Ma reagents oyandama mu lead-zinc ore flotation process

Kugwiritsidwa ntchito kwa lead-zinc ore kuyenera kupindula musanagwiritsidwe ntchito bwino.Njira yomwe imagwiritsidwa ntchito kwambiri ndi flotation.Popeza imayandama, mankhwala oyandama mwachilengedwe sangasiyane.Zotsatirazi ndikuyambitsa kwa ma reagents oyandama omwe amagwiritsidwa ntchito mu lead-zinc ores:
1. Owongolera ndi zinc flotation regulators: Owongolera amatha kugawidwa kukhala zoletsa, ma activator, owongolera pH apakati, ma dispersants a matope, ma coagulants ndi ma coagulants okonzanso malinga ndi gawo lawo pakuyandama.Zowongolera zimaphatikizanso zinthu zosiyanasiyana zopanga zinthu (monga mchere, zoyambira ndi zidulo) ndi ma organic compounds.Wothandizira yemweyo nthawi zambiri amasewera maudindo osiyanasiyana pamikhalidwe yoyandama.
2. Osonkhanitsa zoyandama za lead ndi zinki.Osonkhanitsa omwe amagwiritsidwa ntchito kawirikawiri ndi awa: xanthate ndi mankhwala akuda.Kalasi ya Xanthate imaphatikizapo xanthate, xanthate esters, etc. Sulfur nitrogen class, monga ethyl sulfide, ali ndi mphamvu yosonkhanitsa mphamvu kuposa xanthate.Ili ndi mphamvu yosonkhanitsa ya galena ndi chalcopyrite, ndipo mphamvu yake yosonkhanitsa ma pyrite imayesedwa.Zofooka, kusankha bwino, kuthamanga kwachangu koyandama, kopanda phindu kuposa xanthate, ndipo kumakhala ndi chiwopsezo cholimba cha tinthu tambiri ta sulfide ores.Akagwiritsidwa ntchito polekanitsa ma ore a copper-lead-sulfur ratio, amatha kupeza bwino kuposa xanthate.Bwino kusanja zotsatira.Mankhwala akuda Mankhwala akuda ndiwotolera bwino miyala ya sulfide.Kukhoza kwake kusonkhanitsa ndi kofooka kuposa kwa xanthate.The solubility mankhwala a dihydrocarbyl dithiophosphate wa zitsulo ion ion ndi yaikulu kuposa xanthate ya ion yogwirizana.Mankhwala akuda Ali ndi zinthu zotulutsa thovu.Mafuta akuda omwe amagwiritsidwa ntchito kawirikawiri m'makampani ndi awa: No. 25 ufa wakuda, ufa wakuda wa butylammonium, ufa wakuda wa amine, ndi ufa wakuda wa naphthenic.Pakati pawo, ufa wakuda wa butylammonium (dibutyl ammonium dithiophosphate) ndi ufa woyera womwe umasungunuka mosavuta, umasungunuka m'madzi, umasanduka wakuda pambuyo pa deliquescence, ndipo uli ndi zinthu zina zotulutsa thovu.Ndiwoyenera kuyandama kwa miyala ya sulfide monga mkuwa, lead, zinki, ndi faifi tambala.
Komanso, cyanide akhoza kwambiri ziletsa sphalerite, ndi nthaka sulphate, thiosulfate, etc. akhoza ziletsa kuyandama kwa sphalerite.
