Kev Kho Cyanide hauv Kub Leaching Tailings

Qhov Prevalence ntawm Cyanidation thiab Danger ntawm Cyanide

Feem ntau cov chaw khawb kub thoob ntiaj teb siv tshuaj cyanidation ntau heev thiab yuav tseem muaj ntau ntxiv rau xyoo tom ntej. Txawm li cas los xij, Cyanide yog ib yam tshuaj lom uas txaus ntshai heev. Nws muaj nyob rau hauv cov dej khib nyiab thiab cov quav ciab tuaj yeem cuam tshuam loj heev rau tib neeg thiab ib puag ncig. Yog li, nws yog ib qho tseem ceeb kom tswj cov tshuaj lom no.

Cyanide Leaching Txheej Txheem thiab Nws Los ntawm - cov khoom

Kev rho tawm cyanide hloov kub mus ua cov cyanide complexes uas yaj tau hauv dej thiab tam sim no yog cov txheej txheem siv ntau tshaj plaws thiab zoo tshaj plaws rau kev rho tawm kub ntawm cov pob zeb. Cov txheej txheem no xav tau cyanide ntau dhau los txhim kho kev rov qab tau kub, tsim cov khib nyiab uas muaj cyanide hauv daim ntawv ntawm cov tailings thiab dej. Cyanide dawb, cov khoom tseem ceeb hauv cov txheej txheem metallurgical, suav tias yog hom cyanide lom tshaj plaws vim nws tuaj yeem ua rau muaj kev phom sij txawm tias muaj cov concentration tsawg. Lwm hom cyanide tuaj yeem yooj yim yaj mus ua cyanide dawb hauv qab cov xwm txheej acidic.

Qhov Yuav Tsum Tau Kho Cyanide - muaj cov Tailings

Qhov kev txo qis ntawm cyanide hauv cov tailings mus rau qib tsis muaj teeb meem siv sijhawm ntev. Yog li ntawd, cov tailings uas muaj cyanide yuav tsum tau kho ua ntej tso tawm rau hauv ib puag ncig kom tsis txhob muaj kev cuam tshuam tsis zoo rau ib puag ncig tau txais. Kev rhuav tshem ntawm cyanide hauv cov tailings leaching kub yog ib qho ntawm cov teeb meem loj tshaj plaws uas cov chaw khawb kub ntsib hauv ob peb xyoos dhau los. Yog li ntawd, kev kho cyanide hauv tailings kom zoo yog qhov tsim nyog kom tsis txhob lossis txo qis cov teeb meem ib puag ncig thiab kev noj qab haus huv.

Cov txheej txheem kev kho mob uas twb muaj lawm rau Cyanide

Tau ntau xyoo los no, muaj ntau txoj kev siv tshuaj lom neeg, lub cev, thiab tshuaj lom neeg, nrog rau kev siv hluav taws xob los ua kom cov cyanide lwj thiab lwm txoj hauv kev los rhuav tshem lossis rov qab tau cov cyanide, tau tsim los kho cov tshuaj cyanide. Tam sim no, cov txheej txheem siv dav hauv kev tsim cov tshuaj cyanide lwj suav nrog cov txheej txheem INCO, cov txheej txheem alkaline chlorination, cov txheej txheem activated Carbon , cov txheej txheem ozonation, cov txheej txheem hydrogen peroxide oxidation, thiab kev rov qab tau cov hydrogen cyanide. Cov txheej txheem INCO thiab alkaline chlorination siv los tshem tawm cov cyanide uas muaj concentration siab tab sis tsis tuaj yeem rhuav tshem cov cyanide tag nrho. Cov pa roj carbon uas ua kom cov cyanide lwj tuaj yeem nqus thiab sib sau ua ke tab sis tsis tuaj yeem rhuav tshem nws. Cov txheej txheem ozonation thiab hydrogen peroxide oxidation siv los kho cov cyanide uas muaj concentration qis nrog cov pa phem tsawg dua, tab sis lawv kim heev. Kev rov qab tau cov hydrogen cyanide tuaj yeem txo cov ntsiab lus cyanide thiab cov nqi tab sis tsis ua raws li qhov yuav tsum tau ua rau cov tailings rov qab.

Backfilling Technology thiab Cyanide Tshem Tawm Kev Tshawb Fawb

Kev siv tshuab rov qab los ua kom tiav yog qhov kev xaiv zoo tshaj plaws rau cov chaw tsuas zeb kom tawg los ntawm cov teeb meem ntawm cov peev txheej, ib puag ncig, thiab kev nyab xeeb. Txawm li cas los xij, cov tshuaj lom neeg xws li cov khoom siv hlau seem thiab cov kuab tshuaj hauv kub - cov tailings leaching yuav tsum tau kho kom zoo ua ntej rov qab los tiv thaiv kev ua qias tuaj hauv av. Kev tshawb fawb txog kev tshem tawm cyanide tau tsom mus rau cov dej khib nyiab hauv kev lag luam. Kev tshawb fawb txog kev tshem tawm cyanide hauv kub - leaching tailings, suav nrog cov dej khib nyiab thiab tailings, tseem muaj tsawg. Cov khoom siv hauv cov pob zeb kub yog qhov nyuaj heev, thiab cov tshuaj lom neeg xws li cyanide, Activated Carbon hmoov, thiab hydrogen peroxide raug ntxiv rau hauv cov txheej txheem beneficiation, ua rau cov khoom siv tailings nyuaj dua. Feem ntau ntawm cov cyanide seem hauv tailings yog adsorbed heev rau ntawm qhov chaw ntawm cov pob zeb, thiab tsuas yog me me ntawm cov cyanide dawb thiab hydrolyzed complex cyanide tuaj yeem nkag mus rau hauv leachate. Yog li ntawd, nws yog qhov tsim nyog los tshawb nrhiav cov txheej txheem zoo dua rau kev tshem tawm cyanide.

Qhov nyuaj ntawm CN⁻ Decomposition thiab Kev Tshawb Fawb Yav Tom Ntej

Qhov kom zoo decomposition ntawm CN⁻ yog ib tug complex txheej txheem. Nws xav tau kev sib xyaw ua ke ntawm ntau txoj hauv kev los txhim kho kev kho mob kom zoo thiab xav txog kev kho mob kev lag luam. Siv cov kev sib xyaw ua ke kom tshem tawm cyanide yog ib qho kev cog lus rau kev tshawb fawb yav tom ntej.
