Kev tshawb xyuas luv luv ntawm lub luag haujlwm ntawm tooj liab sulfate nyob rau hauv ore resenticiation thiab flotation

Tooj liab sulfate, uas pom raws li xiav lossis xiav-ntsuab muaju, yog ib tus neeg siv dav dav dav hauv sulfide ore flotation. Nws yog tsuas yog siv los ua tus activator, kev tswj hwm thiab txhim kho cov kab ke ntawm spurry, cov pyrrhotite, tshwj xeeb yog tshuaj tiv thaiv los ntawm txiv qaub lossis cyanide.

Lub luag haujlwm ntawm tooj liab sulfate hauv cov ntxhia flotation:

1. Siv raws li activator

Tuaj yeem hloov cov hluav taws xob hluav taws xob ntawm cov ntxhia cov chaw thiab ua kom cov ntxhia saum npoo cua hydrophilic. Qhov hydrophilicity tuaj yeem nce thaj tsam ntawm ntawm thaj chaw ntawm cov ntxhia thiab dej, ua rau nws yooj yim dua rau cov ntxhia kom ntab. Tooj liab sulfate tseem tuaj yeem tsim cov kab ntawv hauv cov ntxhia pob zeb, uas yog ntxiv rau saum npoo ntawm cov ntxhia, nce nws hydrophilicity thiab buoyancy.

Kev ua kom lub tshuab ua kom muaj ob yam li hauv qab no:

①. Cov tshuaj tiv thaiv metathesis tshwm sim nyob rau saum npoo ntawm cov ntxhia pob zeb los ua yeeb yaj kiab ua kom zoo. Piv txwv li, tooj liab sulfate yog siv los qhib sphalerite. Lub vojvoog ntawm cov tooj liab ions zoo ib yam li lub vojvoog ntawm lub vojvoog ntawm tooj liab ntawm tooj liab sulfide yog ntau dua li ntawm zinc sulfide. Yog li ntawd, lub tooj liab sulfide zaj duab xis tuaj yeem tsim nyob rau saum npoo ntawm sphalerite. Tom qab lub tooj liab sulfide zaj duab xis yog tsim, nws tuaj yeem sib cuam tshuam yooj yim nrog tus sau Xanthate, kom tus sphalerite tau qhib.

②. Tshem tawm cov inhibitor ua ntej, thiab tom qab ntawd ua yeeb yaj kiab ua kom tiav. Thaum sodium cyanide inhibits sphalerite, ruaj khov zinc cyanide ions yog tsim nyob rau saum npoo ntawm sphalerite, thiab tooj liab cyanide ions muaj ruaj khov dua li zinc cyanide ions. Yog tias tooj liab sulfate yog ntxiv rau sphalerite slurry uas yog inhibited los ntawm sphalerite los tsim zaj duab xis ntawm tooj liab sulfide, yog li ua kom lub sphaalerite.

2. Siv raws li kev tswj hwm

Tus nqi PHF ntawm cov slurry tuaj yeem hloov kho. Ntawm tus nqi pH uas tsim nyog, tooj liab sulfate tuaj yeem hnov ​​mob nrog cov tshuaj ntxuav cov ntxhia, yog li txhawb cov flotation nyhuv ntawm cov kub mines.

3. Siv los ua tus inhibitor

Anesions tuaj yeem tsim nyob rau hauv cov slurry thiab adsorbed ntawm lwm cov minerals uas tsis tas ua kev tiv thaiv cov minerals los ntawm kev ua ke nrog cov zaub mov kub. Tooj liab sulfate inibitors feem ntau ntxiv rau cov slurry kom khaws cov zaub mov uas tsis xav tau cov pas dej hauv qab.

4. Siv raws li cov ntxhia nto hloov kho

Hloov cov tshuaj thiab lub cev ntawm lub cev ntawm cov ntxhia cov chaw. Nyob rau hauv kub ore flotation, cov hluav taws xob hluav taws xob thiab hydrophilicity ntawm cov ntxhia saum npoo yog qhov tseem ceeb flotation yam. Tooj liab sulfate tuaj yeem sau tooj liab oxide ions nyob rau hauv cov ntxhia, thiab hloov nws cov khoom nto nkaus. Tooj liab sulfate kuj tseem tuaj yeem hloov kho cov ntxhia npoo thiab nce thaj tsam ntawm cov zaub mov thiab dej ua ke ntawm cov flotation nyhuv ntawm cov kub mines.
