Yuav ua li cas mine nickel phaj?
Nickel yog cov khoom siv hlau tseem ceeb nrog ntau yam kev siv hauv kev tsim khoom. Kev khawb ntawm nickel daim hlau feem ntau suav nrog cov kauj ruam ntawm kev tshawb nrhiav, mining thiab refining. Cov txheej txheem mining ntawm nickel daim hlau yuav qhia kom meej hauv qab no.
Ua ntej tshaj plaws, kev tshawb nrhiav kev ua haujlwm yog xav tau rau kev khawb ntawm cov hlau nplaum. Kev tshawb nrhiav feem ntau suav nrog kev tshawb nrhiav thiab kev ntsuam xyuas ntawm cov peev txheej npib tsib xee los ntawm kev tshawb nrhiav geological, tshawb nrhiav geophysical thiab tshawb nrhiav tshuaj lom neeg. Cov haujlwm tshawb nrhiav no yog tsom rau kev txiav txim siab txog geological tej yam kev mob, ore lub cev loj thiab qib thiab lwm yam tsis muaj kev tso nyiaj, thiab muab cov ntaub ntawv raug txhawb rau kev ua haujlwm mining tom ntej.
Qhov thib ob, tom qab txiav txim siab qhov loj thiab qhov chaw ntawm lub cev ore, kev ua haujlwm tsuas yog yuav tsum tau ua. Muaj ob txoj hauv kev tseem ceeb rau kuv cov ntawv nickel: qhib-qhov mining thiab underground mining. Qhib-qhov mining yog hais txog kev khawb ntawm cov ore lub cev ncaj qha rau ntawm qhov chaw, thiab cov mining hauv av yog hais txog kev siv cov mines hauv av thiab qhov av thiab lwm qhov chaw rau kev ua haujlwm mining.
Hauv kev qhib qhov mining, nws yog thawj zaug uas yuav tsum tau tshem tawm cov impurities xws li npog cov av thiab pob zeb ntawm qhov chaw ntawm lub mine, thiab tom qab ntawd siv blasting, excavation thiab lwm yam kev siv rau mine lub ore. Underground mining yuav tsum tau siv cov drilling, blasting thiab cov khoom siv thauj mus los thiab lwm qhov chaw rau ore mining thiab kev thauj mus los.
Thaum kawg, cov nickel ore tom qab mining yuav tsum tau refined thiab purified los tsim cov nickel daim hlau uas ua tau raws li kev xav tau ntawm kev lag luam. Cov txheej txheem refining ntawm nickel daim hlau feem ntau suav nrog cov kauj ruam xws li ore crushing, flotation, smelting thiab purification. Ntawm lawv, flotation yog ib qho kev siv ore sib cais tshuab, uas siv lub cev thiab tshuaj txoj kev los cais thiab purify impurities nyob rau hauv npib tsib xee ore, thiab ces nqa tawm smelting thiab purification txheej txheem thaum kawg tsim high-zoo nickel phaj khoom.
Nyob rau hauv dav dav, lub mining ntawm nickel daim hlau yuav tsum tau mus los ntawm ntau yam kev sib txuas xws li kev tshawb nrhiav, mining thiab refining. Cov kev sib txuas no yuav tsum muaj kev tshawb fawb txog kev tshawb fawb thev naus laus zis, cov cuab yeej mining siab heev thiab cov txheej txheem ua kom zoo zoo txhawb nqa kom ntseeg tau tias cov khoom tsim tau zoo thiab cov txiaj ntsig ntawm nickel daim hlau. Nrog rau kev txhim kho txuas ntxiv ntawm kev tshawb fawb thiab thev naus laus zis niaj hnub no, kev khawb cov nickel daim hlau tseem niaj hnub txhim kho thiab txhim kho, muab kev lees paub txhim khu kev qha kom tau raws li cov neeg xav tau cov ntaub ntawv nickel.
