Phallo ea liminerale ke mokhoa o sebelisoang haholo indastering ea merafo ho arola liminerale tsa bohlokoa ho liminerale tsa gangue. E itšetlehile ka ho se tšoane ha thepa ea 'mele le ea lik'hemik'hale ea bokaholimo ba liminerale. Sodium hexametaphosphate, ka sebopeho sa eona se ikhethang sa lik'hemik'hale le thepa, e fumane ts'ebeliso ea bohlokoa ho Phallo ea liminerale ditsamaiso. Sengoliloeng sena se shebisisa likarolo tse fapaneng tsa ts'ebeliso ea eona ho flotation ea liminerale.

Thepa ea sodium Hexametaphosphate

Sodium hexametaphosphate ke motsoako oa inorganic polymer. E bonahala e le kristale e bonaletsang e se nang 'mala kapa phofo e tšoeu. E qhibiliha haholo metsing, 'me tharollo ea eona ea metsi ke alkaline. Moeeng, e na le tekanyo e itseng ea hygroscopicity. Lintho tsena tsa 'mele le tsa lik'hemik'hale li rala motheo oa ts'ebetso ea eona ho flotation ea liminerale.

Likarolo ho Flotation ea Liminerale

Ho sithabela maikutlo

1. Thibelo ea Liminerale tsa Silicate le Carbonate

• Sodium hexametaphosphate e sebetsa hantle ho thibela liminerale tsa quartz le silicate. Ha ho phaphamala ha ores, joalo ka tse nang le feldspar le mica, e ka khahla holim'a liminerale tsena tsa silicate. Ka mohlala, ha ho phaphamala ha ores ea zirconium, ho ka fokotsa ho phaphamala ha feldspar e amanang le liminerale tse ling tsa silicate gangue ka ho bapatsa holim'a tsona.

• E boetse e bontša litlamorao tse thibelang k'habonediminerale tse kang calcite le lejoe la mokoetla. Ho phaphamala ha diminerale tsa phosphate moo calcite e leng minerale e tloaelehileng ya gangue, sodium hexametaphosphate e ka sebetsana le li-ion tsa calcium sebakeng sa calcite. E etsa metsoako e tsitsitseng e eketsang hydrophilicity ea sebaka sa calcite, e leng se etsang hore ho se ke ha e-ba bonolo hore se khomaretsoe ke 'mokelli, kahoo se finyella morero oa ho thibela.

2.Thibelo Mechanism

• E 'ngoe ea mekhoa e ka sehloohong ea ho thibela e amana le karabelo ea eona le li-ion tsa tšepe holim'a liminerale. Ha ho tluoa tabeng ea liminerale tse nang le li-ion tsa tšepe tse ngata, sodium hexametaphosphate e ka etsa metsoako e tsitsitseng ka li-ion tsena tsa tšepe. Ho flotation ea nickel ore, e sebetsana le li-ion tse khethehileng holim'a serpentine, e thibelang ho fofa ha noha.

• Ho phaella moo, ka tharollo ea metsi, sodium hexametaphosphate e ka ionize. E ka sebetsana le li-ion tsa calcium sebakeng sa diminerale le mohato oa mokelikeli. Karohanong ea calcite le cassiterite, motsoako o entsoeng holim'a calcite ha o ame feela calcite empa hape o ka 'na oa ba le adsorb holim'a cassiterite, ho fokotsa khetho ea ho thibela le ho fokotsa ho ba le mokelli holim'a liminerale.

Ea qhalaneng

1.Ho hasana ha Mineral Pulp

• Lits'ebetsong tsa ho phaphamala, haholo-holo bakeng sa ores tse ling tse nang le liminerale tse entsoeng hantle kapa tse nang le seretse se phahameng, ho hasana ha makhasi a liminerale ho bohlokoa. Sodium hexametaphosphate e ka bapala karolo ea bohlokoa joalo ka dispersant. Ka mohlala, ka flotation ea nickel - pyrite ores amanang le serpentine, phaella ka ho re palo e loketseng ea sodium hexametaphosphate ka qhalakanya makhasi a flotation. Sena ke hobane e fokotsa ho koaheloa ha noha holim'a nickel - pyrite, e leng molemo ho pholiso ea flotation ea nickel - pyrite.

2.Mokhoa oa Phatlalatso

• Sodium hexametaphosphate e ka theola matla a holimo a liminerale. Ka lebaka leo, matla a repulsive electrostatic pakeng tsa likaroloana tsa diminerale ea eketseha. Sebopeho sa eona sa limolek'hule, motsoako oa polymer o nang le bolelele ba ketane ea bonyane li-unit tsa 20 - 100, ha e bapaloa holim'a liminerale, e ka boela ea eketsa phello ea tšitiso ea steric pakeng tsa likaroloana. Ho phaphamala ha ores ea phosphate e entsoeng hantle, phello ena ea ho hasana e ka thibela ho bokellana ha phosphate le liminerale tsa gangue, ho ntlafatsa katleho ea karohano.

Kopo ho Fapaneng Mineral Flotation

Phosphate Ore Flotation

1.Kgetho karohano

• Ho flotation ea phosphate ore, sodium hexametaphosphate hangata e sebelisoa ho arola liminerale tsa phosphate ho liminerale tsa gangue. Phosphate ores hangata e amahanngoa le liminerale tse fapaneng tsa gangue tse kang calcite, dolomite le silicate minerals. Sodium hexametaphosphate e ka thibela ka mokhoa o ikhethileng liminerale tsena tsa gangue. Ts'ebetsong ea ho phaphamala ka morao ea ore ea phosphate, ho eketsa palo e nyane ea sodium hexametaphosphate ho ka eketsa ka katleho boemo le ho hlaphoheloa ha phosphate concentrate. E ka sebetsana le liminerale tse seng tsa phosphate ntle le ho sebetsana le liminerale tsa phosphate, kahoo e ntlafatsa khetho ea flotation ea phosphate mineral.

