Cov txheej txheem pyrometallurgical tooj liab smelting hloov tooj liab mloog zoo rau hauv siab -purity cathode tooj liab los ntawm kev kub siab - ua haujlwm kub. Txoj kev no dominates sulfide ore ua thoob ntiaj teb vim hais tias nws muab kev ntseeg siab rov qab tus nqi siab tshaj 95% thiab tsim 99.99% ntshiab tooj liab npaj rau kev lag luam siv. PRS tshwj xeeb hauv cov khoom siv hluav taws kub smelting thiab muab cov kev daws teeb meem tiav raws li koj cov qib siab thiab cov nroj tsuag xav tau.
1. Kev sib tsoo thiab kev faib tawm
Copper extraction pib nrog ore sib tsoo. Hlau sib tsoo pob hauv ib lub pob zeb loj txo cov pob zeb crushed rau cov khoom zoo. Lub tshuab tso tawm hla dhau ib lub sieve-zoo li txoj siv sia conveyor uas cais cov khoom me me rau theem tom ntej thaum xa rov qab cov khoom loj rau regrinding. Qhov no kaw -circuit system ua kom pom kev tso tawm ntawm tooj liab minerals ua ntej flotation.
2. Flotation los tsim Copper Concentrate
Cov neeg ua hauj lwm ntxiv cov tshuaj rau hauv av ore kom encapsulate tooj liab minerals, ces sib tov nyob rau hauv frothing agents los tsim slurry. Cov slurry nkag mus rau hauv cov hlwb flotation qhov twg cua txhaj tshuaj ua npuas uas txuas rau tooj liab thiab nqa mus rau saum npoo. Cov neeg ua haujlwm skim tawm cov froth, lim nws, thiab tau txais kev mloog zoo nrog 25-30% tooj liab cov ntsiab lus. Railcars thauj cov concentrate no mus rau smelter.
3. Thawj theem Smelting: Matte ntau lawm nrog Silica Flux
Nyob rau ntawm lub refinery, cov neeg ua haujlwm xa cov kev xav mus rau ib qho chaw loj loj thiab txheej nrog silica xuab zeb, uas ua raws li cov dej ntws thiab cov impurity tshem tawm. Hauv qhov kub siab - qhov cub kub, tus nqi melts. Silica ua ke nrog hlau thiab lwm yam impurities los tsim slag uas ntab saum toj, thaum tooj liab - nplua nuj matte dab dej thiab mus txog kwv yees li 60% purity. Lub slag absorbs gangue cov ntaub ntawv zoo.
4. Qhov thib ob Smelting theem: Blister tooj liab tsim
Cranes ncuav lub molten matte rau hauv lub qhov cub thib ob. Cov txheej txheem rov ua dua nrog oxidation ntxiv kom hlawv tawm cov sulfur thiab hlau ntxiv. Cov kauj ruam no nce tooj liab purity mus rau 98%, ua blister tooj liab. Cov neeg khiav dej num pov tseg cov silica slag siv rau hauv ib lub pob zeb pov tseg sab nraum zoov uas nws txias thiab sib xyaw nrog hauv av.
5. Qhov thib peb smelting theem: hluav taws Refining rau Anode tooj liab
Lub molten tooj liab txav mus rau qhov cub thib peb rau qhov kawg hluav taws refining. Ntxiv impurity tshem tawm nce purity mus rau 99.4%. Lub refined tooj liab ntws mus rau hauv lub pwm tig thiab nrum rau hauv cov duab plaub anode daim hlau uas ua haujlwm zoo li electrodes hauv electrolytic refining.
6. Anode Casting thiab txias
Raws li cov tooj liab txias nyob rau hauv pwm, sprayers siv dej kom ceev solidification. Thaum hardened, hydraulic cylinders eject lub anode daim hlau. Lub conveyor system clamps thiab ntxuav lawv. Nroj tsuag ua ntej-coat pwm uas tsis yog- cov tshuaj nplaum kom ntseeg tau yooj yim tso tawm. Tshaj npoo ntawm daim hlau tso cai rau cov tshuab nqa thiab tuav lawv yam xyuam xim.
7. Electrolytic Refining rau Cathode Copper
Cov tsheb thauj khoom thauj cov anode daim hlau ntau pua kilometers mus rau qhov kawg refinery. Cov neeg ua haujlwm muab lawv tso rau hauv lub tank txuas ntxiv electrolytic uas muaj tooj liab sulfate electrolyte. Cov hluav taws xob tam sim no ntws los ntawm cov tso tsheb hlau luam, dissolving tooj liab los ntawm cov anodes thiab tso nws mus rau cov pib cathodes. Cov kauj ruam kawg no tshem tawm cov impurities seem thiab tsim cov tooj liab cathode nrog 99.99% purity.
Cov txheej txheem pyrometallurgical tooj liab smelting no tuav sulfide concentrates zoo thiab integrates seamlessly nrog niaj hnub rauv technologies xws li flash smelting los yog converters nyob rau hauv loj -scale ua hauj lwm. Kev xaiv khoom siv ncaj qha cuam tshuam rau kev siv hluav taws xob, tus nqi rov qab, thiab kev tswj slag.
Cov qib sib txawv thiab qib impurity yuav tsum tau kho qhov cub ua kom haum, qib matte, thiab kev ua kom zoo dua qub. Kev xaiv khoom siv tsis raug tuaj yeem txo qis rov qab los yog nce nqi khiav haujlwm. PRS tshwj xeeb hauv hluav taws thiab hydrometallurgical tooj liab smelting khoom, nrog rau kev sib tsoo mills, flotation hlwb, smelting furnaces, converters, anode casting machines, thiab electrolytic tankhouses. Peb xa tag nrho cov kab tsim tsim, kev xaiv cov khoom siv meej, thiab kev ua kom zoo los pab koj lub smelter ua tau zoo dua purity, qis zog noj, thiab muaj zog kev lag luam. Hu rau PRS hnub no rau kev sib tham txog cov txheej txheem thiab cov khoom siv.
