Kev lag luam silicon smelting yuav tsum nruj tswj hwm cov khoom siv raw. Silica thiab carbonaceous txo cov neeg ua haujlwm yog ob yam khoom siv tseem ceeb hauv cov txheej txheem no. Cov kev qhia tshwj xeeb uas tsim nyog rau cov khoom siv raw yog nruj vim qhov yuav tsum tau nruj ntawm cov ntsiab lus ntawm txhuas, calcium, thiab hlau nyob rau hauv qhov tshwm sim muaj silicon. Cov silica siv yuav tsum muaj SiO2 cov ntsiab lus ntau dua 99.0%, nrog Al2O3 tsawg dua 0.3%, Fe2O3 tsawg dua 0.15%, CaO tsawg dua {{11 }}.2%, thiab MgO tsawg dua 0.15%. Tsis tas li ntawd, qhov loj me me yuav tsum poob hauv qhov ntau ntawm 15-80mm.
Cov carbonaceous txo tus neeg sawv cev siv yuav tsum tau ua raws li qee yam kev cai. Nws yuav tsum muaj cov ntsiab lus siab ruaj khov, cov hmoov tshauv tsawg, thiab cov tshuaj ua haujlwm zoo. Feem ntau, cov hmoov tshauv qis roj av coke lossis pitch coke yog siv los ua tus neeg sawv cev txo qis. Txawm li cas los xij, cov ntaub ntawv no muaj qhov tsis muaj zog thiab tsis muaj peev xwm tiv thaiv tsis zoo, yuav tsum tau ntxiv cov charcoal lossis ntoo blocks uas muaj cov hmoov tshauv tsawg, muaj zog tiv taus, thiab muaj peev xwm tiv thaiv tau. Ib qho me me ntawm cov hmoov tshauv tsawg-tsawg bituminous thee kuj ntxiv rau sinter tus nqi.
Txawm hais tias qhov sib ntxiv ntawm cov hluav taws xob hluav taws xob lossis cov khoom siv ntoo yog qhov zoo, kev siv cov khoom siv ntau dhau yuav ua rau tus nqi ntawm cov khoom thiab ua rau cov khoom siv hluav taws xob tsis zoo. Qhov no tuaj yeem ua rau muaj teeb meem hauv tapping thiab lwm yam teeb meem. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tsum tau siv cov khoom tsim nyog ntawm txhua yam khoom los xyuas kom muaj txiaj ntsig zoo, muaj txiaj ntsig zoo rau kev lag luam silicon smelting.
