Lub luag haujlwm ntawm cov khoom siv tshuaj tiv thaiv hauv Extracting Electrolytic Copper

Xi'an Maike Hlau International Group Co., Ltd. (tom qab no hu ua "Maike Group"), nrhiav tau nyob rau hauv 1993, yog ib tug tseem ceeb hlau thiab mineral tub luam nyob rau hauv Tuam Tshoj, thiab tam sim no tau lees paub tias yog ib tug thawj coj nyob rau hauv Suav kev lag luam. Nws muaj ntau tshaj 20 lub tuam txhab lag luam thiab chaw ua haujlwm hauv Suav teb Mainland, Hong Kong, Singapore, London thiab lwm qhov chaw, tsim kom muaj kev lag luam thoob ntiaj teb uas npog ntau tshaj 20 lub teb chaws thiab cheeb tsam ntawm rau lub teb chaws hauv ntiaj teb.

 

 

Thaum Lub Ob Hlis 2015, Meike Group thiab ACHIEVE CHEM tau sib koom ua qhov kev tshawb fawb tshwj xeeb ntawm "Yuav ua li cas Electrolytic Copper Refined" los tshawb txog kev tsim cov hlau tsis muaj hlau.

 

 

   

 

Cov tooj liab ore muab zais rau hauv cov roob tob muaj ntau hom, txawm tias ci ntsa iab nrog kub lossis xim, nrog rau qhov pom loj heev tab sis qhov tseeb thiab purity tsawg heev. Tom qab sib sib zog nqus excavation, tooj liab ore raug crushed,

 

Cov chunks loj ntawm tooj liab tau muab faib ua ntau txhiab lub pob zeb crushed. Txhawm rau ua kom zoo dua qub, me me ntawm tooj liab ore raug xa mus rau lub pob zeb, hauv av rau hauv cov hmoov, thiab raug flotation thiab ziab kom tau txais cov tooj liab zoo nrog cov ntsiab lus tooj liab (feem ntau) tsis pub tsawg dua 13 feem pua ​​​​rau tooj liab. smelting. Ntawm txoj kev los ua electrolytic tooj liab, peb tau nkag mus rau hauv cov txheej txheem smelting ntawm no. Cov txheej txheem smelting los ua electrolytic tooj liab los ntawm tooj liab concentrate yog muab faib ua ob pawg: pyrometallurgy thiab hydrometallurgy.

 

 

Pyro smelting yog tsim los ntawm tooj liab monosulfide concentrate, thiab electrolytic tooj liab yog tsim los ntawm smelting, converting, pyro refining, electrolytic refining thiab lwm yam txuas.

 

Sulfur smelting (los ntawm tooj liab mloog zoo rau matte) feem ntau yog siv tooj liab mloog zoo los ua matte smelting, nrog rau lub hom phiaj ntawm oxidizing ib co hlau nyob rau hauv lub tooj liab concentrate, tshem tawm slag, thiab ua sulfuric acid los ntawm sulfur los tsim matte.

 

Matte tshuab (los ntawm matte rau crude tooj liab) ntxiv oxidizes thiab slags lub matte kom tshem tawm cov hlau thiab leej faj, ua cov tooj liab crude.

 

Pyro refining (los ntawm ncuav mog qab zib tooj liab mus rau anode tooj liab) ntxiv tshem tawm impurity ntsiab ntawm crude tooj liab los ntawm oxidation slagging los tsim anode tooj liab.

 

Electrolytic refining (los ntawm anode tooj liab mus rau electrolytic tooj liab) koom nrog cov kev taw qhia ntawm ncaj qha tam sim no, uas dissolves lub anode tooj liab thiab precipitates ntshiab tooj liab ntawm lub cathode. Cov impurities nkag mus rau hauv cov av nkos anode los yog electrolyte, ua tiav kev sib cais ntawm tooj liab thiab impurities thiab tsim electrolytic tooj liab.

 

 

Cov khoom siv tshuajFeem ntau siv rau pyrometallurgy ntawm tooj liab monosulfide suav nrog:

 

Rauv: siv los muab qhov kub thiab txias ib puag ncig thiab kub tooj liab sulfide ore rau melting point.

Lub tshuab cua txias: siv los txias thiab solidify cov khoom tom qab smelting.

Cov khoom siv lim: siv los cais cov khoom thiab cov theem ua kua thiab lim tawm cov khoom siv tooj liab monosulfide.

Oxygen mov system: siv los muab cov pa oxygen rau cov tshuaj tiv thaiv oxidation.

Cov khoom siv cua sov: Hluav taws xob rauv, roj rauv, thiab lwm yam, siv los ua kom sov cov tshuaj tiv thaiv.

 

Cov hauv qab no yog cov ncauj lus kom ntxaws txog kev ua haujlwm:

 

Ore npaj: tsoo tooj liab sulfide ore rau hauv qhov loj me me.

Ntxiv rau qhov cub: Muab cov ore tso rau hauv lub qhov cub ua ntej. Koj tuaj yeem ntxiv qee cov kuab tshuaj los yog cov fluxes raws li xav tau, xws li coke lossis alkali hlau sib txuas.

Cua sov: Pib lubcua sov circulatorkom muaj cua sov txaus kom coj cov ore mus rau nws qhov chaw melting. Thoob plaws hauv tag nrho cov txheej txheem, tswj cov cua kub thiab lub sij hawm kom paub meej txaus cov tshuaj tiv thaiv.

Cov tshuaj tiv thaiv oxidation: Txhaj cov pa oxygen rau hauv qhov cub kom oxidize tooj liab sulfide ore. Oxygen yuav hnov ​​​​mob nrog sulfides los tsim cov pa roj xws li SO2 thiab sulfate.

Sau SO2 roj: Sau SO2 roj los ntawm cov khoom siv cua txias thiab cov tshuab pom, thiab txheej txheem thiab rov qab los.

Cov khoom sib cais: Siv lubstainless hlau distillation systemtshem tawm cov khoom txias thiab solidified los ntawm lub cub tawg, thiab tom qab ntawd ua cov kua-kua sib cais los ntawm cov khoom siv lim kom tau cov khoom siv tooj liab monosulfide.

Kev kho cov khoom: ntxiv kev kho mob ntawm tooj liab monosulfide cov khoom, xws li ntxuav, ziab thiab refining, txhim kho cov purity ntawm cov khoom.

Kev kho roj: Ua cov roj av kho cov roj SO2 khaws cia, xws li kev ua kom huv, nqus, lossis hloov dua siab tshiab, kom txo tau qhov cuam tshuam rau ib puag ncig.

 

Cov smelting ntub dej yuav tsum tau ua ntej oxidation los yog sulfuric acid roasting ntawm tooj liab cov zaub mov los hloov lawv mus rau hauv lub xeev soluble, ua raws li leaching, extraction, purification, thiab electrowinning kom rho electrolytic tooj liab.

 

Cov txheej txheem ntawm pyrometallurgical tooj liab smelting yog txawv los ntawm hydrometallurgical tooj liab smelting, tab sis vim muaj kev txwv ntawm raw cov ntaub ntawv nyob rau hauv lub tam sim no technological theem, pyrometallurgical tooj liab smelting tseem yog lub ntsiab nyob rau theem no.

 

Ib qho tooj liab ore tau dhau los ntawm kev hloov pauv hloov tshiab ntawm 1.0 mus rau 2.0, los ntawm kev ua tiav mus rau kev tawg, los ntawm kev tawg mus rau recombination, los ntawm recombination mus rau deconstruction, thiab los ntawm deconstruction mus rau iteration, transforming rau hauv electrolytic tooj liab. daim ntawv.
