Kev siv thiab muab tshuaj ntau ntawm sodium sulfite hauv kev sib sau hnav khaub ncaws

Kev siv cov metabisulfite sodium hauv cov ntxhia txheej txheem, kev siv cov kev pab thiab kev tshuaj ntau. Sodium metabisulfite feem ntau yog siv los ua tus inhibitor hauv kev ua ntxhia. Cov hauv qab no yog cov ntaub ntawv cuam tshuam ntawm nws kev siv, kev siv cov kev pab thiab kev tshuaj:

Siv:
Inhibition ntawm sphaalerite thiab pyrite: sodium pyrosulfite decomposes tooj liab, oxidizes cov txheej txheem ntawm zinc hydroxide, thiab yog li inhibits sphalerite; Nws tseem muaj cov nyhuv inhibitia rau pyrite. Txawm li cas los xij, nws tsis muaj qhov cuam tshuam los ntawm Chalcopyrite, tab sis tuaj yeem ua kom chalcopyrite.
Cov Lus Taw Qhia:
Npaj cov kev daws teeb meem: Dhuav Sodium metabisulfite hauv dej los npaj kev daws teeb meem ntawm qee qhov kev xav tau. Vim tias sulfite yog yooj yim oxidized thiab tsis muaj txiaj ntsig nyob rau hauv slurry, kev daws yuav tsum tau npaj rau hnub ntawm kev siv.
Daim ntawv qhia ntxiv: Txhawm rau tswj hwm qhov ruaj ntseg ntawm thaj av Inhibitions, lub stide cov txheej txheem feem ntau yog saws38.
Siv ua ke nrog lwm tus neeg sawv cev: piv txwv li, hauv qhov txiaj ntsig ntawm Calcium chloride, polyamine, sodium humate, etc. los tsim cov inhibitor sib xyaw. Thaum siv, Ore thiab txiv qaub yog thawj hauv av; Tom qab ntawd cov slurry raug xa mus rau cov flotation tshuab, thiab cov neeg sawv cev ib pawg yog ntxiv rau kev ntxhib siab, middlings thiab ua haujlwm tom ntej24.
Ntse:
Tsis muaj tus nqi ruaj khov rau cov nqi ntawm sodium metabisulfite, uas yuav cuam tshuam nrog ntau yam cuab yeej, thiab lwm yam. Qhov feem ntau hais lus yuav tsum tau txiav txim siab raws cov kev qhia tshwj xeeb Cov ntxhia ua haujlwm. Hauv qee qhov kev xeem thiab kev tsim khoom tiag tiag, cov ntau lawm tshuaj, cov ntau npaum ntawm sodium metabisulfite yuav txawv ntawm ob peb gram kom kaum ntawm grams lossis txawm ntau rau ib tuj ntawm ore24. Piv txwv li, rau qee cov ores nrog cov ntsiab lus siab zoo nkauj thiab cov ntsiab lus pyrite, ib qho kev noj haus ntau ntau ntawm sodium metabisulfite tej zaum yuav tsum tau ua tiav cov nyhuv inhibition zoo; Thiab rau ores nrog ntau cov composition, nws kuj tseem tsim nyog xav txog cov nyhuv synergistic nrog lwm tus neeg sawvdum los txiav txim ntau npaum li cas ntawm Sodium Metabisulfite.

Hauv ntej, thaum siv sodium metabisulfite nyob rau hauv mine kev hnav khaub ncaws, yuav tsum tau twv thiab siv cov txheej txheem uas haum tshaj plaws thiab kev txhim kho kev hnav khaub ncaws ua haujlwm thiab ore.
