1. Introduction
Hauv kev lag luam khawb kub, kev siv Cyanide leaching yog ib txoj kev siv dav dav rau kev rho kub ntawm cov pob zeb. Txawm li cas los xij, kev siv Sodium cyanide , uas yog ib yam tshuaj lom heev, tsis yog tsuas yog ua rau muaj kev pheej hmoo rau ib puag ncig thiab kev nyab xeeb xwb tab sis kuj ua rau muaj nqi siab. Kev txo qis kev siv Sodium Cyanide hauv cov nroj tsuag cyanide Carbon -in-pulp tau dhau los ua ib txoj haujlwm ceev ceev los txhim kho kev lag luam zoo thiab kev phooj ywg ib puag ncig ntawm cov txheej txheem tsim khoom. Tsab xov xwm no nthuav qhia cov txiaj ntsig ntawm kev sim tsim khoom uas tsom mus rau kev txo qis kev siv sodium cyanide hauv cov nroj tsuag cyanide carbon-in-pulp.
2. Keeb kwm ntawm qhov teeb meem
Kev noj ntau ntawm sodium cyanide hauv cyanide carbon-in-pulp nroj tsuag yog vim muaj ntau yam. Ua ntej, muaj ntau yam impurities hauv cov ore, xws li tooj liab, zinc, thiab hlau, tuaj yeem hnov mob nrog cyanide, uas ua rau kev noj ntau ntawm sodium cyanide. Qhov thib ob, kev tswj tsis raug ntawm leaching tej yam kev mob, xws li pH tus nqi, qhov kub thiab txias, thiab aeration tus nqi, kuj tuaj yeem ua rau nce sodium cyanide noj. Tsis tas li ntawd, qhov tsis muaj peev xwm ntawm cov khoom siv leaching thiab cov txheej txheem rov ua dua ntawm cov tshuaj cyanide tuaj yeem ua rau qhov teeb meem no hnyav dua. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau ua qhov kev tshawb fawb tob thiab tshawb nrhiav kom pom cov kev ntsuas zoo los txo cov kev siv sodium cyanide.
3. Kev Tshawb Fawb
3.1 Ore Characterization
Thawj kauj ruam ntawm kev tshawb fawb yog ua kom paub meej cov yam ntxwv ntawm cov ore siv nyob rau hauv cyanide carbon-hauv-pulp cog. Cov tshuaj muaj pes tsawg leeg, mineralogy, thiab particle loj faib ntawm cov ore tau soj ntsuam. Cov ntaub ntawv no yog qhov tseem ceeb rau kev nkag siab txog qhov muaj peev xwm tshwm sim ntawm cov khoom siv ore thiab sodium cyanide thiab tsim cov tswv yim tsim nyog los txo cov kev siv sodium cyanide.
3.2 Optimization ntawm Leaching Conditions
Ib qho kev sim ua tau ua tiav los ua kom zoo dua qhov kev ua haujlwm leaching. Cov teebmeem ntawm pH tus nqi, qhov kub thiab txias, tus nqi aeration, thiab lub sijhawm leaching ntawm sodium cyanide noj thiab kub rho tawm tus nqi tau tshawb xyuas. Cov kev sib txawv ntawm cov kev ntsuas no tau raug sim, thiab qhov kev pom zoo tau txiav txim siab los ntawm kev ntsuam xyuas dav.
3.3 Pretreatment ntawm Ore
Txhawm rau txo qhov tsis zoo ntawm impurities nyob rau hauv cov ore ntawm sodium cyanide noj, pretreatment txoj kev tau tshawb nrhiav. Ob txoj kev pretreatment tseem ceeb, uas yog flotation thiab roasting, tau sim. Txoj kev flotation tsom kom cais cov khoom muaj txiaj ntsig los ntawm cov impurities, thaum txoj kev roasting tau siv los oxidize cov zaub mov sulfide thiab tshem tawm qee qhov impurities uas tuaj yeem haus cyanide.
