Vim li cas Sodium Cyanide Siv dav hauv Kub Extraction?

Hauv kev rho kub , sodium cyanide yog ib qho tshuaj reagent tseem ceeb, ua lub luag haujlwm tseem ceeb hauv kev lag luam. Tab sis dab tsi ua rau nws tseem ceeb heev? Cia peb tshawb nrhiav cov laj thawj tom qab nws siv dav.

1. Tshuaj Reactivity

Qhov ua tau zoo ntawm Sodium cyanide hauv kev rho kub yog vim nws cov khoom siv tshuaj lom neeg tshwj xeeb. Kub, hauv nws daim ntawv ib txwm muaj, yog qhov tsis muaj zog thiab tsis yooj yim ua rau muaj kev cuam tshuam nrog feem ntau cov tshuaj. Txawm li cas los xij, thaum Sodium Cyanide raug qhia rau hauv cov txheej txheem rho tawm, nws ua rau muaj kev cuam tshuam nrog kub thaum muaj pa oxygen thiab dej los tsim cov khoom kub-cyanide uas yaj tau. Qhov kev cuam tshuam no hloov cov khoom kub uas tsis yaj tau mus rau hauv lub xeev yaj tau, uas ua rau yooj yim sib cais los ntawm cov hlau ore matrix. Lub peev xwm no los tsim cov khoom ruaj khov thiab yaj tau nrog kub yog qhov tseem ceeb hauv kev siv Sodium cyanide ntau hauv kev khawb kub.

2. Kev ua tau zoo thiab kev huv

Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev siv sodium cyanide hauv kev rho kub yog nws qhov ua tau zoo heev. Kev rho cyanide tuaj yeem ua tiav qib siab ntawm kev rov qab tau kub, feem ntau rho tawm txog li 90% lossis ntau dua ntawm cov kub uas muaj nyob hauv cov hlau, nyob ntawm cov yam ntxwv ntawm cov hlau. Piv rau qee lwm txoj kev rho tawm, xws li kev sib xyaw MERCURY , kev rho cyanide zoo dua hauv kev rho kub los ntawm ntau hom hlau, suav nrog cov hlau qib qis.

Ntxiv mus, cov kub-cyanide compound tsim thaum lub sij hawm leaching txheej txheem tuaj yeem ua tiav ntxiv kom tau txais cov kub purity siab. Los ntawm cov kauj ruam tom ntej xws li nag lossis daus nrog zinc lossis electrolysis, cov kub tuaj yeem rov qab los rau hauv lub xeev ntshiab, ua tau raws li cov kev xav tau zoo ntawm cov hniav nyiaj hniav kub, hluav taws xob, thiab kev lag luam peev.

3. Nqi - kev ua tau zoo

Los ntawm kev xav txog kev lag luam, sodium cyanide muab nqi - kev ua tau zoo. Txawm hais tias sodium cyanide nws tus kheej yog cov tshuaj lom, nws cov nqi tsim khoom thiab kev yuav khoom yog qhov tsim nyog piv rau lwm cov tshuaj reagents uas tuaj yeem siv rau kev rho tawm kub. Tsis tas li ntawd, cov txheej txheem cyanidation tau zoo - tsim thiab optimized ntau xyoo lawm. Cov kev tsim kho vaj tse thiab cov khoom siv uas yuav tsum tau ua rau cyanide leaching yog tus qauv, txo qhov kev xav tau ntawm kev siv tshuab kim, tshwj xeeb. Qhov no txhais tau hais tias cov tuam txhab mining tuaj yeem ua tiav cov txiaj ntsig kub rho tawm ntawm tus nqi qis rau ib chav tsev ntawm cov kub tsim, ua rau nws yog qhov kev xaiv zoo nkauj hauv kev lag luam kub sib tw.

4. Tsim kev tsim kho vaj tse thiab kev paub

Kev lag luam kub mining tau siv sodium cyanide rau kev rho tawm kub rau ntau tshaj ib puas xyoo. Yog li ntawd, muaj ib tug zoo-tsim infrastructure nyob ib ncig ntawm kev siv ntawm sodium cyanide. Cov tuam txhab mining tau nkag mus rau cov khoom lag luam txhim khu kev qha rau sodium cyanide, los ntawm kev tsim khoom mus rau kev thauj mus los thiab khaws cia.

Tsis tas li ntawd, mining engineers, cov kws tshaj lij, thiab cov neeg ua haujlwm paub zoo txog cov txheej txheem cyanidation. Lawv tau txais kev cob qhia hauv kev tuav cov sodium cyanide kom zoo, ua haujlwm ntawm cov khoom siv leaching, thiab tswj tag nrho cov txheej txheem rho tawm. Qhov kev paub thiab kev txawj ntse no ua rau nws yooj yim dua rau kev ua haujlwm mining los siv thiab tswj cov txheej txheem cyanidation, txo cov kev kawm nkhaus thiab cov kev pheej hmoo uas cuam tshuam nrog kev siv cov txheej txheem tshiab thiab tsis siv cov extraction.

5. Adaptability rau ntau hom ore

Sodium cyanide - raws li txoj kev rho tawm yog hloov tau mus rau ntau hom kub ore. Txawm hais tias nws yog dawb - milling ores qhov twg kub yog yooj yim tso tawm los ntawm lub tsev pob zeb, los yog ntau dua refractory ores uas yuav tsum tau ntxiv pretreatment cov kauj ruam, cyanide leaching yuav kho thiab optimized. Rau refractory ores, txoj kev xws li roasting, siab oxidation, los yog bio - oxidation tuaj yeem ua ke nrog cyanide leaching los rhuav tshem cov qauv ore thiab nthuav tawm cov kub rau cov tshuaj cyanide, ua kom muaj txiaj ntsig zoo. Qhov kev ua tau zoo no ua rau sodium cyanide yog qhov kev xaiv zoo tshaj plaws rau cov tuam txhab mining cuam tshuam nrog ntau hom ore deposits.

Txawm li cas los xij, nws tseem ceeb heev uas yuav tsum nco ntsoov tias thaum sodium cyanide muaj txiaj ntsig zoo hauv kev rho tawm kub, nws siv kuj ua rau muaj kev txhawj xeeb txog kev nyab xeeb thiab kev nyab xeeb vim nws cov tshuaj lom neeg siab. Raws li qhov tshwm sim, kev lag luam niaj hnub tshawb nrhiav thiab tsim lwm txoj hauv kev rho tawm thiab txhim kho cov txheej txheem kev nyab xeeb kom txo qis kev pheej hmoo cuam tshuam nrog kev siv sodium cyanide thaum tseem ua tau raws li kev thov thoob ntiaj teb rau kub.
