Tus Neeg Sawv Cev Qib Siab

Nyob rau hauv qhov, tshwj tsis yog rau cov ntxhia partles xws li thee, graphite, muaj cov pob zeb hydrophibic, thiab tib yam yog qhov tseeb rau kev tso nyiaj kub. Ntxiv tus neeg sawv cev tuaj yeem hloov kho hydrophilicity ntawm cov ntxhia cov lus thiab ua rau hydrophobicity ua kom lawv ntab. Tus neeg sawv cev no feem ntau hu ua ib tug collector. Cov neeg ua kom cov neeg sawv cev feem ntau yog polar cov neeg sau thiab cov sau polar. Cov polar cov neeg sau tau muaj cov pawg polar uas tuaj yeem cuam tshuam nrog cov npoo ntawm cov ntxhia thiab cov pawg tsis muaj cov nyhuv hydrophobic. Thaum hom kev sau tau adsorbed rau saum npoo ntawm cov ntxhia cov nplais thiab cov pawg tsis tau npaj rau hauv cov kab ke thiab cov pab pawg tsis ua rau muaj cov yeeb yaj kiab hydrophobic, yog li ua cov ntxhia lub chaw floatable. Cov. Rau cov kub cuam tshuam nrog sulfide ntxhia depits xws li tooj liab, txhuas, thiab lwm yam. Piv txwv li, Alkyl (Ethylene, Butyl, thiab lwm yam) sodium dithiocarbonate (potassium), tseem hu ua, cov hu ua Xanthate. Piv txwv li, NAS2C · · · · · · · · ·-ncia polymetallic ores, ethyl xanthate thiab butyl xanthate feem ntau siv. Alkyl dithiophphats lossis lawv cov ntsev, xws li (ro) 2pssh, qhov twg r yog ib pab pawg alkyl, feem ntau yog hu ua tshuaj dub.

Piv txwv li, Alkyl (Ethylene, Butyl, thiab lwm yam) sodium dithiocarbonate (potassium), tseem hu ua, cov hu ua Xanthate. Piv txwv li, NAS2C · · · · · · · · ·-ncia polymetallic ores, ethyl xanthate thiab butyl xanthate feem ntau siv. Alkyl dithiophphats lossis lawv cov ntsev, xws li (ro) 2pssh, qhov twg r yog ib pab pawg alkyl, feem ntau yog hu ua tshuaj dub. Alkyl Disulfide Salts thiab Ester derivatives kuj feem ntau siv cov neeg sau rau cov tshuaj pleev cov khoom ntxhiv pob zeb. Nws tseem yog ib qho uas siv tau siv rau kev flotation ntawm kub-bearing polymetallic sulfide ees, thiab feem ntau siv ua ke nrog Xanthate. Cov lwg me me ntawm cov neeg sau nyiaj hauv ionic

Cov pab pawg npoo npoo av nrog cov pab pawg hydrophilic thiab ua kom cov pa hluav taws xob tsis sib haum thiab ua kom cov cua kom yooj yim rau hauv cov npuas thiab ruaj khov npuas. Tus neeg sawv cev foaming thiab cov sau ua ke rau adsorb nyob rau saum npoo ntawm cov ntxhia cov nplais, ua rau cov ntxhia kom ntab. Cov neeg sawv cev ua npuas dej uas nquag siv suav nrog: pine roj, penolic acids sib xyaw nrog cov roj tsis muaj roj, omeric hexanol lossis bungent cawv, ether cawv thiab ntau yam esters.

Cov kev kho tuaj yeem muab faib ua tsib pawg: (1) PH kho kom haum. Nws yog siv los kho cov phenurry kom tswj tau cov khoom ntawm cov ntxhia thiab cov txiaj ntsig tshuaj lom neeg ntawm ntau lwm yam tshuaj lom neeg, yog li txhim kho cov flotation cov nyhuv. Hauv cov txheej txheem tshuaj lom neeg, nws tseem yuav tsum tau kho tus nqi ntawm tus cwj mem. Feem ntau siv tau muaj xws li kua qaub, sodium carbonate, thiab sulfuric acid. Thaum xaiv cov kub, feem ntau cov txiv qaub yog txiv qaub thiab sulfuric acid. (2) activator. Nws tuaj yeem txhim kho lub peev xwm ntawm cov ntxhia tso nyiaj thiab cov neeg sau los ua kom zoo thiab ntab cov ntxhia pob zeb. Cov kub-muaj cov txhuas xim oxide ore yog tshuab txais thiab tom qab ntawd flotated siv Xanthate thiab lwm cov neeg sau khoom. (3) Aibitors: txhim kho lub hydrophilicity ntawm cov ntxhia tso thiab tiv thaiv cov ntxhia pob zeb los ntawm kev sib txuas, yog li inhibiting lawv ntab.
Piv txwv li, nyob rau hauv cov txheej txheem uas nyiam ua, kua qaub yog siv los txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau ua cov hmoov txhuv nplej siab xws li cov hmoov txhuv nplej siab thiab cov pos hniav) siv raws li cov tub sab ua kom tiav ntau lub hom phiaj. Lub hom phiaj ntawm cov hlau sib cais thiab cov twj ywm. (4) flocculant. Kev sib sau ua ke ntawm cov ntxhia pob zeb rau hauv cov khoom loj los ua kom nrawm lawv cov dej nrawm nrawm; Siv flocculation kev xaiv los ua flocculation-desliming thiab flocculation-flotation. Feem ntau siv flocculants suav nrog polyamide thiab cov hmoov txhuv nplej siab. (5) Dispersant. Nws tiv thaiv kev sib sau ua ke ntawm cov ntxhia uas zoo thiab ua rau lawv nyob hauv monomer xeev. Nws cov nyhuv yog raws nraim qhov rov qab ntawm qhov ntawd ntawm flocculants. Cov siv uas nquag siv suav nrog cov dej dej muaj xws li cov kua dej iav, phosphate, thiab lwm yam.