3.4 Txhim kho Cyanide Recycling System
Kev ua haujlwm ntawm cyanide recycling system ncaj qha cuam tshuam rau kev noj sodium cyanide. Hauv qhov kev tshawb fawb no, kev txhim kho tau ua rau cyanide recycling system. Cov thev naus laus zis tshiab thiab cov cuab yeej siv tau raug qhia los txhim kho tus nqi rov qab ntawm cyanide los ntawm tailings thiab leaching tov. Tsis tas li ntawd, qhov zoo ntawm cov tshuaj siv tshuaj cyanide tau ua tib zoo saib xyuas thiab kho kom ntseeg tau tias nws rov siv tau zoo.
4. Ntsiab Lus thiab Kev Sib Tham
4.1 Cov teebmeem ntawm Leaching Condition Optimization
Kev ua kom zoo ntawm leaching tej yam kev mob ua tiav cov txiaj ntsig zoo kawg li. Los ntawm kev kho tus nqi pH mus rau qhov tsim nyog (kwv yees li 10 - 11), nce qhov kub ntawm 30 - 35 ° C, thiab tswj cov aeration tus nqi ntawm 0.5 - 1.0 L / min, sodium cyanide noj tau txo qis. Nyob rau tib lub sijhawm, tus nqi rho tawm kub tseem nyob ruaj khov lossis txawm tias nce me ntsis. Cov txiaj ntsig no tau qhia tias kev tswj xyuas kom raug ntawm cov kab mob leaching tuaj yeem txhawb cov tshuaj tiv thaiv ntawm kub thiab cyanide thaum txo qis kev noj cov tshuaj sodium cyanide.
4.2 Cov txiaj ntsig ntawm Ore Pretreatment
Cov txheej txheem ore pretreatment kuj pom muaj txiaj ntsig zoo. Lub flotation pretreatment zoo cais qee qhov impurities, xws li tooj liab thiab zinc minerals, los ntawm cov ore. Yog li ntawd, kev siv sodium cyanide thaum lub sij hawm tom qab leaching txheej txheem tau txo los ntawm 20%. Lub roasting pretreatment, txawm tias ntau zog - siv zog, kuj zoo heev. Tom qab roasting, sulfide minerals nyob rau hauv lub ore tau oxidized, thiab kev noj ntawm sodium cyanide txo los ntawm kwv yees li 30%. Txawm li cas los xij, txoj kev xaiv ntawm pretreatment yuav tsum yog raws li cov yam ntxwv tshwj xeeb ntawm cov ore thiab tag nrho kev lag luam thiab ib puag ncig kev xav ntawm cov nroj tsuag.
4.3 Txhim kho Cyanide Recycling System
Kev txhim kho ntawm cyanide recycling system tau nce qhov rov qab ntawm cyanide. Cov thev naus laus zis tshiab thiab cov cuab yeej siv tau ua kom rov qab tau tus nqi ntawm cyanide los ntawm cov tailings kom nce los ntawm qhov qub 60% mus rau ntau dua 80%, thiab qhov zoo ntawm cov tshuaj siv tshuaj cyanide kuj tau txhim kho. Qhov kev txhim kho no tsis tsuas yog txo qis cov sodium cyanide tshiab uas xav tau rau kev tsim khoom, tab sis kuj txo cov kev cuam tshuam ib puag ncig ntawm cyanide paug.
5. Cov lus xaus
Los ntawm qhov kev sim ntau lawm no, ntau qhov kev ntsuas tau pom zoo los txo qis sodium cyanide noj hauv cyanide carbon-hauv-pulp cog. Kev ua kom zoo rau cov dej leaching, pretreating cov ore, thiab txhim kho cov cyanide recycling system tuaj yeem ua rau txo qis sodium cyanide noj. Cov kev ntsuas no tuaj yeem tsis tsuas yog txo cov nqi tsim khoom tab sis kuj txhim kho kev ua haujlwm ib puag ncig ntawm cov nroj tsuag. Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias kev siv cov kev ntsuas no yuav tsum tau ua tib zoo soj ntsuam raws li qhov xwm txheej tiag tiag ntawm txhua tsob nroj, suav nrog cov khoom xws li cov khoom siv ore, kev tsim khoom, thiab kev lag luam muaj peev xwm. Kev tshawb fawb yav tom ntej tuaj yeem tsom mus rau kev txhim kho kev ua tau zoo ntawm cov txheej txheem no thiab tshawb nrhiav cov thev naus laus zis tshiab kom ua tiav qhov txo qis ntawm sodium cyanide noj hauv cov txheej txheem cyanide carbon-in-pulp.
