Maupangiri Okwanira a Flotation Reagents mu Copper Ore Flotation

Ma reagents oyandama ndi ofunikira pakulekanitsa mchere wamkuwa wamtengo wapatali ndi miyala ya zinyalala panthawi yoyandama. Cholinga chachikulu cha kuyandama kwa mkuwa ndikutulutsa mkuwa womwe ungagulitsidwe. Kuti akwaniritse izi, ma reagents osiyanasiyana amagwiritsidwa ntchito, omwe amagawidwa m'magulu anayi akuluakulu: osonkhanitsa, abale, pH modifiers, ndi obalalitsa.

1. Osonkhanitsa a Copper Flotation

Otolera amagwira ntchito yofunika kwambiri pakuyandama kwa mkuwa pomamatira pamwamba pa mchere wamkuwa, kuwapanga kukhala hydrophobic. Izi zimathandiza kuti mchere wamkuwa ugwirizane ndi thovu la mpweya ndikukwera pamwamba pa selo yoyandama. Otolera wamba pakuyandama kwa mkuwa ndi ma xanthates ndi dithiophosphates (ma reagents akuda).

• Xanthates
  Xanthates monga ethyl xanthate ndi pentyl xanthate amagwiritsidwa ntchito kwambiri osonkhanitsa mkuwa zoyandama. Amatsuka bwino pamwamba pa mchere wamkuwa, kuwapangitsa kukhala hydrophobic ndipo motero kumakhala kosavuta kumangirira ku thovu la mpweya mu cell yoyandama.

• Dithiophosphates (Black Reagents)
  Ma reagents a dithiophosphate monga sodium diisobutyl dithiophosphate (black sodium reagent) ndi ammonium diisobutyl dithiophosphate (black ammonium reagent) amagwiritsidwanso ntchito kwambiri. Amagwiranso ntchito mofananamo polimbikitsa hydrophobicity ya mchere wamkuwa, kuthandizira kuyandama koyenera.

2. Frothers for Copper Flotation

Frothers amawonjezedwa m'maselo oyandama kuti apange thovu lokhazikika lomwe limanyamula mchere wamkuwa wa hydrophobic kupita pamwamba pa selo, komwe amatha kuchotsedwa.

• Mafuta a Pine
  Mafuta a pine ndi amodzi mwa mafuta omwe amagwiritsidwa ntchito kwambiri. Zimapanga chisanu chokhazikika chomwe chimabweretsa mchere wamkuwa pamwamba kuti utengedwe.

• Methyl Isobutyl Carbinol (MIBC)
  MIBC ndi mtundu winanso wotchuka, womwe umadziwika ndi zinthu zake zabwino kwambiri zotulutsa thovu komanso kukhazikika, zomwe zimathandizira kuyendetsa bwino ntchito.

• Mitundu ya Polyether Frothers
  Mankhwala a polyether monga polyethylene glycol ndi polypropylene glycol amagwiritsidwanso ntchito poyandama mkuwa. Ma frother awa amapereka thovu lokhazikika komanso amathandizira magwiridwe antchito abwinoko.

3. Zosintha za pH za Copper Flotation

Zosintha za pH zimayang'anira mikhalidwe yamankhwala a flotation slurry kuti achuluke kuchira mkuwa. Zosintha zambiri za pH zimaphatikizapo laimu, sodium hydroxide, ndi sulfuric acid.

• Laimu ndi sodium hydroxide
  Laimu ndi sodium hydroxide amagwiritsidwa ntchito kusintha slurry pH, kukhathamiritsa ntchito yamkuwa yoyandama. Kuwongolera bwino kwa pH ndikofunikira pakuyandama kosankha kwa mkuwa kuchokera ku mchere wina.

• Zoletsa ndi Activators
  Zoletsa ngati Sodium Cyanide ndi ferrous sulfate amagwiritsidwa ntchito kuteteza mchere wosafunikira kuti usayandama, ndikuwongolera kusankha kwa kuyandama kwa mkuwa. Zoyambitsa, monga copper sulfate, zimagwiritsidwa ntchito kupititsa patsogolo kuyandama kwa mchere wamkuwa wa sulfide.

4. Dispersants for Copper Flotation

Dispersants bwino kugawa reagents ndi olimba particles mu flotation slurry, kuonetsetsa kukhudzana bwino pakati pa mchere mkuwa ndi reagents flotation.

• Polyacrylamides
  Polyacrylamide ndi ambiri ntchito dispersant kumathandiza kupewa tinthu aggregation, kuonetsetsa imayenera reagent mogwirizana ndi mkuwa kuyandama.

• Epoxy resins
  Ma epoxy resins amagwiritsidwanso ntchito chifukwa cha kufalikira kwawo kopambana komanso zomatira, kupititsa patsogolo njira yoyandama.
