Silicon Hlauyog ib qho tseem ceeb me me ntais ntawv, dav siv nyob rau hauv ntau daim teb xws li hlau thiab hlau, alloy, photovoltaic thiab lwm yam. Cov txheej txheem ntau lawm ntawm silicon hlau feem ntau suav nrog peb cov kauj ruam tseem ceeb: ore Hnav ris tsho, smelting thiab refining. Nrog kev txhim kho kev kawm txuas ntxiv ntawm kev tshawb fawb thiab thev naus laus zis, kev tsim khoom ntawm silicon hlau tau txuas ntxiv nrog lub hom phiaj ntawm kev ua kom dawb huv thiab tawm los.

Cov Nyiaj Tau Los
Lub ntsiab ore ntawm silicon hlau yog quartzite muaj cov ntsiab lus silica siab uas tuaj yeem ncav cuag 95%. Cov neeg tau txais txiaj ntsig yog hais txog kev sib cais ntawm cov zaub mov muaj txiaj ntsig los ntawm cov ore nyoos thiab tshem tawm ntawm impurities los ntawm lawv. Cov txheej txheem tau txais txiaj ntsig tau muab faib ua ob hom: qhuav thiab ntub dej. Cov txiaj ntsig qhuav feem xyuam siv txoj kev siv lub cev yooj yim rau kev sib cais, xws li sib txawv hauv cov xim thiab ntom ntom ntom. Lub sijhawm so ntub dej, ntawm qhov tod tes, yuav tsum muaj kev sib nrauj lossis cov txheej txheem flotation rau kev siv cov zaub mov muaj txiaj ntsig.
smelting theem
SMELING yog ib cov txheej txheem uas cov ore tau txais los ntawm cov txiaj ntsig tau raug rau cov kev siv cua sov thiab tshuaj lom neeg kom tau cov hlau silicon. Cov txheej txheem smelting feem ntau yog hluav taws xob rauv smelting. Kev ua kom sov nrog cov hluav taws xob cuam tshuam nrog kev txo qis ntawm silica hauv quartz ores rau cov hlau ua silicon los ntawm kev siv hluav taws xob. Cov txheej txheem smelting cuam tshuam nrog cua sov cua sov, yog li cov khoom siv smelting yuav tsum muaj kev tiv thaiv kub. Cov txheej txheem smelting tseem ua rau muaj cov pa roj carbon dioxide ntau thiab cov leej txiv leej mos thiab lwm yam roj teeb meem, uas yuav tsum tau kho thiab tso tawm.
Refining Theem
Refining hais txog qhov ua kom huv ntxiv ntawm smelted silicon hlau kom tshem tawm impurities. Cov hau kev uas siv tau siv hauv cov txheej txheem ua kom zoo yog nitric acid leaching thiab cov kuab kev rho tawm. Nitric acid leaching txoj kev yog siv nitric acid los kho silicon hlau thiab tshem tawm impurities. Cov kuab tshuaj rho tawm yog siv cov kuab tshuaj solubility, thiab tom qab ntawd los ntawm kev rho tawm kom cais cov impurities. Cov txheej txheem ua kom zoo dua tseem yuav tsum tau tswj hwm qhov ntsuas kub thiab cov kuab tshuaj kom ntseeg tau cov nyhuv kho thiab khoom zoo.
Cov txheej txheem ntau lawm ntawm cov silicon yuav muaj qee qhov teeb meem ib puag ncig. Nws cov txheej txheem tsim khoom tsim ntau npaum li cas ntawm sluag thiab dej khib nyiab, uas yuav tsum tau kho thiab rov ua raws li cov neeg tsim khoom los txo qhov kev tsis zoo rau ib puag ncig.
