Daim ntawv thov ntawm All-Slime Cyanidation Carbon-in-Pulp Kub Extraction txheej txheem hauv Suav teb

Introduction

Hauv kev khawb kub thiab rho tawm, cov txheej txheem All-slime cyanidation Carbon -in-pulp (CIP) tau tshwm sim ua ib txoj hauv kev tseem ceeb. Cov txheej txheem no muaj txiaj ntsig zoo rau kev kho cov pob zeb kub uas muaj cov av nplaum ntau thiab cov khoom me me. Hauv Suav teb, nrog nws cov peev txheej kub nplua nuj thiab kev thov kub ntau zuj zus, cov txheej txheem All-slime cyanidation CIP tau pom kev siv dav dav, ua lub luag haujlwm tseem ceeb hauv kev lag luam khawb kub hauv tebchaws.

Cov ntsiab cai ntawm All-Slime Cyanidation Carbon-in-Pulp Process

Cov txheej txheem Cyanidation CIP tag nrho yog kev sib xyaw ua ke ntawm ob kauj ruam tseem ceeb: Cyanidation leaching thiab carbon-in-pulp adsorption.

Cyanidation Leaching

Cyanidation leaching yog lub hauv paus ntawm cov txheej txheem. Cov hlau kub, tom qab raug tsoo, sib tsoo, thiab pulped, raug sib xyaw nrog cov kua cyanide . Nyob rau hauv cov xwm txheej tsim nyog ntawm pH, kub, thiab cov pa oxygen, kub hauv cov hlau reacts nrog cyanide ions los tsim cov kub cyanide sib xyaw ua ke. Cov tshuaj tiv thaiv tuaj yeem hais yooj yim li:

Cov tshuaj tiv thaiv no tso cai rau kub kom yaj los ntawm cov ore matrix mus rau hauv cov tshuaj, cais nws los ntawm gangue minerals.

Carbon-hauv-Pulp Adsorption

Thaum kub yaj rau hauv cov kua cyanide, cov hmoov Activated Carbon yuav raug ntxiv ncaj qha rau hauv cov kua leaching. Cov hmoov activated carbon muaj peev xwm nqus tau cov kub cyanide complexes. Los ntawm cov txheej txheem adsorption lub cev thiab tshuaj, kub raug nqus rau ntawm qhov chaw ntawm cov hmoov activated carbon, ua kom sib cais kub ntawm cov kua cyanide. Cov kauj ruam no tshem tawm qhov xav tau cov txheej txheem sib cais khoom khov-kua hauv cov txheej txheem cyanidation ib txwm muaj, ua kom yooj yim rau cov txheej txheem rho tawm tag nrho.

Kev tsim kho keeb kwm ntawm All-Slime Cyanidation CIP txheej txheem hauv Suav teb

Tuam Tshoj txoj kev taug nrog tag nrho cov slime cyanidation CIP txheej txheem hnub rov qab ntau xyoo lawm.

Thaum Ntxov

Nyob rau nruab nrab xyoo pua 20th, Tuam Tshoj txoj kev lag luam kub tsuas yog siv cov txheej txheem rho tawm kub ib txwm muaj , uas muaj kev txwv hauv kev tswj cov ores nyuaj. Raws li qhov kev thov rau kub nce ntxiv thiab cov khoom tso nyiaj kub nyuaj dua tau pom, muaj qhov xav tau ceev ceev los qhia cov thev naus laus zis rho tawm siab heev. Cov txheej txheem CIP cyanidation tag nrho tau maj mam qhia thiab kawm. Xyoo 1970 thiab 1980, kev tshawb fawb thawj zaug thiab kev sim ua qauv tau ua tiav hauv qee qhov chaw kub. Piv txwv li, hauv qee qhov chaw kub hauv xeev Heilongjiang, tau sim siv cov txheej txheem no los kho cov ores kub hauv zos, uas tau tso lub hauv paus rau nws daim ntawv thov loj yav tom ntej.

Kev nthuav dav thiab kev loj hlob

Nyob rau hauv lub xyoo tom ntej no, nrog kev nruam kev thev naus laus zis thiab kev txhim kho, tag nrho cov slime cyanidation CIP txheej txheem tau pib nthuav dav thiab siv thoob plaws hauv lub tebchaws. Hauv xyoo 1990 thiab 2000s, ntau lub pob zeb kub hauv Henan, Shandong, Jilin, thiab lwm lub xeev tau tsim cov kab ntau lawm cyanidation CIP. Cov mines no txuas ntxiv txhim kho cov txheej txheem tsis tu ncua, txhim kho cov cuab yeej siv tau zoo, thiab pab pawg kws tshaj lij kev cob qhia. Yog li ntawd, tus nqi rov qab ntawm kub maj mam nce, thiab cov nqi tsim khoom tau tswj tau zoo. Thaum kawg ntawm lub xyoo pua 20th, tag nrho cov slime cyanidation CIP txheej txheem tau dhau los ua ib qho ntawm cov txheej txheem kub rho tawm hauv Suav teb, suav nrog feem ntau ntawm lub teb chaws kub ntau lawm.
