Yuav ua li cas yog Aluminium Extracted los ntawm Aluminium Oxide

Ua li casAluminium Extracted los ntawm Aluminium Oxide?

Aluminium yog ib qho ntawm cov hlau uas siv ntau tshaj plaws thoob plaws ntiaj teb, thiab nws tsis muaj qhov xav tsis thoob vim li cas: nws muaj ntau yam, hnav, thiab ruaj khov. Tab sis li cas yog txhuas tau muab rho tawm los ntawm nws lub xeev raw, aluminium oxide? Cov txheej txheem no yog hu ua txheej txheem Bayer, muaj npe tom qab Austrian chemist Karl Josef Bayer, uas xub tsim nws hauv 1888.

Kauj Ruam 1: Mining

Thawj kauj ruam hauv kev rho tawm aluminium los ntawm nws lub xeev nyoos yog mine aluminium oxide los ntawm lub ntiaj teb. Qhov no suav nrog kev siv cov tshuab hnyav thiab cov khoom tawg los rhuav tshem lub ntiaj teb thiab rho tawm cov ntxhia.

Kauj Ruam 2: Npaj cov ore

Ib zaug lubaluminium oxidetau muab rho tawm, nws yog av rau hauv cov hmoov zoo thiab ces tov nrog sodium hydroxide nyob rau hauv loj hlau vats. Cov sodium hydroxide dissolves aluminium oxide, tawm hauv qab impurities thiab tsim cov hmoov dawb hu ua alumina.

Kauj Ruam 3: Smelting

Cov kauj ruam tom ntej yog smelt lub alumina rau hauv txhuas. Qhov no suav nrog melting alumina nyob rau hauv lub cub tawg loj ntawm qhov kub thiab txias uas siv cov hluav taws xob muaj zog. Raws li cov alumina melts, nws sib cais ua ob txheej: lub hnyav aluminium dab dej mus rau hauv qab, thaum lub lighter impurities ntab mus rau sab saum toj thiab yuav skimmed tawm.

Kauj Ruam 4: Refining

Cov kauj ruam kawg hauv kev rho tawm aluminium yog refining cov hlau. Qhov no suav nrog tshem tawm cov impurities seem thiab ntxiv lwm cov hlau thiab alloys kom muab cov txhuas zoo, xws li lub zog thiab kav ntev. Cov txheej txheem no tseem tuaj yeem koom nrog kev tsim thiab tsim cov txhuas rau hauv ntau yam khoom, xws li nplooj ntawv, raj, thiab daim hlau.

Niaj hnub nimno txoj kev thiab innovation nyob rau hauv lubaluminiumcov txheej txheem rho tawm tau ua kom nws ua tau zoo dua thiab zoo ib puag ncig. Piv txwv li, kev rov ua dua tshiab ntawm cov khoom siv txhuas xws li cov kaus poom thiab cov khoom siv hauv tsheb tuaj yeem txuag tau txog li 95% ntawm lub zog uas yuav tsum tau tsim cov txhuas los ntawm cov khoom siv raw.

Txhawm rau kom ua tiav, kev rho tawm ntawm txhuas los ntawm nws lub xeev nyoos suav nrog kev mining rau txhuas oxide, npaj cov ore los ntawm cov txheej txheem Bayer, smelting alumina rau hauv txhuas los ntawm lub qhov cub kub kub, thiab ua kom zoo dua cov hlau siv rau hauv ntau daim ntawv thov. Nrog rau kev tsim kho tshiab txuas ntxiv thiab kev nce qib hauv kev lag luam ntawm aluminium extraction, peb tuaj yeem cia siab tias yuav pom ntau txoj hauv kev ua tau zoo thiab ruaj khov nyob rau xyoo tom ntej.
