo kwii-reagents ezijikelezayo ezisetyenziswa kwi-lead-zinc ores:
1. Izilawuli ze-lead kunye ne-zinc flotation: Abalawuli banokwahlulwa babe yi-inhibitors, activators, medium pH regulators, slime dispersants, coagulants kunye ne-re-coagulants ngokwendima yabo kwinkqubo yokujikeleza.Abalawuli baquka iikhompawundi ezahlukeneyo ze-inorganic (ezifana neetyuwa, iziseko kunye neeasidi) kunye neekhompawundi eziphilayo.I-arhente efanayo ihlala idlala iindima ezahlukeneyo phantsi kweemeko ezahlukeneyo zokudada.
2. Abaqokeleli belothe kunye ne-zinc flotation.Abaqokeleli abasetyenziswa ngokuqhelekileyo baquka: i-xanthate kunye neyeza elimnyama.Iklasi ye-Xanthate ibandakanya i-xanthate, i-xanthate esters, njl.Inamandla okuqokelela e-galena kunye ne-chalcopyrite, kwaye umthamo wayo wokuqokelela i-pyrite ulinganisiwe.Ubuthathaka, ukukhetha okulungileyo, isantya sokudada ngokukhawuleza, ngaphantsi koncedo kune-xanthate, kwaye inomlinganiselo oqinileyo wokubamba amasuntswana arhabaxa e-sulfide ores.Xa isetyenziselwa ukwahlula i-ores ye-copper-lead-sulfur ratio, inokufumana ngcono kune-xanthate.Isiphumo esingcono sokuhlela.Iyeza elimnyama Iyeza elimnyama ngumqokeleli osebenzayo we-sulfide ores.Ikhono layo lokuqokelela libuthathaka kunelo xanthate.Imveliso ye-solubility ye-dihydrocarbyl dithiophosphate ye-ion yensimbi efanayo inkulu kune-xanthate ye-ion ehambelanayo.Iyeza elimnyama Ineempawu zogwebu.Umgubo osetyenziswa ngokuqhelekileyo kumashishini uquka: No.Phakathi kwazo, i-butylammonium powder emnyama (i-dibutyl ammonium dithiophosphate) ngumgubo omhlophe onokulula Inyibilika emanzini, ijika ibe mnyama emva kobuqhophololo, kwaye ineempawu ezithile zogwebu.Ilungele ukuphaphatheka kweentsimbi zesulfide ezifana nobhedu, ilothe, izinki, kunye nenickel.
Ukongeza, i-cyanide inokuthintela ngamandla i-sphalerite, kunye ne-zinc sulfate, i-thiosulfate, njl.
