Tom qab siv cov txheej txheem ua yeeb yam hauv cov pob zeb hauv av, hauv cov txheej txheem frotation, cov nyhuv ntawm kev nce cov flotability ntawm cov zaub mov ntawm cov zaub mov muaj zog. Tus neeg sawv cev siv los hloov cov lus sib xyaw ua ke ntawm cov ntxhia saum npoo av thiab txhawb kev sib cuam tshuam ntawm cov neeg sau thiab cov pob zeb hauv cov activator.
Kev ua kom muaj peev xwm tuaj yeem raug faib ua: 1. Tshwm sim ua haujlwm; 2. Ua Haujlwm; 3. Sawv Rov Los; 4. Vulcanization.
1. Tshuav
Thaum ua cov ees ferrous polymetallic ores, cov ntxhia deg yuav nteg nti nrog qee cov soluble ntsev ions thaum lub sijhawm sib tsoo. Piv txwv li, thaum sphaalerite thiab tooj liab sulfide cov zaub mov, ib qho me me ntawm tooj liab sulfide cov zaub mov yuav ib txwm muaj oxidized mus rau hauv tooj liab sulfate tom qab ore. Lub cu2 + ions hauv slurry hnov qab nrog sphalerite nto kom qhib nws, ua rau nws nyuaj rau cais tooj liab thiab zinc. Nws yog ib qho tsim nyog los ntxiv qee qhov kev kho kom haum xws li txiv qaub lossis sodium carbonate rau nag "uas yuav ua kom muaj zog.
Thib ob, Peactivation
Txhawm rau xaiv cov ntxhia, ntxiv ib qho activator kom qhib nws. Thaum pyrite yog oxidized oxidized, sulfuric acid yog ntxiv rau yaj cov pyrite ua ntej flotation ua ntej flotation ua ntej flotation, nthuav tawm cov ntshiab saum npoo, uas tau txais txiaj ntsig rau kev muab tso.
peb.ricover
Nws hais txog cov zaub mov uas tau inhibited ua ntej, xws li sphalerite uas tau raug txwv los ntawm cyanide, thiab tuaj yeem sawv rov qab los ntawm kev ntxiv tooj liab sulfate.
Plaub.Vulcanization
Nws hais txog thawj zaug kho cov hlau oxide ore nrog sodium sulfide los ua ib txheej ntawm cov olide ore, thiab tom qab ntawd flotation nrog Xanthate.
Cov khoom siv ua haujlwm ntxhia siv tau ua raws li cov ua tau yog:
Sulfuric acid, sulfurous acid, sodium sulfide, tooj liab sulfate, sodium carbonate, sodium carbonate, sodium carbonate, sodium carbonate, socium carbonate, sevium carbonate, sevas fydroxide, cov kua qaub, barium, thiab lwm yam.
