Kev ceev faj rau kev siv thiab khaws cia ntawm xanthate

[kev piav qhia dav dav]Xanthate yog flotation sulfide ntxhia, xws li galena, sphalerite, actinide, pyrite, mercury, malachite, natural silverand natural gold, Nws yog cov khoom siv ntau tshaj plaws.

Nyob rau hauv tus txheej txheem ntawm flotation thiab tau txais txiaj ntsig, txhawm rau kom muaj txiaj ntsig zoo sib cais cov zaub mov muaj txiaj ntsig los ntawm gangue cov zaub mov, lossis cais ntau yam muaj txiaj ntsig minerals, nws yog qhov yuav tsum tau ntxiv qee cov reagents los hloov lub cev thiab tshuaj lom neeg ntawm cov pob zeb hauv av thiab cov khoom ntawm nruab nrab. .Cov reagents no raug hu ua flotation reagents.Xanthate yog cov khoom siv feem ntau siv rau flotation ntawm sulfide ores.

Xanthate muab faib ua ethyl xanthate, amyl xanthate thiab lwm yam.Xanthate nrog tsawg dua 4 carbon atoms nyob rau hauv pawg hydrocarbon, collectively hu ua low-grade xanthate, Xanthate nrog ntau tshaj 4 carbon atoms yog collectively xa mus rau advanced xanthate. kev txiav txim kom xanthate tag nrho nws cov kev ua tau zoo, Kev saib xyuas yuav tsum tau them rau cov hauv qab no thaum siv thiab khaws cia:

1. Siv nyob rau hauv alkaline pulp kom deb li deb tau.Vim xanthate yog yooj yim dissociation nyob rau hauv dej, nws yuav tshwm sim hydrolysis thiab decomposition.Yog hais tias ib co tej yam kev mob xav kom nws yuav tsum tau siv nyob rau hauv acid pulp, advanced xanthate yuav tsum tau siv.Vim siab heev xanthate disintegrates ntau qeeb dua qib qis xanthate hauv acid pulp.

2. Cov tshuaj xanthate yuav tsum tau siv raws li qhov xav tau, tsis txhob sib tov ntau dhau ib zaug, thiab tsis txhob sib tov nrog dej kub.Ntawm qhov chaw tsim khoom, xanthate feem ntau formulated rau hauv 1% aqueous tov rau siv.Vim xanthate yog yooj yim rau hydrolyze, decompose thiab tsis, Yog li tsis txhob sib tw ntau dhau ntawm ib lub sijhawm.Nws tsis tuaj yeem npaj nrog dej kub, vim xanthate yuav decompose sai dua thaum tshav kub.

3. Txhawm rau tiv thaiv xanthate los ntawm kev puas tsuaj thiab tsis ua haujlwm, nws yuav tsum tau khaws cia rau hauv qhov chaw kaw, tiv thaiv kev sib cuag nrog huab cua noo thiab dej, Khaws rau hauv qhov chaw txias, qhuav thiab qhov cua zoo, tsis txhob cua sov, xyuam xim tiv thaiv hluav taws.
