(1) dichromate txoj kev: uas yog, nrog dichromate inhibition ntawm galena thiab flotation ntawm tooj liab minerals.
(2) txoj kev cyanide: uas yog, nrog cyanide inhibition ntawm tooj liab cov zaub mov thiab flotation ntawm txhuas cov zaub mov.
(3) Ferrocyanide txoj kev: thaum lub thib ob tooj liab ntxhia cov ntsiab lus nyob rau hauv ore yog siab heev, cov nyhuv ntawm ob txoj kev saum toj no tsis zoo txaus, lub sij hawm no, yog hais tias cov hlau lead ntsiab lus nyob rau hauv lub ore yog siab, ces siv ferrocyanide. (daj thiab liab ntshav ntsev) inhibit qhov thib ob tooj liab minerals flotation ntawm txhuas cov zaub mov; yog tias cov ntsiab lus ntawm cov hlau lead ntau dua cov tooj liab, koj yuav tsum sim ob qhov kev pab cuam hauv qab no.
(4) Sulfurous acid method (sulfur dioxide method): uas yog, nrog sulfur dioxide roj los yog sulfurous acid kev kho mob ntawm mixed concentrates, yog li ntawd cov hlau lead minerals yog inhibited thiab tooj liab minerals yog activated. Txhawm rau ntxiv dag zog rau qhov inhibition, tuaj yeem ntxiv cov poov tshuaj dichromate lossis zinc dithionite, thiab lwm yam, tuaj yeem ua kom sov li slurry (cov txheej txheem cua sov flotation), thiab thaum kawg yuav tsum tau siv rau cov kua qaub slurry pH hloov rau 5-7 , thiab tom qab ntawd flotation ntawm tooj liab minerals.
(5) sodium sulfite, hlau sulfate txoj kev: uas yog, siv sodium sulfite thiab hlau sulfate raws li ib tug sib tov ntawm inhibitors, thiab sulfuric acid acid acidification ntawm slurry, stirring nyob rau hauv cov kev mob ntawm pH=6-7, inhibition ntawm galena thiab flotation ntawm tooj liab minerals.
Ib qho ntawm cov laj thawj tseem ceeb rau qhov nyuaj ntawm kev sib cais cov tooj liab-cov hmoov txhuas sib xyaw ua ke yog vim muaj cov tshuaj lom neeg ntau dhau (khob thiab foaming agents) hauv cov concentrates. Kev tshem tawm cov tshuaj ntau dhau los ntawm slurry thiab tshem tawm cov yeeb yaj kiab trapper los ntawm cov pob zeb hauv av ua ntej kev sib cais ntawm qhov sib xyaw ua ke tuaj yeem txhim kho kev sib cais ntawm cov sib xyaw kom zoo.
Txawm koj xav taucov kav dej tooj liab, tooj liab rods ,tooj liab daim hlau, peb muaj cov khoom thiab kev txawj ntse kom tau raws li koj xav tau.
