Tataiso e Pharalletseng ea Li-reagents tsa Flotation ho Copper Ore Flotation

Li-reagents tsa flotation li bohlokoa ho arola liminerale tsa bohlokoa tsa koporo le majoe a litšila nakong ea ts'ebetso ea ho phaphamala. Sepheo se seholo sa ho phaphamala ha koporo ke ho hlahisa motsoako oa koporo o rekisoang. Ho fihlela sena, ho sebelisoa li-reagents tse fapaneng, hangata li aroloa ka mekhahlelo e mene e meholo: babokelli, bo-ntate, pH modifiers, le ba qhalanyang.

1. Babokelli ba Copper Flotation

Babokelli ba bapala karolo ea bohlokoa ho phaphameng ha koporo ka ho hokela bokaholimo ba liminerale tsa koporo, ho etsa hore e be hydrophobic. Sena se lumella liminerale tsa koporo hore li khomarele li-bubble tsa moea le ho nyolohela ka holim'a sele ea flotation. Babokelli ba tloaelehileng bakeng sa flotation ea koporo ba kenyelletsa xanthates le dithiophosphates (li-reagents tse ntšo).

• Li-Xanthate
  Li-xanthate tse kang ethyl xanthate le pentyl xanthate li sebelisoa haholo babokelli ba flotation ba koporo. Li khahlisa ka holim'a liminerale tsa koporo, li li etsa hydrophobic mme ka hona ho bonolo ho li hokela ho li-bubble tsa moea ka seleng ea flotation.

• Dithiophosphates (li-reagents tse ntšo)
  Dithiophosphate reagents tse kang sodium diisobutyl dithiophosphate (black sodium reagent) le ammonium diisobutyl dithiophosphate (black ammonium reagent) le tsona li sebelisoa hangata. Li sebetsa ka mokhoa o ts'oanang ka ho ntlafatsa hydrophobicity ea liminerale tsa koporo, ho thusa ho phalla hantle.

2. Frothers bakeng sa Copper Flotation

Li-Frothers li kenngoa liseleng tsa flotation ho hlahisa li-bubble tse tsitsitseng tse tsamaisang liminerale tsa koporo tsa hydrophobic holim'a sele, moo li ka tlosoang teng.

• Oli ea Pine
  Oli ea phaene ke e 'ngoe ea li-frothers tse sebelisoang haholo. E etsa lera le tsitsitseng la lehloa le tlisang liminerale tsa koporo holimo bakeng sa ho bokelloa.

• Methyl Isobutyl Carbinol (MIBC)
  MIBC ke mofuta o mong o tsebahalang, o tsejoang ka thepa ea eona e ntle ea ho thothomela le botsitso, e ntlafatsang ts'ebetso ea ho phaphamala.

• Polyether Frothers
  Metsoako ea polyether joalo ka polyethylene glycol le polypropylene glycol le tsona li sebelisoa ho phaphamala ha koporo. Li-frothers tsena li fana ka li-bubble tse tsitsitseng le ho tšehetsa ts'ebetso e ntle ea ho phaphamala.

3. Liphetoho tsa pH bakeng sa Copper Flotation

Li-modifiers tsa pH li laola maemo a lik'hemik'hale a flotation slurry ho hola ho hlaphoheloa koporo. Liphetoho tse tloaelehileng tsa pH li kenyelletsa lime, sodium hydroxide, le sulfuric acid.

• Lime le sodium hydroxide
  Lime le sodium hydroxide li sebelisoa ho fetola slurry pH, ho ntlafatsa ts'ebetso ea koporo ea koporo. Taolo e nepahetseng ya pH e bohlokwa bakeng sa ho kgetheha ha koporo ho tswa diminerale tse ding.

• Li-inhibitors le li-activators
  Li-inhibitors joalo ka Sodium cyanide le ferrous sulfate li sebelisetsoa ho thibela liminerale tse sa batleheng ho phaphamala, ho ntlafatsa khetho ea ho phaphamala ha koporo. Li-activators, tse kang koporo sulfate, li sebelisoa ho matlafatsa ho phalla ha liminerale tsa koporo sulfide.

4. Li-disperants bakeng sa Copper Flotation

Dispersants ntlafatsa kabo ea li-reagents le likaroloana tiileng ka flotation slurry, ho etsa bonnete ba ho kopana molemo pakeng tsa liminerale koporo le reagents flotation.

• polyacrylamides
  Polyacrylamide ke dispersant e sebelisoang ho pharaletseng e thusang ho thibela ho kopana ha likaroloana, ho netefatsa tšebelisano e ntle ea reagent le ho phaphamala ha koporo.

• Li-resin tsa epoxy
  Li-resin tsa epoxy li boetse li sebelisoa ka lebaka la thepa ea tsona e babatsehang ea ho qhalakanngoa le ho khomarela, ho ntlafatsa mokhoa oa ho phalla ka kakaretso.
