Txo cov tshuaj poob ntawm sodium cyanide tov - Tiv thaiv lub hauv paus

sodium cyanide cov kev daws teeb meem ua lub luag haujlwm tseem ceeb hauv kev rho tawm cov hlau muaj txiaj ntsig, tshwj xeeb tshaj yog hauv kev lag luam kub mining. Muab lawv cov kev siv dav dav, kev tswj xyuas kev ruaj ntseg ntawm cov kev daws teeb meem no yog qhov tseem ceeb heev. Sodium cyanide's chemical reactivity, txawm li cas los xij, ua rau nws yooj yim rau kev poob loj yam tsis muaj kev tiv thaiv zoo.

Lub luag haujlwm ntau yam ntawm kev tiv thaiv Alkali

Kev Tiv Thaiv Kev Ncaj Ncees

Ntxiv qhov tsim nyog kom muaj nuj nqis ntawm alkali-termed tiv thaiv alkali- hais txog qhov teeb meem tsis ruaj khov. Nws ua hauj lwm raws li ib tug stabilizing neeg sawv cev, txo cov tshuaj losses Sodium cyanide.

Neutralizing Reactive Compounds

Cov alkali tiv thaiv kuj tseem ua rau tsis muaj zog carbon dioxide nyob rau hauv cov kua. Tsis tas li ntawd, nws tawm tsam cov kua qaub uas tsim los ntawm kev oxidation ntawm cov zaub mov sulfide, tswj kom muaj kev sib npaug ntawm cov tshuaj lom neeg.

Cov Pitfalls ntawm Tshaj Alkalinity

Txawm hais tias nws qhov tseem ceeb, qhov siab dhau ntawm alkalinity tuaj yeem cuam tshuam cov txheej txheem rho tawm. Rau ib qho, nws qeeb tus nqi ntawm cov kub yaj hauv cov tshuaj cyanide. Tsis tas li ntawd, nws ua rau muaj kev noj ntau ntxiv ntawm zinc thaum lub sij hawm hloov chaw, uas yog qhov tseem ceeb rau kev rov qab los ntawm kub.

Txiv qaub: Cov Kev Tiv Thaiv Zoo Tshaj Alkali

Tus nqi - Kev tswj hwm Alkalinity zoo

Txiv qaub yog ib qho kev xaiv nrov rau kev tswj xyuas qhov xav tau alkalinity vim nws cov nqi - kev ua tau zoo. Nws ua tau zoo ua haujlwm ntawm kev tiv thaiv alkali.

Flocculation Cov txiaj ntsig

Tshaj li alkalinity tswj, txiv qaub pab nyob rau hauv lub flocculation ntawm nplua - grained minerals thiab slimes nyob rau hauv lub pulp. Qhov no txhim kho kev sib cais thiab kev ua haujlwm ntawm cov zaub mov, txhim kho kev ua haujlwm tag nrho.

Optimal Parameter Control nyob rau hauv Industrial Chaw

pH thiab Calcium Oxide Concentration

Hauv kev tsim khoom lag luam, tswj cov tshuaj pH ntawm 11 thiab 12 yog qhov pom zoo. Qhov no yog ua tiav los ntawm kev ua tib zoo tswj cov concentration ntawm dawb calcium oxide (CaO) mus rau 1 - 3 qhov chaw ntawm kaum txhiab. Kev tswj xyuas meej ntawm cov kev txwv no yog qhov tseem ceeb los xyuas kom meej tias kev ua haujlwm zoo ntawm cov khoom siv txheej txheem cyanidation. Nws ua kom zoo tshaj qhov rov qab los ntawm cov hlau muaj txiaj ntsig thaum txo qis tshuaj lom neeg thiab cov nqi tsim khoom.
