Masu tattara tattarawa da aka yi amfani da su don jagoran-zinc Ors sun haɗa da:
1. Xanthate. Wannan nau'in wakilin ya hada da xantal, xanthate etter, da sauransu.
2. Jeffur nitrogen, kamar ethyl sulfur Nitrogen, yana da ikon tattarawa girma fiye da xanthate. It has strong collection ability for galena and chalcopyrite, but weak ability to collect pyrite, good selectivity, fast flotation speed, and fewer uses than xanthate. Tana da karfin tarin tarin don m barbashi na sulfide ore. Lokacin da ake amfani da shi don warware takamaiman dutsen jan ƙarfe, zai iya samun mafi kyawun tasirin tasirin fiye da Xantatate.
3.Baliyya
Black foda mai yawan mai da inganci ne na sulfide m ores, da kuma tarin tarin sa ya fi na xanthate. Abu na narkewa na Dihydrocarbyl Dithoophate na wannan ion ion shine ya fi na Xantate na maniyyi. Magungunan baƙar fata yana da kayan kwalliya na foaming.
Powders da aka saba amfani da shi da baƙar fata a masana'antu sun haɗa da: A'a 4 Black foda, bakar fata baki, da kuma naphaith m foda. Daga gare su, bakar fata baki daya (dibutyl ammonium diteriophosphate) wani farin foda ne, sauƙaƙe da sauƙi a ruwa, kuma yana da ƙwanƙwasa kayan kwalliya. Ya dace da flotation na sulfide masara kamar jan ƙarfe, kai, zinc, da nickel. . A cikin rauni alkaline slurry, iyawar tarin pyrrite da pyrrhotite yana da rauni, amma iyawar tarin Galena mai ƙarfi ne.

Dangane da matsayinsu a cikin tsarin flotation, adjusters, masu fafuti, matsakaici, tsaka-tsaki da kuma sake coagulants.
Adjusters sun haɗa da mahadi iri-iri daban-daban (kamar salts, sansani da acid) da kuma mahadi na kwayoyin. Wannan wakili iri ɗaya yakan taka rawa daban-daban a karkashin yanayin flot daban.
Inhihiitors:
1. Lemun tsami lemun tsami (CAO) yana da karfin ruwa mai ƙarfi da kuma amsawa da ruwa don samar da lemun tsami ca (oh) 2. Zai yi wuya a watsa cikin ruwa kuma mai ƙarfi alkali ne. Halin da aka kara a cikin Flotation Slurry shine kamar haka:
Cao + h2o = ca (oh) 2
Ca (oh) 2 = caoh ++ oh-
Caoh + = Ca2 + + 0H-
Ana amfani da lemun tsami sau da yawa don haɓaka ƙimar pH na slurry da kuma hana ma'adinan sulfide ma'adanai. A sulfde jan karfe, jagoranta, da zinc ess, sau da yawa ana tare da su na baƙin ƙarfe sulfide (Marcasite, da pyrrohotenite). Don kyakkyawan jan ƙarfe na flotate, jagoranci, da zinc ma'adinai, lemun tsami ana ƙara ƙara a cikin ma'adanar sulfide na baƙin ƙarfe.
2. Cyanide (Nacn, KCN)
Cyeande wani mai amfani ne mai amfani yayin jagorancin da zinc yana. Cyeande galibi sodium cyanide da potassium cyande, kuma ana amfani da Cyanan Cyanide.
Cyanide gishiri ne da aka samu ta hanyar karfi tushe da rauni acid. An hydrolyzed a cikin slurry don samar da HCN da CN-
KCN = k ++ cn-
CN + H2O = HCN ++ Oh-
Ana iya ganin hakan daga daidaitaccen daidaituwa wanda ke cikin alkaline slurry, maida hankali ga Cn- yana ƙaruwa, wanda yake da amfani ga hanawa. Idan an saukar da PH, HCN (Acidan (hydrocyanic acid) an kafa shi da kuma infibitory tasirin sakamako. Saboda haka, lokacin amfani da cyande, yanayin alkaline yanayin dole ne a kiyaye.
3.Zinc sulfate
Mafi tsarkakan samfur na zinc crystal, a sauƙaƙe sanyaya cikin ruwa, kuma mai sa ido ne na spatherite. Yawancin lokaci yana da tasirin inhibitory kawai a cikin alkaline slurry. A mafi girma da pH na slurry, mafi bayyananne bayyanannen tasirinsa. Zinc sulfate yana samar da abin da ke gaba cikin ruwa:
Znso4 = ZN2 ++ S42-
ZN2 ++ 2H2 = ZN (OH) 2 + 2h +
ZN (OH) 2 shine fili mai sihiri wanda ke narkewa a cikin acid don samar da gishiri.
Zn (oh) 2 + h2s04 = zno4 + 2h2o
A cikin alkaline matsakaici, hzno2- da zno22- an samu. ADDUPLAPLAPLAGE ga ma'adinai yana musayar hydrofity na ma'adinai.
ZN (OH) 2 + Nahzno2 + H2O
Zn (oh) 2 + 2 2nooh = na2zno2 + 2h2o
Lokacin da ake amfani da sulfate zincate shi kadai, illa mai hana shi ne talauci. Galibi ana amfani dashi a hade tare da cyanide, sodium sulfide, sulfite ko thiosulffate, sodium carbonate, da sauransu.
Hada amfani da zinc sulfate da Cyanide na iya haɓaka tasirin inabi a kan SPHALATA. Rayayyun da aka saba amfani da shi shine: Cyanide: zinc sulfate = 1: 2-5. A wannan lokacin, CN- da Zn2 + form Colloidal Zn (CN) 2 hazo.
