Tom qab kev siv cov ntxhia ua cov activator: Hauv cov txheej txheem flotation, cov nyhuv ntawm kev ua kom lub flotability ntawm cov ntxhia yog hu ua activation.Tus neeg sawv cev siv los hloov qhov muaj pes tsawg leeg ntawm cov pob zeb hauv av thiab txhawb kev sib cuam tshuam ntawm cov khoom sau thiab cov pob zeb hauv av hu ua activator.
Kev ua kom muaj zog tuaj yeem muab faib ua: 1. Kev ua kom muaj zog;2. Preactivation;3. Kev Sawv Rov Los;4. Vulcanization.
1. Kev ua kom muaj zog
Thaum ua cov non-ferrous polymetallic ores, cov pob zeb hauv av yuav spontaneously react nrog ib co soluble ntsev ions thaum lub sij hawm sib tsoo txheej txheem.Piv txwv li, thaum sphalerite thiab tooj liab sulfide minerals coexist, ib tug me me ntawm tooj liab sulfide minerals yuav yeej ib txwm oxidized rau tooj liab sulfate tom qab cov ore yog mined.Lub Cu2 + ions nyob rau hauv slurry teb nrog sphalerite nto los qhib nws, ua rau nws nyuaj rau cais tooj liab thiab zinc.Nws yog ib qho tsim nyog yuav tsum tau ntxiv qee cov tshuaj kho xws li txiv qaub lossis sodium carbonate kom ua rau nag, nrog rau qee qhov "tsis pom kev" uas yuav ua rau muaj kev ua kom muaj zog.
Thib ob, preactivation
Txhawm rau xaiv cov ntxhia, ntxiv ib qho activator kom qhib nws.Thaum pyrite yog oxidized hnyav heev, sulfuric acid yog ntxiv rau yaj cov oxide zaj duab xis nyob rau saum npoo ntawm pyrite ua ntej flotation, nthuav tawm qhov chaw tshiab, uas yog qhov zoo rau flotation.
peb.rov qab
Nws hais txog cov zaub mov uas tau inhibited ua ntej, xws li sphalerite uas tau inhibited los ntawm cyanide, thiab tuaj yeem sawv rov los los ntawm kev ntxiv tooj liab sulfate.
Plaub.vulcanization
Nws yog hais txog thawj zaug kho cov hlau oxide ore nrog sodium sulfide los tsim ib txheej ntawm hlau sulfur ntxhia zaj duab xis rau saum npoo ntawm oxide ore, thiab tom qab ntawd flotation nrog xanthate.
Mineral processing reagents siv los ua activators yog:
Sulfuric acid, sulfurous acid, sodium sulfide, tooj liab sulfate, oxalic acid, txiv qaub, sulfur dioxide, lead nitrate, sodium carbonate, sodium hydroxide, lead ntsev, barium ntsev, thiab lwm yam.
