Yuav ua li cas yog aluminium pellets mined?
May 04, 2024| Aluminium pellet mining feem ntau yog ua los ntawm kev ua haujlwm mining hauv mines. Hauv qab no yog cov txheej txheem mining ntawm aluminium pellets:
1. Kev tshawb nrhiav pob zeb: Ua ntej, nws yog ib qho tsim nyog yuav tsum tshawb xyuas qhov muaj peev xwm aluminium pellet mining cheeb tsam los txiav txim qhov chaw tshwj xeeb thiab nplai ntawm thaj chaw mining. Qhov no suav nrog kev tshawb nrhiav geological, tshawb nrhiav geochemical, thiab tshawb nrhiav geophysical.
2. Ore mining: Tom qab lub mining cheeb tsam tau txiav txim siab, cov kauj ruam tom ntej yog mine lub ore. Muaj ob txoj hauv kev tsuas yog: qhib-qhov mining thiab underground mining. Qhib-qhov mining yog nthuav tawm cov ore deposit rau hauv av thiab siv txoj kev xws li blasting los khawb tawm cov ore; underground mining yog thauj cov ore tawm hauv av los ntawm underground tunnels.
3. Ore crushing: Cov mined ore yog crushed kom nws yooj yim rau refine aluminium pellets tom qab.
4. Refining aluminium pellets: Lub crushed ore yog smelted kom rho tawm txhuas pellets. Muaj ob txoj hauv kev tseem ceeb ntawm smelting: alumina smelting thiab electrolytic smelting. Cov qub yog oxidize cov ore thiab tom qab ntawd hnov mob nrog cov pa roj carbon monoxide los tsim cov hlau txhuas; tom kawg yog kom yaj cov ore nyob rau hauv ib tug molten electrolyte thiab extract metallic aluminium los ntawm ib tug electrolytic txheej txheem.
5. Refining: Cov khoom siv aluminium extracted yog refined kom tshem tawm impurities thiab txhim kho purity kom tau raws li qhov yuav tsum tau ntawm industrial ntau lawm.
6. Daim ntawv thov ntawm aluminium particles: Thaum kawg, cov khoom txhuas uas tau raug mined, rho tawm thiab ua kom zoo tuaj yeem siv rau hauv ntau yam kev lag luam thiab kev tsim khoom, xws li aerospace, tsheb tsim, khoom siv hauv tsev, thiab lwm yam.
Feem ntau, aluminium particle mining yog txheej txheem engineering uas yuav tsum tau muaj kev txhawb nqa ntawm ntau yam txuj ci thiab khoom siv. Nyob rau tib lub sijhawm, nws tseem yuav tsum ua raws li cov cai tswjfwm ib puag ncig thiab cov cai tswjfwm, tiv thaiv ib puag ncig mining, thiab ua tiav kev tsim kho kom ruaj khov.
