tooj liab sulfate, uas zoo nkaus li xiav los yog xiav-ntsuab crystals, yog ib tug dav siv activator nyob rau hauv sulfide ore flotation.Nws yog tsuas yog siv los ua tus activator, regulator thiab inhibitor los kho pH tus nqi ntawm slurry, tswj ua npuas ncauj tsim thiab txhim kho Lub peev xwm ntawm cov zaub mov muaj peev xwm ua kom muaj zog ntawm sphalerite, stibnite, pyrite thiab pyrrhotite, tshwj xeeb tshaj yog sphalerite uas yog inhibited los ntawm txiv qaub. los yog cyanide.
Lub luag haujlwm ntawm tooj liab sulfate hauv cov ntxhia flotation:
1. Siv ua activator
Muaj peev xwm hloov cov khoom hluav taws xob ntawm cov pob zeb hauv av thiab ua cov pob zeb hauv av hydrophilic.Qhov hydrophilicity no tuaj yeem ua rau thaj chaw sib cuag ntawm cov pob zeb hauv av thiab dej, ua rau nws yooj yim dua rau cov pob zeb hauv av.tooj liab sulfate kuj tuaj yeem tsim cations nyob rau hauv cov ntxhia slurry, uas yog ntxiv adsorbed rau saum npoo ntawm cov ntxhia, ua rau nws cov hydrophilicity thiab buoyancy.
Lub activation mechanism suav nrog ob yam hauv qab no:
①.Cov tshuaj tiv thaiv metathesis tshwm sim ntawm qhov chaw ntawm cov pob zeb hauv av kom tsim tau cov yeeb yaj kiab ua kom muaj zog.Piv txwv li, tooj liab sulfate yog siv los qhib sphalerite.Lub vojvoog ntawm divalent tooj liab ions zoo ib yam li lub vojvoog ntawm zinc ions, thiab solubility ntawm tooj liab sulfide yog ntau me dua li ntawm zinc sulfide.Yog li ntawd, tooj liab sulfide zaj duab xis tuaj yeem tsim rau ntawm qhov chaw ntawm sphalerite.Tom qab cov yeeb yaj kiab tooj liab sulfide tsim, nws tuaj yeem cuam tshuam nrog xanthate tau yooj yim, kom lub sphalerite tau qhib.
②.Tshem tawm cov inhibitor ua ntej, thiab tom qab ntawd tsim cov yeeb yaj kiab ua haujlwm.Thaum sodium cyanide inhibits sphalerite, ruaj khov zinc cyanide ions yog tsim nyob rau saum npoo ntawm sphalerite, thiab tooj liab cyanide ions ruaj khov dua zinc cyanide ions.Yog hais tias tooj liab sulfate ntxiv rau sphalerite slurry uas yog inhibited los ntawm cyanide, cov cyanide radicals nyob rau saum npoo ntawm sphalerite yuav poob tawm, thiab cov dawb tooj liab ions yuav hnov mob nrog cov sphalerite los ua ib qho kev ua yeeb yaj kiab ntawm tooj liab sulfide, yog li ua kom lub cev muaj zog. sphalerite.
2. Siv los ua tus tswj hwm
Tus nqi pH ntawm slurry tuaj yeem hloov kho.Ntawm tus nqi pH uas tsim nyog, tooj liab sulfate tuaj yeem hnov mob nrog hydrogen ions ntawm cov pob zeb hauv av los tsim cov tshuaj lom neeg uas ua ke nrog cov pob zeb hauv av, ua kom cov dej ntws thiab buoyancy ntawm cov pob zeb, yog li txhawb cov nyhuv flotation ntawm cov pob zeb kub.
3. Siv los ua ib qho inhibitor
Anions tuaj yeem tsim nyob rau hauv slurry thiab adsorbed rau saum npoo ntawm lwm yam minerals uas tsis tas yuav flotation, txo lawv cov hydrophilicity thiab buoyancy, yog li tiv thaiv cov minerals los ntawm floated ua ke nrog kub minerals.Copper sulfate inhibitors feem ntau ntxiv rau cov slurry kom cov zaub mov uas tsis tas yuav flotation hauv qab.
4. Siv raws li cov ntxhia qhov chaw hloov kho
Hloov cov tshuaj thiab lub cev lub cev ntawm cov ntxhia pob zeb.Hauv kub ore flotation, cov khoom hluav taws xob thiab hydrophilicity ntawm cov pob zeb hauv av yog qhov tseem ceeb flotation.Copper sulfate tuaj yeem tsim tooj liab oxide ions hauv cov ntxhia slurry, hnov mob nrog cov hlau ions ntawm cov pob zeb hauv av, thiab hloov nws cov khoom siv tshuaj lom neeg.tooj liab sulfate kuj tuaj yeem hloov qhov hydrophilicity ntawm cov pob zeb hauv av thiab ua rau thaj chaw sib cuag ntawm cov zaub mov thiab dej, yog li txhawb nqa cov nyhuv flotation ntawm cov mines kub.