2.Phello ho Botsitso ba Foam

• E boetse e na le tšusumetso ho botsitso ba foam ho flotation ea phosphate ore. Foam e ts'ebetsong ea ho phaphamala e bapala karolo ea ho bokella liminerale tsa phosphate. Sodium hexametaphosphate e ka matlafatsa botsitso ba foam. E ka hlahisa palo e kholo ea foams e tsitsitseng, e thusang ho ntlafatsa phello ea pokello ea liminerale tsa phosphate. Liminerale tsa phosphate li ka tsamaisoa hantle ke foam e tsitsitseng ho ea holimo, ka hona ho ntlafatsa ts'ebetso ea flotation le maemo.

Non - Ferrous Metal Ore Flotation

1.Nickel Ore Flotation

• Joalokaha ho boletsoe pejana, ho flotation ea nickel ore, sodium hexametaphosphate e sebelisoa haholo-holo ho thibela noha. Serpentine ke diminerale e tloaelehileng ea gangue ores ea nickel, 'me boteng ba eona bo ka ama ho phaphamala ha liminerale tse nang le nickel. Ka ho eketsa sodium hexametaphosphate, e ka itšoara ka li-ion tsa tšepe holim'a metsi a noha, e fokotsa ho phaphamala ha eona le ho ntlafatsa karohano ea nickel e nang le liminerale tse tsoang ho noha. Sena se molemo bakeng sa ho ntlafatsa boemo le ho hlaphoheloa ha li-concentrate tsa nickel.

2.Koporo le Loto - Zinc Ore Flotation

• Ho flotation ya koporo le loto - zinc ore, ha ho na le calcium e amanang - e nang le diminerale tsa gangue tse kang calcite le dolomite, sodium hexametaphosphate e ka sebediswa ho thibela diminerale tsena tsa gangue. Ho tse ling tse rarahaneng koporo - lead - zinki ores, ho lokisa palo ea sodium hexametaphosphate ka ka katleho laola floatability ea liminerale gangue, ho ntlafatsa selectivity ea flotation le boleng ba koporo, loto, 'me zinki concentrates.

Lintlha tse Amang Phello ea Kopo

Tekanyo

1.Optimal Dosage Boikemisetso

• Tekanyo ea sodium hexametaphosphate e na le tšusumetso e kholo ts'ebetsong ea eona ho flotation ea liminerale. Tekanyo e sa nepahalang e ka lebisa ho liphetho tse tlase. Haeba litekanyetso li le tlase haholo, li kanna tsa se ke tsa thibela liminerale tsa gangue kapa tsa hasanya makhasi. Ka mohlala, ho flotation ea phosphate ore, haeba palo ea sodium hexametaphosphate e ekelitsoeng e sa lekana, liminerale tsa gangue li ka 'na tsa se ke tsa thibeloa hantle, e leng se etsang hore ho be le boemo bo tlaase ba phosphate concentrate.

• Ka lehlakoreng le leng, haeba tekanyo e phahame haholo, e ka 'na ea se ke ea eketsa litšenyehelo feela empa hape ea baka liphello tse ling tse mpe. Maemong a mang, sodium hexametaphosphate e feteletseng e ka boela ea thibela liminerale tse reretsoeng ho isa tekanyong e itseng, ho fokotsa sekhahla sa ho hlaphoheloa. Ka hona, ho khetha tekanyo e nepahetseng ka lipatlisiso tsa liteko le ho lokisa bothata sebakeng sa marang-rang ho bohlokoa bakeng sa ho fumana liphetho tse ntle ka ho fetisisa tsa ho phaphamala.

pH Boleng ba Pulp

2.Tšusumetso ea Lik'hemik'hale

• Boleng ba pH ba makhasi a flotation bo ama karabelo ea lik'hemik'hale tsa sodium hexametaphosphate. Libakeng tse fapaneng tsa pH, tekanyo ea ionization le mofuta oa lik'hemik'hale oa sodium hexametaphosphate li ka fetoha. Sebakeng se nang le asiti, phello ea eona ea ho thibela liminerale tse ling e ka fokola. Sebakeng se nang le alkaline e ngata, e ka 'na ea itšoara le lintho tse ling tse ka har'a makhasi, e amang mosebetsi oa eona o tloaelehileng. Ka mohlala, ha ho phaphamala ha liminerale tse ling tsa koporo - lead - zinki, ho boloka boleng ba pH bo loketseng (hangata bo pota-potileng 8 - 10) ho ka etsa bonnete ba hore sodium hexametaphosphate e thibela ka katleho liminerale tsa gangue le ho khothaletsa ho phaphamala ha liminerale tse shebiloeng.

fihlela qeto e

Sodium hexametaphosphate e bapala likarolo tse ngata tsa bohlokoa ho phaphameng ha liminerale, ho kenyeletsoa joalo ka Ho sithabela maikutlo le ya qhalakanang. Ts'ebeliso ea eona mefuteng e fapaneng ea flotation ea liminerale, joalo ka phosphate ore le non-ferrous metal ore flotation, e ntlafalitse haholo ts'ebetso le boleng ba karohano ea liminerale. Leha ho le joalo, ho sebelisa bokhoni ba eona ka botlalo, lintlha tse kang litekanyetso le pulp pH li hloka ho laoloa ka hloko. Ka nts'etsopele e tsoelang pele ea indasteri ea merafo, lipatlisiso tse ling mabapi le ts'ebeliso ea sodium hexametaphosphate ho flotation ea liminerale li ka lebisa mekhoeng e sebetsang hantle le e tsitsitseng ea ts'ebetso ea liminerale.
