Litšebelisano tsa Sodium Sulfide le Li-reagents tse ling ts'ebetsong ea Flotation

Tšimong ea Ts'ebetso ea liminerale, flotation ke mokhoa o sebelisoang haholo oa ho arola liminerale tsa bohlokoa ho tswa ho gangue. Sodium sulfide e bapala karolo ea bohlokoa ts'ebetsong ena, haholo-holo e sebelisoa ho lokisa boleng ba pH ba makhasi, sulfidize, khatello ea maikutlo le ho hlobola bokaholimo ba liminerale. Likamano tsa eona le Bokelli, Barab'eso, 'me Bolaoli li rarahane 'me li na le tšusumetso e kholo ho sebetsa hantle le ho khetha ha flotation.

Litšebelisano le Babokelli

Tšusumetso ho Babokelli ba Liminerale tsa sulfide

Bakeng sa babokelli ba tloaelehileng ba liminerale tsa sulfide tse kang xanthates le dithiophosphates, ha litekanyetso li behoa. Sodium sulfide e nepahetse, e ka ntlafatsa hydrophobicity ea bokaholimo ba liminerale tsa sulfide, e nolofalletsa babokelli ho bapa hantle holim'a bokaholimo ba liminerale le ho ntlafatsa ho phaphamala ha liminerale. Leha ho le joalo, ha sodium sulfide e feta, e tla etsa filimi ea hydrophilic holim'a liminerale tsa sulfide, e thibela ho ata ha ba bokellang 'me kahoo e bapala karolo ea ho thibela. Ka mohlala, ho phaphamala ha ore ea koporo-sulfur, tekanyo e loketseng ea sodium sulfide e ka khothalletsa pokello ea chalcopyrite ka xanthate, ha chelete e ngata e tla thibela ho phalla ha chalcopyrite.

Tšusumetso ho Babokelli ba Liminerale tsa Oxide

Ha ho phaphamala ha liminerale tsa oxide, sodium sulfide e ka sulfidize holim'a liminerale tsa oxide, ea li lumella ho bokelloa ke babokelli ba liminerale tsa sulfide. Ka mohlala, ha ho sebelisoa babokelli ba acid e mafura ho phaphamala cerussite, sodium sulfide pele sulfidizes holim'a cerussite 'me joale interacts le mafura acid e pokello, ho ntlafatsa flotation phello ea cerussite.

Likamano le Frothers

Sodium sulfide ka boeona ha e na thepa e phophomang, empa e ka ama thepa ea makhasi le boemo ba holim'a liminerale, ka hona e susumetsa phello e phophomang ea li-frothers. Palo e loketseng ea sodium sulfide e etsa hore hydrophobicity ea holim'a liminerale e be e loketseng, e loketseng ho hokelloa ha li-bubble ho liminerale, ho ntlafatsa phello ea aeration le botsitso ba foam ea frothers. Leha ho le joalo, palo e feteletseng ea sodium sulfide e tla hasanya slime e ntle ka har'a makhasi, e eketse ponahalo ea makhasi, e etse hore foam e khomarele, 'me e ama botsitso le mokelikeli oa foam, e leng se sa khoneng ho senya foam ea flotation le karohano ea concentrate.

Litšebelisano le Balaoli ba Bang

Synergistic Effect e nang le pH Regulators

Sodium sulfide e hydrolyzes ho ba alkaline mme e ka sebetsa ka kopanelo le balaoli ba bang ba pH joalo ka lime le sodium k'haboneho lokisa boleng ba pH ba pulp hammoho. Mohlala, ha ore ea lead-zinc e phaphamala, sodium sulfide le lime hangata li sebelisoa hammoho ho boloka alkaline ea pulp, ho thibela liminerale tse sa hloekang tse kang pyrite, le ho ntlafatsa khetho ea flotation ea ore ea lead-zinc.

Likamano le li-Depressants

Sodium sulfide e na le litlamorao tse ts'oanang tsa inhibitory ho li-depressants tse ling joalo ka cyanide le khalase ea metsi. Maemong a mang, li ka sebelisoa hammoho ho ntlafatsa phello ea inhibitory. Ka mohlala, ha ho phaphamala ha tšepe ea koporo-lead-zinc polymetallic ore, tšebeliso e kopantsoeng ea sodium sulfide le cyanide e ka matlafatsa ho thibela sphalerite le pyrite, ho finyella karohano e sebetsang ea koporo-leto ho tloha zinki-sulfure. Leha ho le joalo, tlhokomelo e lokela ho lefshoa ho laola litekanyetso le tatellano ea tlatsetso; ho seng joalo, thibelo e feteletseng e ka 'na ea etsahala, e amang lebelo la ho hlaphoheloa.

Litšebelisano le li-Activators

Sodium sulfide e na le phello ea ts'ebetso ho liminerale tse ling tse thibetsoeng 'me e ka sebelisoa hammoho le li-activator. Ka mohlala, ka karohano ea flotation ea ore ea sulfide koporo-lead, galena e thibetsoeng ke cyanide e ka sebelisoa ke sodium sulfide ebe e bokelloa ke ethyl thionocarbamate ho finyella karohano ea koporo le loto. Ka nako e ts'oanang, sodium sulfide e ka boela ea ama phello ea li-activators tse ling. Mohlala, palo e fetelletseng ea sodium sulfide e ka ja li-ion tse sebetsang ka har'a makhasi, ho fokotsa ts'ebetso ea li-activator.

Qetellong, ho utloisisa litšebelisano tsa sodium sulfide le li-reagents tse ling ts'ebetsong ea ho phalla ho bohlokoa haholo bakeng sa ho ntlafatsa ts'ebetso ea ho phalla, ho ntlafatsa sekhahla sa ho hlaphoheloa le boemo ba liminerale tsa bohlokoa, le ho fokotsa litšenyehelo tsa ho sebetsa liminerale. Baenjineri ba ts'ebetso ea liminerale ba hloka ho lokisa ka hloko litekanyetso le tatellano ea li-reagents tse fapaneng ho latela thepa e ikhethileng ea ore ho fihlela liphetho tse ntle ka ho fetisisa tsa ho phaphamala.
