Copper mining thiab nws cuam tshuam rau tib neeg lub neej
Lub hauv paus loj tshaj plaws hauv ntiaj teb tooj liab yog Chile's Chuquicamata Copper Mine, nyob hauv thaj av Antofagasta nyob rau sab qaum teb Chile. Chalauco tooj liab mine yog qhov qhib tooj liab loj tshaj plaws hauv ntiaj teb thiab ua haujlwm los ntawm Chilean National Copper Company (Codelco). Qhov chaw mining yog nplua nuj nyob rau hauv tooj liab reserves thiab tso nyiaj rau ib feem tseem ceeb ntawm lub ntiaj teb no tooj liab reserves. Chile yog lub ntiaj teb loj tshaj plaws tooj liab tsim, nrog rau feem ntau ntawm nws cov tooj liab ntau lawm los ntawm Chalauco tooj liab mine.
Yog li cas tooj liab mined thiab siv? Nov yog cov kauj ruam dav dav rau kev tsuas thiab siv tooj liab ore:
Kev Tshawb Fawb: Ua ntej kev khawb tooj liab tuaj yeem pib, kev tshawb nrhiav yuav tsum tau txheeb xyuas cov peev txheej tooj liab. Qhov no suav nrog kev txhais tau tias xws li geological prospecting, geophysical prospecting thiab drilling.
Mining: Thaum siv tau tooj liab deposits raug txheeb xyuas, kev ua haujlwm tsuas yog ua. Mining txoj kev feem ntau muaj xws li qhib qhov mining thiab underground mining. Qhib-qhov mining yog tsim rau ntiav thiab loj-scale tooj liab deposits, thaum underground mining yog haum rau tob los yog me me-scale tooj liab deposits.
Ore ua: Tom qab mining, tooj liab ore yuav tsum tau mus los ntawm ib tug series ntawm kev ua cov kauj ruam mus rho cov tooj liab hlau. Cov kev kho mob feem ntau muaj xws li crushing, sib tsoo, flotation thiab leaching. Cov txheej txheem no cais cov tooj liab los ntawm lwm cov impurities hauv cov ore.
Refining: Tom qab cov ore ua tiav, cov txiaj ntsig tooj liab yuav tsum tau ua kom zoo ntxiv kom tshem tawm cov khoom seem. Refining txoj kev muaj xws li hluav taws refining, electrolytic refining thiab ntub refining.
Khoom siv: Refined tooj liab tuaj yeem siv los tsim ntau yam khoom siv tooj liab, xws li xov hlau, cables, kav, alloys, khoom siv hluav taws xob, thiab lwm yam. tooj liab yog ib qho tseem ceeb ntawm cov hlau, dav siv hauv kev tsim kho, hluav taws xob, tsheb, aerospace thiab lwm yam. .
Recycling: tooj liab yog ib qho khoom siv dua tshiab, thiab cov khoom siv tooj liab tuaj yeem siv tau thiab rov siv dua. Recycling tooj liab txo qhov kev xav tau ntawm ore mining thiab muaj kev cuam tshuam zoo rau ib puag ncig.
Kev siv cov mining thiab siv tooj liab ore yog cov txheej txheem nyuaj uas muaj ntau yam xws li thev naus laus zis, ib puag ncig thiab kev lag luam. Thaum khawb thiab siv tooj liab, cov peev txheej sustainability thiab kev tiv thaiv ib puag ncig yuav tsum tau xav txog.
Kev siv tooj liab cuam tshuam dab tsi rau tib neeg lub neej? Nws feem ntau suav nrog cov hauv qab no:
Kev tsim kho kev lag luam: tooj liab yog ib qho tseem ceeb ntawm cov hlau siv dav hauv kev tsim kho, hluav taws xob, tsheb, aerospace thiab lwm yam. Copper mining muab cov ntaub ntawv tseem ceeb rau kev txhim kho kev lag luam thiab txhawb kev tsim khoom thiab kev loj hlob ntawm ntau yam kev lag luam.
Kev Ua Haujlwm: Kev tsim kho ntawm tooj liab thiab lwm yam kev lag luam muaj peev xwm tsim tau ntau txoj hauv kev ua haujlwm, suav nrog cov miners, kws tshaj lij, engineers, managers, thiab lwm yam.
Cov nyiaj tau los ntawm kev lag luam: tooj liab tuaj yeem tsim cov nyiaj tau los tseem ceeb rau tsoomfwv hauv tebchaws thiab hauv nroog, muab kev txhawb nqa nyiaj txiag thiab nyiaj txiag rau pej xeem cov kev pabcuam los ntawm kev them se thiab kev cog lus mining.
Txawm li cas los xij, kev siv tooj liab kuj tseem muaj qee qhov tsis zoo rau tib neeg lub neej:
Kev puas tsuaj ib puag ncig: Thaum lub sij hawm cov txheej txheem tooj liab, cov av loj loj, kev ua cov ore, thiab cov pov tseg pov tseg yuav tsum tau ua, uas yuav ua rau muaj kev puas tsuaj rau av, dej, thiab ib puag ncig ecological. Qhov no tuaj yeem ua rau muaj kev cuam tshuam tsis zoo rau hauv zos ecosystems, hom kev sib txawv thiab cov peev txheej dej.
Kev cuam tshuam txog kev sib raug zoo: kev siv tooj liab tuaj yeem ua rau muaj kev tsis sib haum xeeb thiab kev tsis sib haum xeeb, cuam tshuam nrog cov teeb meem xws li cov cai hauv av, txoj cai ua haujlwm thiab kev tsim kho hauv zej zog. Tsis tas li ntawd, cov chaw ua haujlwm miners tej zaum yuav muaj teeb meem kev nyab xeeb thiab kev noj qab haus huv.
Kev txo qis ntawm cov peev txheej: tooj liab yog cov peev txheej tsawg, thiab cov txheej txheem mining siv ntau lub zog thiab dej. Raws li tooj liab mines raug mined thiab noj, cov reserves ntawm cov pob zeb hauv av yuav maj mam txo, tej zaum yuav ua rau depletion thiab mov txwv.
Yog li ntawd, kev siv tooj liab yuav tsum nrhiav kev sib npaug ntawm kev txhim kho kev lag luam thiab kev tiv thaiv ib puag ncig, thiab siv cov txheej txheem mining kom ruaj khov thiab kev tiv thaiv ib puag ncig los txo qhov cuam tshuam tsis zoo rau ib puag ncig thiab tib neeg.
