Copper (tooj liab) yog cov xim liab-liab, muaj zog ductility, thermal conductivity thiab hluav taws xob conductivity. Vim tias cov khoom no thiab tuaj yeem ua ke nrog zinc, txhuas, npib tsib xee, aluminium thiab titanium rau hauv cov hlau thiab lwm yam khoom, yog siv dav hauv cov khoom siv hluav taws xob, tshuab, tsheb, nkoj tsim kev lag luam thiab cov khoom siv pej xeem thiab lwm yam. Piv txwv li, kev siv tooj liab los ua cov xov hlau, cables, khoom siv hluav taws xob; oxygen-dawb tooj liab los ua ultra-siab zaus hluav taws xob cov raj, tooj dag tsim phom thiab phom loj; dawb tooj liab (tooj liab-zinc-nickel alloy) ua kom elasticity ntawm aviation seev; tin bronze los ua bearings, bushings thiab lwm yam. Copper compounds yog siv rau hauv kev ua liaj ua teb ua tshuaj tua kab thiab tshuaj tua kab; tooj liab tseem yog cov khoom siv tseem ceeb rau kev tsim cov xim pleev xim.
Muaj ntau tshaj 280 hom tooj liab-muaj minerals nyob rau hauv cov xwm, 16 ntawm uas yog cov tseem ceeb ntawm kev lag luam. Tam sim no mining ntawm tooj liab, feem ntau yog chalcopyrite, chalcopyrite, porphyry, malachite thiab lwm yam.
Txawm koj xav taucov kav dej tooj liab, tooj liab rods ,tooj liab daim hlau, peb muaj cov khoom thiab kev txawj ntse kom tau raws li koj xav tau.
