Cov tooj liab kev lag luam encompasses tag nrho lub neej ntawm tooj liab, suav nrog cov khoom tooj liab), ua rau cov khoom lag luam tooj liab), ua tiav rau kev lag luam tooj liab, thiab siv cov khoom siv tooj rau kev lag luam Tooj liab rau reprocessing.
• Tsuas yog theem me me: Copper mining yog nqa tawm los ntawm qhib-qhov tsuas, av nkos av, thiab cov txheej txheem leaching.
• Cov theem siab: Tooj ORE undergoes foundation benication los tsim cov ntsiab lus tooj liab zoo.
• Cov theem smelting: Tooj liab zoo thiab seem tooj liab yog ua kom zoo nkauj los yog hydrometallurgurgy los tsim tooj liab, uas pabcuam ua cov khoom siv liab cia rau hauv kev lag luam hauv qab.
• Ua tiav theem: Ua kom zoo tooj liab tau ua ntxiv rau ntau cov khoom, nrog rau cov pas luam ntawv tooj liab, cov hlau, cov xov hlau, thiab ntawv ci.
• Kev Siv Cov Qib Xaus: Cov khoom no tau siv dav hauv cov khoom hluav taws xob hauv lub zog, tsim kho, thiab kev thauj mus los hauv tsheb thauj mus los.
Ntws los - tooj liab los rau tooj liab cia
Tooj liab gere yog muaj sib txawv thiab tuaj yeem faib rau hauv ntau hom geological hom, suav nrog:
1. Porphyry tooj liab
2. Sandstone-shale tooj liab
3.. Tooj-nickel sulfide
4. Pyrite-Hom Tooj Liab
5. Copper-uranium-Kub
6. Haiv neeg tooj liab
7. Vein-Yam tooj liab
8. Carbonatite tooj liab
9. Skarn Tooj Liab
Cov Umstream tooj liab tsuas yog muaj txiaj ntsig zoo, thiab cov nyiaj tau los tag nrho thiab cov neeg tau txais txiaj ntsig zoo dua li hauv lwm theem ntawm cov khoom siv khoom.
Nyiaj Tau Los Rau Hauv Kev Lag Luam Tooj Pem Teb Chaav:
• Kev txiav tawm kom tsawg: cov nyiaj tau los ntawm tooj liab zoo (tom qab txiav cov nqi) thiab cov khoom lag luam (sulfuric acid, kub, thiab lwm yam).
• Smelting Sector: cov nyiaj tau los los ntawm kev ua kom zoo nqi thiab tus nqi kis ntawm daim ntawv cog lus thiab cov nqi ntawm cov nqi.
• Ua haujlwm: Cov nyiaj tau los ntawm kev ua tus nqi, uas vam khom tus nqi-ntxiv cov khoom lag luam.
Cov decstream dector tau txiav txim siab los ntawm cov nqi hlau, kev ua tus nqi hlau, thiab cov nqi mining. Vim yog qhov tsis txaus ntawm cov tooj liab, cov ntu ntws sawv cev rau tus nqi siab tshaj plaws hauv kev lag luam tooj liab.
Midstream - SMELTING ntawm tooj liab mloog thiab seem tooj liab
Tooj liab smelting cuam tshuam cov hlau los ntawm ore siv cov hau kev xws li ci, smelting, electrolysis, thiab kev ua yeeb yam. Lub hom phiaj tseem ceeb yog txhawm rau txo cov impurities lossis txhim kho tshwj xeeb cov khoom sib xyaw los ua cov tawv hlau xav tau.
• Pyrometallurgurgy: Haum rau tooj liab sulfide concentrates (feem ntau Chalcopyrite concentrates).
• Hydrometallurgurgy: Haum rau oxidized tooj liab lub siab.
Downstream - Ua kom Zoo Lub Tshuab Tooj
Refined tooj liab tau siv nyob rau hauv kev lag luam xws li lub zog, hluav taws xob, kev tsim khoom, machinery raug, thiab kev tsim kho.
• Tooj liab thiab nws cov aluminium yog qhov thib peb feem ntau cov hlau feem ntau cov neeg siv nyiaj thoob ntiaj teb, tom qab hlau thiab txhuas.
• Hauv kev lag luam hluav taws xob, tooj hluav taws xob, tooj liab yog qhov ntau tshaj plaws siv hlau, pom hauv cov xov hlau, cables, thiab lub nkoj hluav taws xob.
• Hauv kev tiv thaiv thiab aerospace, tooj liab yog siv rau cov mos txwv, phom, thiab kev hloov pauv hluav taws xob rau cov dav hlau thiab cov nkoj.
• Tooj liab tseem siv tau hauv bearings, pistons, hloov chaw, zoo li cov khoom siv hluav taws xob, thiab ntau lub tshuab cua txias thiab cua txias.
• Ntxiv rau, cov khoom siv pejxeem
Cov qauv tseem ceeb no ua piv txwv li tus tooj liab kev lag luam qhov tseem ceeb thiab thoob ntiaj teb hla ntau cov haujlwm.
