Qhov zoo thiab qhov tsis zoo ntawm Sodium Cyanide hauv Kub Leaching

Hauv kev lag luam kub mining, cov txheej txheem ntawm kub rho tawm yog qhov tseem ceeb tshaj plaws. Sodium cyanide tau ntev lawm ib tug tseem ceeb reagent nyob rau hauv lub kub leaching txheej txheem. Kev nkag siab txog nws qhov zoo thiab qhov tsis zoo yog qhov tseem ceeb rau ob qho tib si miners thiab environmentalists, vim nws pab txiav txim siab paub txog nws txoj kev siv txuas ntxiv thiab tshawb nrhiav lwm txoj hauv kev.

1. Qhov zoo ntawm Sodium Cyanide hauv Kub Leaching

High Efficiency nyob rau hauv kub Dissolution

Ib qho tseem ceeb tshaj qhov zoo ntawm li ntawd

dum cyanide nyob rau hauv kub leaching yog nws high efficiency nyob rau hauv dissolving kub. Cyanide ions tsim kev ruaj khov nrog cov ions kub. Qhov no tso cai rau kev rho tawm ntawm kub los ntawm qib qis ores. Cov tshuaj tiv thaiv ntawm kub, oxygen, thiab sodium cyanide Nyob rau hauv ib qho kev daws aqueous tuaj yeem sawv cev raws li:

4Au + 8NaCN + O₂ + 2H₂O → 4Na[Au(CN)₂] + 4NaOH. Cov tshuaj tiv thaiv no ua rau muaj qhov ua tiav ntawm kev rho tawm ntawm kub, ua kom cov txiaj ntsig tau los ntawm cov mined ore.

Nqi - Ua tau zoo

Sodium cyanide yog tus nqi - zoo piv rau ntau lwm cov leaching agents. Nws cov txheej txheem ntau lawm yog qhov zoo - tsim, thiab nws tau yooj yim muaj nyob rau hauv ntau qhov ntau. Cov tuam txhab mining tuaj yeem yuav Sodium Cyanide ntawm tus nqi tsim nyog, uas yog qhov tseem ceeb rau kev tswj kom muaj txiaj ntsig zoo, tshwj xeeb tshaj yog thaum cuam tshuam nrog kev ua haujlwm loj. Tsis tas li ntawd, cov cuab yeej siv yooj yim uas yuav tsum tau ua rau cov txheej txheem cyanide leaching ntxiv txo cov nqi.

Compatibility nrog txawv Ore hom

Sodium cyanide tuaj yeem siv nrog ntau yam kub - bearing ores. Txawm hais tias cov ore yog dawb - milling los yog muaj complex sulfide minerals, cyanide leaching feem ntau yuav optimized rau extract kub. Qhov kev hloov pauv no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau ntau qhov kev lag luam mining thoob ntiaj teb, vim nws txo qhov kev xav tau ntawm cov nqi ore - cov txheej txheem kev ua haujlwm tshwj xeeb.

2. Qhov tsis zoo ntawm Sodium Cyanide hauv Kub Leaching

Kev Nyab Xeeb Ib puag ncig

Qhov tseem ceeb tshaj plaws drawback ntawm Sodium cyanide yog nws toxicity heev. Cyanide yog qhov ua rau tuag taus rau cov dej hauv dej, noog, thiab tsiaj txhu. Nyob rau hauv qhov xwm txheej ntawm cyanide nchuav ntawm qhov chaw mining, nws tuaj yeem ua rau cov dej nyob ze, ua rau cov ntses thiab lwm yam kab mob hauv dej tuag. Txawm tias me me ntawm cyanide hauv dej tuaj yeem cuam tshuam tag nrho ecosystems. Piv txwv li, cyanide tuaj yeem cuam tshuam kev ua haujlwm ntawm cytochrome c oxidase hauv hlwb, tiv thaiv kev siv cov pa oxygen hauv kev ua pa aerobic.

Cov kev cai nruj nruj

Vim nws cov tshuaj toxicity, kev siv sodium cyanide hauv cov mining kub yog ua raws li cov cai nruj. Cov tuam txhab lag luam mining yuav tsum tau nqis peev hauv cov txheej txheem tswj cov khib nyiab kom tsis txhob muaj cyanide nkag mus rau ib puag ncig. Lawv yuav tsum tau siv cov kev saib xyuas kom ntseeg tau tias qib cyanide hauv dej thiab huab cua nyob rau hauv qhov kev txwv. Cov kev cai tswj hwm no nce cov nqi khiav lag luam ntawm cov tuam txhab mining, vim lawv yuav tsum faib cov peev txheej kom ua raws li cov cai.

Kev phom sij rau cov neeg ua haujlwm

Cov neeg ua haujlwm koom nrog hauv cov txheej txheem kub leaching uas siv sodium cyanide muaj kev pheej hmoo ntawm kis. Kev nqus tau los yog tawv nqaij nrog cyanide tuaj yeem ua rau muaj teeb meem kev noj qab haus huv, nrog rau mob taub hau, kiv taub hau, xeev siab, thiab mob hnyav, tuag taus. Cov tuam txhab lag luam mining yuav tsum muaj kev cob qhia kev nyab xeeb thiab cov cuab yeej tiv thaiv tus kheej rau lawv cov neeg ua haujlwm kom txo qis cov kev pheej hmoo no. Txawm li cas los xij, kev xwm txheej tseem tuaj yeem tshwm sim, ua rau cov neeg ua haujlwm txoj sia nyob ntawm ceg txheem ntseeg.

Hauv kev xaus, sodium cyanide muaj qhov zoo sib xws ntawm kev ua tau zoo, tus nqi - kev ua tau zoo, thiab ore compatibility hauv cov txheej txheem kub leaching. Txawm li cas los xij, nws cov kev phom sij ib puag ncig, kev tswj hwm nruj, thiab kev pheej hmoo rau cov neeg ua haujlwm noj qab haus huv tsis tuaj yeem tsis quav ntsej. Raws li kev lag luam mining mus rau pem hauv ntej, yuav tsum muaj kev loj hlob ntxiv los tsim lwm txoj hauv kev leaching uas yog ob qho tib si ib puag ncig thiab kev lag luam, thaum tswj hwm cov qauv kev rho tawm zoo tam sim no ua tiav nrog sodium cyanide.
