Jagora da zinc suna da manyan kayan abinci na asali don ci gaban tattalin arzikin zamantakewa na zamani. Tare da cigaban tattalin arziki, bukatar jagoranci da zinc na faruwa ga karuwa, da ingantaccen sake dawowar hadaddun da wuya-zuwa-zabi jagoranci da zinc ma'adinai ya kara da gaggawa. A cikin wannan mahallin, sabbin ayyukan sarrafa ma'adinai, musamman masu karuwa tare da karfi tarin aiki da masu aiki, da kuma ingantaccen muhimmiyar rarrabuwa da ingantaccen rabuwa da karfin gwiwa zinc ers. Mai zuwa zai ba ku cikakkiyar fahimtar nau'ikan reagents amfani da shi a cikin jagoran-zinc ere flotation.
Jagorar da Zinc
xanthate
Irin waɗannan wakilai sun haɗa da Xanthate, xanthate Esters, da sauransu.
Sulfur da nitrogen
Misali, Ethyl sulfid yana da ikon tattarawa 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. Yana da karfin tattara iko ga sassa-karfi na sulfide esres, kuma lokacin da aka yi amfani da su don warware takamaiman Orer-sulfur, zai iya cimma nasarar takamaiman sakamako na ja-gora, yana iya cimma kyakkyawan sakamako na gaba da Xanthate.
Magani baƙar fata
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.
Babban mai aiwatar da Fasaha da Zinc
Adjusters za a iya raba shi cikin hana, masu fafutuka, Media PH Adjusters, Slime watsawa, coagusants da masu balaguronsu bisa ga aikin da suka taka a cikin tsarin flotation. 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.
CYAN (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. Yana da hydrolyzes a cikin slurry don samar da HCN da CNˉ
KCN = K⁺ + CNˉ CN + H₂o = HCN⁺ + Oh
Daga daidaitawar daidaitawa, ana iya ganin hakan a cikin alkaline pulp, maida hankali na cnˉ yana ƙaruwa, wanda yake da amfani ga hana shi. 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. Cyanan shine wakili mai guba, kuma bincike kan cyanide-free-ƙasa da cyanide-ƙasa da ke gudana shekaru da yawa.
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:
Zno₄ = zn²⁺ + so₄
Zn²⁺ 2h
Zn (oh) ₂ + H₂so₄ = zno₄ + 2h₂o
A alkaline matsakaic, hzno₂ˉ da zno₂²ˉ an samu. ADDUPLAPLAPLAGE ga ma'adinai yana musayar hydrofity na ma'adinai.
Zn (Oh) ₂ + nah = Nahzno₂ + H₂o
ZN (Oh) ₂ + 2 2Naoh = na₂zno₂ + 2h₂o
Lokacin da ake amfani da sulfate zincate shi kadai, illa mai hana shi ne talauci. Ana amfani da shi a hade tare da cyanide, sodium sulfide, sodium carbleate sakamako a kan SPHERIDE zai iya inganta tasirin inabi. Rayayyun da aka saba amfani da shi shine: Cyanide: zinc sulfate = 1: 2-5. A wannan lokacin, CNEL da ZN²⁺ form Colloidal Zn (CN) ₂ hazo.
