Kakaretso ea kakaretso ea lead le Zinc liminerale

1. Moetsi oa Doinc Flotation

Babokelli ba sebetsang ba sebelisoang bakeng sa li-Zinc tse etellang pele ba kenyelletsa:

1. Xanthate. Mofuta ona oa moemeli o kenyelletsa Xanthate, Xanthate Ester, joalo-joalo

2. SLULFUR Netrojen, joalo ka Ethyl Sulfogha Netrogen, e na le bokhoni ba ho bokella matla ho feta Xanthate. E na le tokelo e matla ea ho bokella Galena le ho Chalcopyrite, empa bo fokola ka matla a ho bokella PYRITE, ho ikhetholla ho ntle, ho potlakile ho feta Xanthate. E na le karohano e matla ea pokello ea pokello ea korosa ea leoatle ea Ore. Ha e sebelisoa bakeng sa ho hlophisa likotlo tse ikhethang tsa koporo - sulur-sumpur li ka fumana litlamorao tse hlokofatsang ho feta Xanthate.

3.black moriana

Polao e Ntšo e na ea 'mokelli oa Sulfide oa Sulfide oa SULFID,' me bokhoni ba pokello ea eona bo fokolang ho feta ba Xanthate. Sehlahisoa sa sohydrocarbyl dithiophote of the tšepe e tšoanang ho feta tsa Xamanthate ea ion e lumellanang. Moriana o motšo o na le thepa e litšila.

Hangata ho sebelisoa matla a maputsoa indasteri a kenyelletsa: No. phofo e ntšo, Buylammoni Polder ea Black, Amine phofo e ntšo, 'me naphtheni e ntšo e ntšo. Har'a bona, Buylammonium White Ammonium Dithiophote) Ke phofo e tšoeu, e fetoha thepa e ntšo, e fetoha thepa e ntšo, 'me e na le thepa e ntšo, e fetoha thepa e ntšo, e na le thepa e ntšo,' me e na le thepa e ntšo, 'me e na le thepa e ntšo,' me e na le thepa e ntšo, 'me e na le thepa e ntšo,' me e na le thepa e ntšo, 'me e na le thepa e ntšo,' me e na le thepa e ntšo, 'me e na le thepa e ntšo. E loketse ho fofa lifu tsa sulfide joalo ka koporo, lead, zinc le nickel. . Ka boroko bo sa senyeheng ka mokhoa o fokolang, bokhoni ba pokello ea Pyrite le Pyrrhotite bo fokola, empa bokhoni ba pokello ea Galena bo matla.

2. Khoele ea Phahameng le Zinc Flotation

Ho latela karolo ea bona ts'ebetsong ea ho phaphamala, li-antransters li ka aroloa: Lihlokotsi, baetsi ba lihlotšoana, bo-alugers tsa bomunu, li-briments le matsala.

Basebetsi ba kenyelletsa metsoako e fapaneng ea inboric (joalo ka letsoai, metheo le acids) le metsoako ea mali. Moemeli e ts'oanang khafetsa o bapala likarolo tse fapaneng tlasa maemo a fapaneng a lipalesa.

Li-inhibitors:

1. Lime lime Ho thata ho khelosa ka metsing 'me ke Alkali ea matla. Boitšoaro ha bo eketsoa ho slurry ea flotation e tjena:

Cao + H2O = CA (OH) 2

Ca (Oh) 2 = Nahy + oh-

Kahy + = Ca2 ++ 0H-

Hangata kalama e sebelisoa hangata ho eketsa boleng ba PH ea ho thella le ho thibela liminerale tsa tšepe tsa tšepe. Ka Leseli la koporo, lead, le li-ores tsa Zyc, hangata li tsamaisana le tšepe (Pyrite, le Pyroarseenite le Pyroarseyrite). Bakeng sa ho ntlafatsa koporo, etella pele le liminerale tsa Zinc, hangata li-lime li kenyelitsoe ka liminerale tsa tšepe tsa sulfide.

2. Changnide (Nacn, KCN)

Cyannide ke inhitor e sebetsang nakong ea lead le zinc e hlophise. Canide ke boholo ba Cildium Cildium Cildimide le Wasim Cilnide, le Calcium cilnide le tsona li sebelisoa.

Cilnide ke letsoai le hlahisoang ke asiti e matla le e fokolang. Hoa bonesoa ka setulong ho hlahisa HCN le CN-

Kcn = k ++ cn-

Cn + h2o = hcn ++ oh-

E ka bonoa ho equation e ka holimo e lekantsoeng e lekantsoeng ea alkaline, khatello ea CN- E Etsisoa, e Molemong oa ho thibela. Haeba pH e theotsoe, hcn (acid ea hyd (hydrocic Ka hona, ha a sebelisa Cilnide, alkaline mofuta oa alkaline oa slurry o lokela ho bolokoa.

3.zinc sulfate

Phello e hloekileng ea Zinc Sulfate e tšoeu, e boreleli ka metsing, 'me ke mohloekisi oa shanyulete. Hangata ho na le phello ea li-albaline feela. Ha ph ea ph ea slurry, e se e totobatsoa haholoanyane ke phello ea eona ea li-shinitors. Zinc Sulfate e hlahisa karabelo e latelang ka metsing:

Znso4 = zn2 ++ so42-

Zn2 ++ 2h20 = ZN (OH) 2 + 2H!

ZN (OH) 2 ke komporo ea amithoteric ho qhibiliha ho acid ho theha letsoai.

Zn (Oh) 2 + h2s04 = ZNSO4 + 2H2O

Alkaline Dind, Hzno2- le zno22- li fumanoa. Khokahano ea bona ho liminerale e ntlafatsa hydrophilicity ea libaka tse liminerale.

Zn (Oh) 2 + Nahzno2 + h2O

Rona (Oh) 2 + 2Hzno2 + + +

Ha Sulfate e sebelisoa ke sebelisoa ke le mong, phello e thibelang e futsanehile. Hangata e sebelisoa hammoho le Cyanide, Sodium sulfide, sulfite kapa thilisulfate, sodium carbonate, jj.

Ts'ebeliso e kopaneng ea Zinc Sulfate le Cyan e ka ntlafatsa phello ea lits'oants'o. Karolelano ea nako e tloaelehileng ke hore: Cynanide: Zinc Sulfate = 1: 2-5. Ka nako ena, Cn- le zn2 + for kolao ea koluidal zn (cn) 2.
