Tuam Tshoj yog lub teb chaws uas xav tau ntau tshaj plaws rau tooj liab.Nws qhov kev thov suav rau 45% ntawm qhov xav tau thoob ntiaj teb.Cov neeg tsim khoom siv tooj liab yog nyob hauv lub teb chaws Yelemees, Chile, Indonesia thiab Canada feem.Nws yuav siv sij hawm ntau tus neeg ua haujlwm kom rho tawm cov tooj liab kom zoo thiab nws xav tau ntau cov txheej txheem los kho nws, uas tseem ua rau muaj kev kub ntxhov ntau rau ib puag ncig.Txog tam sim no, cov mines tooj liab raug cuam tshuam los ntawm ntau yam, xws li kev tawm tsam ntawm kev tsis sib haum xeeb ntawm kev ua haujlwm hauv Chile thiab tsis muaj hluav taws xob hauv Zambia thiab Congo, uas tau txwv kev siv tooj liab.Ntau tus neeg ua haujlwm hauv Chile qhov loj tshaj plaws tooj liab mines nyob ze ntawm Cujkammata tooj liab mine, uas feem ntau suav rau ib feem kaum lossis peb feem kaum ntawm tus nqi tag nrho rau kev lag luam tooj liab extractive vim muaj kev phom sij ntau dua, yog li kev ua haujlwm hauv av mining raug nqi ntau dua.
Hauv kev tsim thiab tsim cov txheej txheem ntawm concentrator, txhawm rau ua kom muaj txiaj ntsig zoo tshaj plaws ntawm cov khoom siv tseem ceeb hauv cov ores xaiv thiab txo cov kev siv hluav taws xob ntawm cov concentrator kom ntau li ntau tau, kev cuam tshuam ib puag ncig thiab kev ua qias tuaj raug txo, thiab cov txiaj ntsig kev lag luam thiab kev sib raug zoo. ntawm cov concentrator yog nce Qhov kev xaiv ntawm crushing, sib tsoo, flotation thiab concentration khoom yog tshwj xeeb tshaj yog tseem ceeb.Kev sib tsoo, kev sib tsoo cov txheej txheem kev siv hluav taws xob thiab kev siv hlau tau suav rau ntau tshaj li ib nrab ntawm cov khoom tsim tawm, tshwj xeeb tshaj yog cov txheej txheem sib tsoo, kev siv zog ntawm ib chav nyob deb tshaj li cov txheej txheem crushing, suav txog ntau dua 85% ntawm tag nrho cov ntxhia crushing ua haujlwm, suav nrog kev xaiv tsa. cog ntawm 30% mus rau 60%.Yog li ntawd, kev siv cov txheej txheem crushing tshiab, kev xaiv cov khoom siv loj-loj crushing thiab lwm txoj hauv kev los ntxiv dag zog rau kev ua haujlwm crushing, txo cov ore noj ore loj, yog los txhim kho kev ua haujlwm ntawm crushing, txo tus nqi ntawm kev hnav khaub ncaws. txoj kev tseem ceeb, tab sis kuj tsim cov neeg tau txais txiaj ntsig yuav tsum ua raws thiab xav txog cov hauv paus ntsiab lus.
Cov txheej txheem crushing ntawm cov txheej txheem tsoos tsoos muaj qhov loj me me thiab nws nyuaj rau kev siv lub zog txuag txoj cai ntawm ntau crushing thiab sib tsoo tsawg.Cov txheej txheem nta yog: kev siv hluav taws xob siab, cov txheej txheem ntev.Feem ntau, kev ua haujlwm crushing yuav tsum tau siv ob lossis ntau daim ntawm cov khoom tawg kom tau txais cov khoom lag luam zoo tagnrho, qhov no yuav ua rau muaj kev nce ntawm cov khoom siv crushing cog thaj tsam nce, zoo li nce peev peev.Yog li ntawd, cov txheej txheem tsim siv cov khoom loj, siab crushing yog txoj kev loj hlob ntawm cov txheej txheem crushing.
